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.
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!
