Hyundai Verna Fluidicair bag sign is on my dash board panel when i start my car and not goes off


This would indicate there is a malfunction in the air bag system.

Air Bag Light

Each time the vehicle is started the computer performs a check on the air bag system. If any malfunction is noticed the air bag light will be illuminated and the air bag function disabled. When the air bag light is turned on it indicates the air bag is no longer functional. An air bag code will also be stored int he computer.

The most common reason for an air bag light to come on is from a loose ground. Many of the sensors are placed in areas that are prone to rust and or corrosion. Sometimes cleaning the grounds is all that is needed to repair the issue. Other times actual sensor failure is the cause and the sensor will need to be replaced.

A scan tool will be required to extract the individual codes that will pinpoint the exact location of the issue.

Hyundai Sante FeWhat is the most I should need to pay for a complete timing belt kit removal/replacement? {in zip code 48471}…..thanks


Would be helpful to know what engine is in your vehicle as it came with 3 options.

Estimate Worksheet

2.4L : engine timing belt component kit cost = 154.70; labor hours = 5.1

2.7L : engine timing belt component kit cost = 150.27; labor hours = 5.5

3.5L : engine timing belt component kit cost = 127.19; labor hours = 5.5

Add an additional 150 to the kit price and 3 hours labor if you want the kit that includes a water pump.

Part cost(154.70) + markup(75%) = 270

Part cost with water pump(304.70) + markup(75%) =533

Labor hours(5.5) x hourly rate(120) = 660

Misc. Charge(shop supplies) = 25


Timing Belt Kit Replacement Estimate

Without water pump added = 1218+tax(6%) = $1291.00

With water pump added  = 955+tax(6%) = $1012.00

These auto repair estimates are the average prices. It may be a bit less expensive at a local shop compared to a dealership. However you can supplement the labor rate with whatever the shop rate is and apply it the same way. A Dealerships overhead is higher than smaller shops and tends to be a bit more expensive.

Hyundai XG350My car was in an accident. I hit a fire hydrant on my driver side front wheel and now the wheel won’t respond when I turn the steering wheel. What is the issue?


Wheel Won’t Respond

You have broken, at a minimum, the steering tie rod. There may be more than that broken. Possible broken strut mounts, control arms, etc. Anytime a vehicle is wrecked it is a good idea to have the vehicle physically looked at by a professional mechanic. Have an alignment done to help avoid premature tire wear.

Proper tire alignment is critical to the tread-life of your tires as well as to your car’s steering performance. Improper alignment typically produces uneven tread-wear (figure H) either to the inside or outside shoulder of your tire. Simple alignments, at the proper intervals, will save you money in the long run in tire costs. It’s best to have your car aligned at least once a year.

2012 Hyundai ElantraHi, I have a misfire on #4 cylinder and I’m going to replace the ignition coil but I’m not sure which coil is for #4 cylinder. I need the cylinder order. Can anyone help me on this?


Cylinder Order

The front of the engine or closest to the alternator belt is where you begin. The cylinders are in order from 1 through 4. So Cylinder number one would be the closest to the alternator belt.


The engine operating conditions (speed, load, warm-up condition, etc.) are detected by various sensors. Consequently these sensor signals and the ignition timing data, signals to interrupt the primary current are sent to the ECM. Therefore the ignition coil is activated, and timing is controlled.

Hyundai ElantraMy heater is blowing cold air. All hoses are hot, thermostat is new, system flushed. I can’t find the blend door actuator. Is this the problem? How can I fix this?


That is definitely a possibility.  Consequently it may also be a stuck blend door or damaged unit. There is also the possibility that a vacuum hose is loose or damaged. The blend door actuator should be located behind the center of the dash, on the left end of the HVAC housing. In the diagram the blend door is referred to as the temperature door. The actuator is referred to as a vacuum motor.

The heater unit houses the heater core, vent/defrost mode door, temperature blend mode door, and the fresh/recirculated air mode door. Coolant flows continually through the heater core. In conclusion the amount of heat is controlled by blending air across the heater core with fresh/recirculated air being vented to selected outlets.

Hyundai AccentHi, we thought we had a failing fuel pump as the car was having intermittent starting issues, sometimes it would start other times not. It always turned over but wasn’t getting fuel. So we replaced fuel pump with new and still had problem, worked out the problem was a bad earth(ground) and old pump worked fine. My problem is that when the new pump was installed, at idle it is normal and quiet but when driving the faster you drive the louder it gets, it is a hum sort of fuel pump noise that is louder than the engine noise. Thought maybe new pump was faulty so took back out and replaced it with the original old one, now that is doing the same thing ???? Noise was never a problem before. I’ve checked the sock like filter on the base of the pump and other parts within the plastic assembly and there is no obvious blockages ……. the car is not hesitating or acting as if it’s starving for fuel when accelerating it’s just the noise of the pump …… any ideas on why this would happen ??? I would really appreciate any advice. Thanks heaps Ben


Fuel Pump Noise

Noise is a form of vibration. That being said, many d0-it-yourself’ers tend to leave out the rubber o-ring gasket. The fuel pump is sometimes difficult to seat with the new rubber o-ring or with the old one for that matter. So many have let out the o-ring. This can cause two problems. One problem is that is creates an evap system leak. And two, it can cause excessive fuel pump noise. The fuel pump noise will resonate and without the o-ring in place it turns the fuel tank into a loud speaker. Of course the noise would be louder on an empty tank and get quieter with a full tank.

I want to also suggest that you double check the area under the rear seat. Make certain any noise dampening was put back into place. Also make sure the inspection panel is back in place and properly secured. Make sure the fuel filter is also secured back in its bracket.

Fuel Pump Replacement

To Remove:
  1. Press the two taps under the rear seat and raise the seat.
  2. Detach the inspection panel of the fuel pump.
  3. To reduce the internal pressure of the fuel lines and hoses, start the engine with the fuel pump disconnected and wait until it stops.
    Note: Be sure to reduce the fuel pressure before disconnecting the fuel main pipe and hose otherwise fuel will spill out.

  1. Disconnect or remove the following:◦Negative battery cable
    ◦Eye bolts while holding the fuel filter nuts securely
    Cover the fuel filter with a shop towel to avoid residual gasoline from splashing.

    ◦Fuel filter mounting bolts
    ◦Fuel filter from the fuel filter clamp

    To Install:

    1.Install or connect the following:

◦Fuel filter from the fuel filter clamp
◦Fuel filter mounting bolts
◦Eye bolts
◦Negative battery cable
◦Inspection panel of the fuel pump
◦Rear seat

2009 Hyundai SonataWe have a code p0340 CEL and the camshaft sensor has been changed. I need to replace the 3 wires in the harness from the ECM to cps could you provide the wiring diagram? It is a 2009 Hyundai Sonata 2.4 GLS.


Hyundai Code P0340 – Camshaft Position Sensor ‘A’ Circuit Malfunction Bank 1 Or Single Sensor

First of All the Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. Therefore this information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. Hence the camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. As a result the changing gap causes the magnetic field near the sensor to change. While the change in the magnetic field cause the voltage from the sensor to change.

In conclusion when the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Code P0340 Possible causes

– Faulty Camshaft Position Sensor
– Camshaft Position Sensor harness is open or shorted
– Camshaft Position Sensor circuit poor electrical connection
– Faulty starter motor
– Starting system circuit
– Dead (Weak) battery

2004 Hyundai XG 350I have a miss in my car. The spark plugs have been changed. Also replaced 2 coil packs and replaced plug wires. But there is still a ‘miss’ in the engine. What could I check out next? Any ideas what it could be?


If the check engine light is on, please post the codes below in the comments for further information.

Misfire Counters

Misfire Counters
Whenever a cylinder misfires, the misfire diagnostic counts the misfires. Then the misfire diagnostic notes the crankshaft position at the time the misfire occurred. These misfire counters are basically a file on each engine cylinder.

A current and a history misfire counter is maintained for each cylinder. The misfire current counters indicate the number of firing events out of the last 200 cylinder firing events which were misfires. A misfire current counter displays real time data without a misfire DTC stored. The misfire history counters indicate the total number of cylinder firing events which were misfires. The misfire history counters display 0 until the misfire diagnostic has failed and a DTC P0300 is set. Once the misfire DTC sets, the misfire history counters will be updated every 200 cylinder firing events.

The misfire counters graphic illustrates how these misfire counters are maintained. If the misfire diagnostic reports a failure, the diagnostic executive reviews all of the misfire counters before reporting a DTC. This way, the diagnostic executive reports the most current information.

When crankshaft rotation is erratic, the control module detects a misfire condition. Because of this erratic condition, the data that is collected by the diagnostic can sometimes incorrectly identify which cylinder is misfiring. The misfire counters graphic shows there are misfires counted from more than one cylinder. Cylinder #1 has the majority of counted misfires. In this case, the misfire counters would identify cylinder #1 as the misfiring cylinder. The misfires in the other counters were just background noise caused by the erratic rotation of the crankshaft. If the number of accumulated is sufficient for the diagnostic to identify a true misfire, the diagnostic will set DTC P0300.

Misfire Counter Information

Use Techline™ equipment to monitor misfire counter data on OBD  ll compliant vehicles. Knowing which specific cylinders misfired can lead to the root cause. Even when dealing with a multiple cylinder misfire. Using the information in the misfire counters identify which cylinders are misfiring. If the counters indicate cylinders numbers 1 and 4 misfired, look for a circuit or component common to both cylinders number 1 and 4. Such as an open ignition coil in an electronic ignition system.

The misfire counter information is located in the specific eng. menu, misfire data sub-menu of the data list.

The misfire diagnostic may indicate a fault due to a temporary fault. This is not necessarily caused by a vehicle emission system malfunction. Possible malfunctions include the following conditions:

  • Contaminated fuel
  • Running out of fuel
  • Fuel fouled spark plugs
  • Basic engine fault
