Dodge Ram 1500

2008 Dodge Ram 1500 5.7 ltre has gone into limp mode. The dashboard warning light that are on are the red flashing lightning bolt, the check engine light and skid indicator. when diagnostic is done the error code is P0340 which is the cranckshaft position sensor which I have replaced. I have also replaced the ETC with no results. Any ideas?


I would consider looking at the camshaft position sensor. You stated that you replace the crankshaft sensor, not the camshaft sensor.

Dodge Code P0340

  • Camshaft Position Sensor Circuit Bank 1 Sensor 1

Code P0340 probable 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

Camshaft Position Sensor Location

The Camshaft Position Sensor (CMP) (3) is located on right side of timing gear/chain cover below generator (1).

Camshaft Position Sensor Removal

  1. First of all, disconnect electrical connector (3) at CMP sensor.
  2. Next remove sensor mounting bolt (3).
  3. Carefully twist sensor (2) from timing gear/chain cover.
  4. Finally, check the condition of sensor O-ring.

GWM Steed

I have a 2010 steed 5, 2.8 Tci bakkie and after reconditioning the engine it cranks but won’t start. I can start and run it using quick start but the moment I stop spraying the quick start it cut off, injectors is on the original cylinder, it just seem that the injectors are not letting fuel in. If someone had encountered this problem before please contact me via email XXX.XXXXXXX@XXXXXX.XXX


Since you have had this apart, I would start by checking for loose connections or things that are not plugged in correctly. Usually a check engine light will illuminate and help guide you in the right direction. If you have any codes present feel free to post them below.

2010 Chavy Impala

I have had no problem with my transmission then Thursday night, after stopping at a stop sign when I went to take off, it wouldn’t move I finally tried 3 no luck, went down to 2 it moved, after getting up to speed I was able to slide in back into drive, but every time I stopped I would have to drop it back down to 2, Friday morning they added fluid to it, when I left for work I had to drop it down to 1, when I tried to shift it back up to drive it wouldn’t go, can a transmission go out that quick or could it be something else?


Can a transmission go out that quick?

Short answer, Yes. Heat is the number one cause for a transmission burning up. A unit low on fluid is exposed to even more heat and would hurry the process. That being said, in most cases if the transmission is burned up the fluid color will be dark and have a burnt smell. If the fluid looks nice and clean then the odds are it is an issue with the valve body solenoids.

How to check transmission fluid color

Finally, using a white paper towel dab a little bit of fresh transmission fluid on it. This will give you something to compare the current fluid color to. No add a little bit of the cars transmission fluid next to the clean on the paper towel and compare.

2004 Volvo XC90

How do you access the brake light relay (REM module) in the rear (left) driver side compartment? Seems you must remove the entire panel for unrestricted access. How is that done?


Rear Electronic Module (REM) Replacement Procedure

2004-volvo-xc90-rem-module-location

The REM Module is a separate unit in the relay box located in the cargo compartment.

  • Switch ignition off.
  • Remove the left side panel in the cargo compartment. HINT: The rear panel in the side panel of the cargo compartment can be removed to change fuses.
  • Release the relay and fuse box.
  • Remove the screw holding the connector so that it is free of its threads. Check that the screw is free with your fingers.
  • Disconnect the connector. Use an open spanner and a support.
  • Remove all relays and shunts bridged to the control module. Note the locations.
  • Release the catch on the rear. Use a screwdriver.
  • Lift and pull out the control module.

1993 Ford Ranger

will not shift into 4wd


First determine which 4WD setup you have.

View of the Borg-Warner model 13-54 with mechanical shift. Electronic shift and model 44-05 are similar

Transfer Case Identification

There are three transfer cases used on the Ranger, Explorer and Mountaineer. There are 2 versions of the Borg Warner 13-54 (mechanical shift and electronic shift), a Borg Warner 44-05 (Control Trac) and an All Wheel Drive (AWD) transfer case.

The Borg Warner 13-54, mechanical shift transfer case, is a 3-piece aluminum part time unit. It transfers power from the transmission to the rear axle and when actuated, also the front drive axle. The unit is lubricated by a positive displacement oil pump that channels oil flow through drilled holes in the rear output shaft. The pump turns with the rear output shaft and allows towing of the vehicle at maximum legal road speeds for extended distances without disconnecting the front and/or rear driveshaft.

Electronic Shift Transfer Case

The Borg Warner 13-54, electronic shift transfer case, transfers power from the transmission to the rear axle and also the front drive axle, when electronically actuated.

This system consists of a push button control, an electronic control module, an electric shift motor with an integral shift position sensor and a speed sensor.

The electric shift motor, mounted externally at the rear of the transfer case, drives a rotary helical cam. The cam moves the 2WD-4WD shift fork and 4H-4L reduction shift fork to the selected vehicle drive position. The system has no select-able Neutral (N) setting.

NOTE: The manufacturer recommends that the Borg Warner 13-54 transfer case equipped vehicles should not be operated in 4WD (whether HI or LOW) mode on dry pavement. Severe drive line torsional wind-up will occur, possibly damaging the drivetrain components.

The Borg Warner 44-05 transfer case operates in the same manner as the 13-54, except that it also houses a transfer case clutch. This clutch, which is controlled by the Generic Control Module (GEM), enables the vehicle to be driven in 4-wheel drive on dry pavement by cycling the clutch to compensate for different front and rear driveshaft speeds (as in turning). The system has a dealer install-able Neutral (N) position mode.

The All Wheel Drive (AWD) transfer case is a 2-piece aluminum, chain driven, viscous clutch type unit. The AWD transfer case is always active in 4-wheel drive, thus producing a full-time engagement. The viscous clutch automatically distributes power to both the front and rear wheels, depending on need.

Radio won’t work


Check fuses first. Then trace wiring. If everything checks out, replace the radio. Use the wiring diagram provided below to assist in your troubleshooting. If the radio comes on but just no sound, your radio thinks its being stolen. You will need the radio code. If it is not in your owners manual call the dealer.

2003 VW Beetle

I have a 2003 VW beetle with 68k miles on it. Some months ago while driving on a hwy the car felt like it was going to die and a code of EPC came on. I took it to a mechanic and they couldn’t find any issue. Seemed fine but to date several times in the past week, the car feels like it is not getting gas and trying to stall, but no code. What to do?


EPC warning light comes on

Since you did have an EPC code we can look into that issue. Odds are they are related.

Electronic Power Control System (EPC)

EPC diagram for VW Beetle

EPC Light on Volkswagen

The EPC warning light, also known as the Electronic Power Control warning light, is a vehicle warning indicator that indicates a problem with your Volkswagen’s throttle system, such as with the throttle pedal, throttle body, traction control, or cruise control. However, the EPC light can indicate other problems with your Volkswagen, as well. Continue reading for how to fix the EPC light on a Volkswagen.

EPC Car Warning Light

When the EPC light comes on in your Volkswagen, it’s a signal that the vehicle needs to be repaired immediately. Your Volkswagen should have enough power to drive to a car dealership or repair shop, but it should not be driven anywhere else. Your vehicle’s throttle may be limited in power as a built-in mechanism to protect the engine.

How to Fix EPC Light on a VW

The EPC warning light can indicate a variety of problems with your vehicle, some of which can be extremely harmful to your engine. It’s important to get your Volkswagen into a repair shop as soon as possible if it’s displaying the EPC light.

Air conditioning problem

Why do I hear water swoshing when my a\c is on but not when not when it is off? Also when on I hear a strange noise when I turn left but not when ot is off. What is this ? Changed out blower motor and resistor.


Could be the normal sounds of a properly functioning R134a air conditioning system. If this is an abnormal sound then you may need to do some investigating in order to narrow down the problem.

but if you hear sloshing (especially on cornering) and finding that your carpets are wet, then check the plenum chamber where the drain holes get blocked on some cars.

2007 Toyota Rav 4

We changed the wheel hub assembly because we expected a low humming noise to be a bad wheel bearing. After changing it, we drove home about 30 miles. The noise was still there and by the time we got home it was louder than ever. And I was scared to drive over 15 mph. I jacked the tire up (passenger rear) and tire was wiggling as if it had a bad wheel bearing. The funny thing is the tire didn’t even wiggle before we changed the Hub assembly. So I am guessing maybe the cv shaft nut wasn’t tightened enough, I don’t know. And if it wasn’t tightened enough or came loose driving could it have damaged the wheel bearing in the hub assembly?

Does it sound like it wasn’t correctly tightened? Also, when I removed the tire and was wiggling the hub it wasn’t tight trying to rock it back and forth. But there was a little play when pushing and pulling it in and out.


Hub bearing noise

Sounds like you shouldn’t have driven it home. But instead circled the block and made the shop aware that the noise was still there. They may have been able to save the part and you some time. At this point you are going to need to take it back(30 miles). And I hope you got a good warranty because you are about to use it.

The shop that performed the repair will take a close look and be able to tell if the new part simply failed or if it was incorrectly installed. Either way, it should not be loose nor would it come loose on its own.
