code P1286. truck is deleted. feels like pedal is dead / very delayed. tested accelorator pedal and its good. did a few resets but still nothin. need help!
Ok. Ya I did check both supply voltage and the are reading 5 volts and grounds are good and signals are good coming from pedal when I back probed and it pedal sweep it was consistent with voltage change. I’m thinking maybe ecm calibration gone bad or bad tune.
