Engine/Transmission (1998.5 - 2002) Car Wash = DeathCode

[cyborg]

I mentioned this on another post. I use the touchless drive through car wash. I can drive hard for a week and not throw a code, But if I check after doing the carwash I have a 0216.



I just did a before and after car wash code check and yes, the carwash sends the deathcode.



Any suggestions as to which connections to start checking?



Does anyone know what ground/negative connection the dealer is suppose to use for the in-tank pump replacement?



Anyone want to take a stab at this one?

Just had my lift pump replaced at the dealer and they used a wiring harness that plugged into the existing LP harness and ran to the back.



No codes until I hauled the jeep to fourwheel, and then the same two codes 1693 (companion) and the 0216 Lift pump. Guess I get to go back to the dealer and play hardball.
