Q: Four-wheel drive encoder motor not working properly.

asked by on January 12, 2016

The 4X4 indicator light on my truck is in a different setting each time I start my vehicle. When I change it to two-wheel drive from four-wheel drive, you can actually hear the change in the transfer case. I was told it may be the encoder motor.

Hello, Since this recurring regularly the vehicle should be scanned for code. There is a good chance that the wiring to speed sensor on the transfer case has become compromised over time and the wiring harness needs to replaced. This was addressed in TSB 05-04-21-003C. You may need the aid of a mechanic, such as one from YourMechanic, to scan the car for codes and repair the wiring as need since it involves specific pins and routing.

You will need to have the fuel pressure tested to see if it is too low to open injectors and have injectors cleaned or replaced if cleaning does not get them cleaned.
