Encoder motor is bad on my 2000 gmc jimmy, I have googled this and it seems to be a common issue with the gmc jimmy's , was there ever a recall for this issue. This is going to cost me 650.00 to fix, I have had nothing but front end issues on this car since I got it, I have spend about 2500.00 in front end repairs and now this.

SOURCE: where is the 4x4 encoder motor sensor located on my 03 sierra

the encoder motor sensor is inside the encoder motor. the encoder is located at the transfer case. Remove the encoder and by part number 88962315 this is the sensor. you will have to retime the motor after
hope this helps

Try cleaning the fuel filter, air filter, and check the sparkplugs. Along with that also clean the throttle body using the injector cleaner.f that is not helping, then the other possibility can be faulty cam position actuator solenoid. Basically it's how the PCM controls the valve timing. It sounds like obviously there is a problem in the system and it's keeping the cam retarded.
There isn't too much to the system, PCM, cam actuator solenoid & related wiring but it will take a Tech II (factory scan tool) to diagnose properly.Also you can get it scanned at autozone service center for free.-------------- This are the possibilities to be checked.Hope this helps.Thanks.
