Hey guys own a 2008 x5 4.8 96,646 miles . A week ago I got the valve cover gaskets and spark plugs done with a friend , picked up the car 3 days later and was driving smooth on the 4th day on my way home from work car went to limp mode and I quickly connected my obd 2 pocket scanner and got this code p1637, I shut off the car and waited a minute turned it back on and the car drove fine.
I hooked it up to the x5 to my laptop scanned it with rheingold and nothing came up anyways since then I haven't driven the vehicle afraid to have it go to into limp mode ;(
Previous work done throttle body harness and gas pedal and throttle body changed.
P1637 11505 Throttle position control – control deviation, bank 1 Wiring, throttle motor position sensor, ECM
I read about the harness being shorted out but I'm not sure where to start anyways thank you guys!!
update
connected my x5 to rheingold and these are the latest faults
Do I need to redo the throttle body harness splicing again? I noticed this limp mode comes on when I'm idled for 2 minutes and floor the gas pedal car also shut off and shifted to neutral while in limp mode
If anyone in socal Los Angeles can help or near by let me know thanks
