Whenever I start my car 1st time in the morning after the car not being used for more than 10 to 12 hours, Engine shuts off whenever I press clutch initially for first 2 to 3 KM’s. Once I drive more than 2 KM’s the car functions well and the engine also does not shut off then. This happens only for first 2 to 3 KM’s when I start the car after long interval.
Mechanic checked the car and changed the Air Filter, Ignition Coils, All Spark Plugs, Also got the Fuel Injectors Serviced and tested.
Got the car checked on ODB Device which showed errors –
Manifold Absolute Pressure (MAP) Sensor Circuit High Voltage (P0108) Temporary. but this error went away after getting all the above things done, car runs well but at the start as mentioned it shuts off for initial KM’s.
Need some expert comments.



Driving it for a couple of weeks may allow the computer to set a new code. The old code that is no longer there may come back. In the meantime you can look at a couple other things.

The engine stays running fine when it is warmed up. So there could be a failing ECT Sensor(Engine Coolant Temperature). 

There could also be a vacuum leak or a failing IAC Valve(Idle Air Control). No matter the issue, for right now it would be a good idea to drive it and see if the light comes back on.

D4 indicator light comes on when ignition is turned on (does NOT blink); goes off in a few seconds or as soon as the engine is started. All the online comments I have found relate to the D4 light blinking. Any clues as to the light being on without blinking for only a few seconds? Car drives normally and I don’t notice any difference in transmission operation (I’ve been driving this car since early 2007).


Yes it would seem that there are more instances with the D4 light flashing than the D4 light just coming on. But in just about all cases the issue has to do with a fault in the transmission computer. Since the light goes out quickly, i do not think you are quite at the point of needing to repair it just yet. The ol’ “Don’t fix it if it ain’t broke” bit comes to mind.

Having troubles with the heating/AC/entire climate control in my car. No power is going to the buttons, they don’t light up and nothing is working. Because it seems like no power is going to the buttons, it then does not heat or cool and no fans turn on, nothing. Wondering if it disconnected somewhere, but I don’t know where to look.



First thing to check would be the fuses. This is where the power comes from.

Next you could check the connections on the back of the switch/controls for power and connection. Then check the wiring to see where the power loss is located in case a wire is cut or damaged if no power is found.

Automatic Temperature Control System DESCRIPTION

SYSTEM OPERATION

The automatic temperature control regulates air temperature, air mix door control and blower speed to maintain operator “set temperature.” This is determined by ambient temperature, in-vehicle temperature, amount of sunload, set temperature and A/C switch signals. The air outlet door, intake door and compressor magnet clutch are controlled by the manual operation of each switch.
When the engine coolant temperature is low, the air outlet door position is detected by the microswitch, if this is set in B/L, FOOT or FOOT/DEF blower speed is controlled to prevent cold air from being discharged into the floor area.
The intake door control is selected by changing the REC switch position. The outlet door control is selected by changing the mode switch. When the A/C switch is ON, the thermistor detects evaporator temperature. The thermo control amplifier controls compressor magnet clutch control operation depending on evaporator temperature.

SYSTEM COMPONENTS

Refer to Fig. 1 for system component input and output controls and switch sensor usage combinations.

Fig.1

2010-honda-civic-automatic-temperature-control-system-diagram
Air Mix Door Motor

The air mix door motor rotates so that the air mix door is opened to a position set by the auto amplifier. Motor rotation is sent through a shaft. The air mix door position is fed back to the auto amplifier by P.B.R. built into the air mix door motor.
Ambient Temperature Sensor
This sensor transforms ambient temperature into a resistance value which is input to the automatic amplifier.

Automatic Amplifier

This amplifier has a built in microcomputer enabling it to accept data and provide precise system control which is necessary for driving the automatic air conditioner mode. This microcomputer has a self-diagnosis mode program.

Automatic Amp. Relay

When the A/C and fan switch are ON, the auto amp. relay operates and transmits A/C operation signals to the auto amplifier.
In-Vehicle Sensor
These sensors convert the temperature value of inside air which is drawn through the aspirator fan, into a resistance value which is input to the automatic amplifier. The head level sensor detects upper half body level temperature and the foot level sensor detects foot level temperature.

Microswitch

The microswitch is at the side link of the heater unit and operates the link in response to the position of the mode switch.
Potentiometer Temperature Control (P.T.C.)
The P.T.C. is used to set desired in-vehicle temperature.

Fan Control Amplifier

The amplifier controls main radiator fan speed (HI or LO) according to base current transmitted from the automatic amplifier when the compressor operates.

Sunload Sensor

This sensor is located in the right defroster grille assembly. It transforms sunlight into a current value, which is then input to the auto amplifier.

Water Temperature Sensor

This sensor converts water temperature value at heater core entrance into resistance value, then inputs voltage that varies according to resistance value change into the auto amp.

idles for 10 minutes then cuts out any advice please?



When it dies and will not start, look for what it is not getting. Most common would be spark. Reason is once it warms up the ignition control module starts to fail. This is the most common failure part that causes this issue. It is also common for some to just replace the entire distributor.

If my heat gauge is reading all the way hot but motor and coolant is only warm to the touch and no smoking or boiling over would it be the thermostat?



Probably Not. The heat gauge uses a ECT Sensor to indicate the engine coolant temperature. Sometimes if there is an air pocket the sending unit will read hot until the cooling system is properly bled. Once the system is properly bled you can use an infrared hand held temperature gun to check the accuracy of the gauge.

The first thing I would check would be the coolant level. Also confirm the temperature gauge sending unit wire is connected. If it has become disconnected it will read full hot all the time with Key in ON position.

If you just worked on it and are now having the issue, check around the area you were working to make sure you didn’t accidentally leave a wire disconnected.

You can check the the sensor by removing it and using checking the resistance ohms.

I was driving when the Brake, tire pressure, traction control and power steering warning lights came on. The emergency brake is definitely not on, the power steering is working, and I’ve checked the tire pressure.



After checking the tire pressure and tires for even wear it may be necessary to calibrate the TPMS – Tire Pressure Monitoring System. Also check the brake fluid level. If the light came on while driving in slick conditions it means the system was activated and should reset after a re-start. If the light go out after a re-start it may have been just a one time thing.

2014-18 Honda CR-V

TPMS Calibration Inspection

Ensure tire pressure is properly adjusted to specified tire pressure listed on doorjamb label before doing TPMS calibration.

Calibration begins when TPMS switch is pressed. Calibration is completed after driving in an ideal driving condition 31-62 mph, driving steadily without much acceleration or deceleration for about 18 minutes. Full functionality of system cannot be performed properly if calibration is not completed.

Perform TPMS calibration after doing following items: Adjusting tire pressure, rotating tires, replacing tires, updating VSA modulator control unit, or replacing VSA modulator control unit.

Calibration process gets interrupted if vehicle moves. Perform troubleshooting if indicator does not go off after two seconds, keeps blinking or stays on when ignition switch is turned ON (II).

  1. Stop vehicle and shift into P or N position.
  2. Turn ignition switch to LOCK (0).
  3. Turn ignition switch to ON (II) and wait to see low pressure indicator come on for two seconds and then off.
  4. Do not drive vehicle and wait for 45 seconds as is.
  5. If calibration is completed, indicator does not come on. If calibration is not yet completed, then indicator comes on for two seconds and off.
Calibration Procedure

Vehicle must be stopped with transmission in P or N.

If indicator does not blink, inspect TPMS switch.

  1. Ensure tires are inflated to specified tire pressure listed on doorjamb label.
  2. Turn ignition switch to ON (II).
  3. Press TPMS switch for three seconds.
  4. When calibration successfully begins, indicator blinks twice.

2005-17 CR-V VSA Warning Light

VSA(Vehicle Stability Assist) warning light is used to warn of a system fault. Lamp monitors condition of anti-lock brake system. It will be lit during engine start up, but should go off when self diagnostic system determines that system is operating properly. If lamp remains lit, a fault in anti-lock brake system is indicated. Even though system is operating properly, activation indicator may come on if VSA switch has been manually turned off, vehicle goes into a spin, one drive wheel is stuck, electrical interference is present, or when VSA or ABS operates continuously for a long time.
After diagnosis and repair of system, lamp may be turned off as follows:
1.
With ignition switch in OFF position connect a suitably programmed scan tool to DLC located under lefthand side of instrument panel.
2.
Place ignition switch in ON position and follow scan tool instructions to clear DTCs.

2006-18 CR-V ABS Light

ABS warning light is used to warn of a system fault. Lamp monitors condition of anti-lock brake system. It will be lit during engine start up, but should go off when self diagnostic system determines that system is operating properly. If lamp remains lit, a fault in anti-lock brake system is indicated. Even though system is operating properly, indicator may come on if vehicle goes into a spin, one drive wheel is stuck, only drive wheels rotate, electrical interference is present, or when ABS operates continuously for a long time.

After diagnosis and repair of system, lamp may be turned off as follows:

  1. With ignition switch in OFF position connect a suitably programmed scan tool to DLC located under lefthand side of instrument panel.
  2. Place ignition switch in ON position and follow scan tool instructions to clear DTCs.

I recently replaces the ignition lock cylinder and had key programmed to car. Now I can’t use my windshield wipers nor Radio. I have checked the fuses and all look good. Any suggestions. Thank You.



The first thing I like to do when I have more than one electrical feature no longer working is to look for a common between the two. I will pull up a wiring diagram for each circuit and look for a common fuse, ground or relay. And of course any recent work done is a good place to look as well. I would think Fuse #7 would be the culprit. Fuse #7 supplies power to the wiper switch and Navigation display(also radio display I think) and the immobilizer which has to do with anti-theft which may have been an issue caused when reprogramming the key.

What to check:

  • Fuse 5, 7, 10 & 32. No need to check fuse 22 or 23 as the car wouldn’t start if they were bad.
  • PGM-FI Main Relay 2

How to Replace Wheel Stud On 1998 Honda Accord

 Auto Repair Questions, Honda  Comments Off on How to Replace Wheel Stud On 1998 Honda Accord
Dec 162019
 

Honda Accord

We are trying to figure out how to replace the front wheel studs on a 1998 Honda Accord EX, but all methods we’ve seen described so far involve a grinding, but we do not have one, nor wish to purchase one. Since it is continuously referred to as “the grinding method”, that would seem to imply there are OTHER methods as well, correct? I mean, Honda couldn’t possibly have designed these Accords to only be able to replace the wheel lug nut studs on them by taking a grinder to them, right? lol



You are correct, there is another method for replacing the wheel stud. It is the method of doing it “the right way”. If the manufacturer didn’t want all the material on the wheel stud they would have made the studs already cut. All the grinding will weaken the stud and I do not recommend it.

1998-honda-accord-hub-stud-removal-diagram

Replacing the front wheel lug stud

Replacing a front wheel lug stud will require removal of the front steering knuckle from the vehicle and replacement of the axle nut. In addition to replacing the axle nut, on some Accord models, the front wheel bearing must be replaced, as the front hub is pressed into the bearing. On these models, the hub must be pressed out of the bearing to allow enough room for the wheel lug stud to be removed from and installed into the hub.

To replace a front wheel lug stud proceed as follows:

  1. Remove the front knuckle assembly. For specific details, refer to the procedure in this section.
  2. On 1996–97 Accord models, press the front hub out of the wheel bearing assembly.On some models of the Accord you may have to unbolt the hub sub-assembly from the knuckle.
  3. Place the back side of the hub squarely over a suitable deep well impact socket just large enough to clear the button head of the stud.
  4. Using a hydraulic press, or a suitable ball peen hammer, drive the stud out of the hub into the socket.To install:
  5. Place the front side of the hub flush with the deep well socket used for removal. Make sure the socket is deep enough to ensure that the threaded portion of the stud will not contact the bottom of the socket when it is fully installed.
  6. Drive the threaded portion of the stud though the back of the hub until the button head portion of the stud bottoms on the hub.

7.On 1996–97 Accord models:

1.Replace the wheel bearing. For specific details, follow the bearing removal and installation procedures in this section.

2.Press the hub into the wheel bearing assembly.

8.If the hub sub-assembly was removed, install it onto the knuckle.

9.The balance of the installation procedure is the reverse of removal, noting the following points:

◦For every stud replaced, use a new wheel lug nut. Torque the lug nuts to 80 ft. lbs. (108 Nm).

◦Install a new axle nut and torque the nut to 181 ft. lbs. (245 Nm), then stake the nut.

I had a bolt missing from my head cover and when I replaced it with the wrong bolt it caused a gap in the gasket and caused an oil leak. Is the head cover gasket the only thing I need to replace once I get the correct bolts?



There are some seals or grommets around the head where the spark plugs go. These should be replaced. They should come with the valve cover gasket kit.

Valve Cover Replacement

Except 2.4L Engine

  1. Remove the spark plug wires by twisting side to side and gently pulling. Note or label their location and place aside.
  2. Starting from the outside and working inward, using a 10mm wrench or socket with an extension and ratchet, remove the fasteners securing the valve cover to the cylinder head.
  3. If equipped, remove all hoses and brackets.
  4. Carefully lift the cover off the cylinder head. Use care to not loose the sealing grommets when lifting the cover. Place the cover upright in a clean, protected area. If the cover is stuck onto the cylinder head, using a suitable prytool carefully pry the cover upward at the corners. Move each corner no more than a 1/16 inch at a time.

    Tighten the rocker arm (valve) cover bolts in the sequence shown-3.0L engine

To install:

  1. Thoroughly clean and inspect the gasket surface of the cover and cylinder head. Rubbing alcohol or a suitable brake cleaner works well for this application.
    WARNING

    Protect the eyes and exposed skin from contact with cleaning agents. Do not use near an open flame.

  2. Inspect the rubber valve cover gasket, the sealing grommets, and the seal around the spark plug holes. If the gasket or seals are brittle, cracked or damaged, replace them. If the old gasket and seals are not worn or damaged they can be reused once cleaned.

To clean the valve cover gasket:

  • Place the gasket in a suitable, clear plastic bag.
  • Spray a small amount of brake cleaner, or pour about 2 ounces of rubbing alcohol into the bag.
  • Close the end of the bag and swish the cleaning fluid around, making certain the entire gasket has been thoroughly saturated. Do not leave the gasket in the bag for more than 5 minutes.
  • Remove the gasket, and wipe clean with a paper towel or clean soft cloth.
  1. Apply a liquid, non-hardening gasket sealant, such as Honda sealant part No. 08718-0001 or 08718-0003 to the valve cover side of the spark plug opening seals and press them into the valve cover.
  2. Install the valve cover gasket securely into the groove in the valve cover.
  3. Apply a 1/2 inch bead of sealant to the corners of the gasket, where the gasket meets the cylinder head and the camshaft journal cap.
  4. Install the grommets if removed, and tighten the valve cover fasteners from the inside out evenly in three steps. For the 2.2L and 3.0L engines, tighten the retainers in the sequence shown in the accompanying figures. Tighten the valve cover fastener, as follows:
    • 4-cylinder engines: to 86 inch lbs. (9.8 Nm).
    • 3.0L engine: 108 inch lbs. (12 Nm)
  5. The remainder of the assembly procedure is the reverse of the removal sequence.
