Some customers may comment on the Service Engine Soon Light coming on. Upon investigation, the technician may find a P1680 diagnostic trouble code.

Correction
Check the resistance of the accelerator pedal position sensors, If the resistance of the accelerator pedal position sensor is within the specifications shown then reprogram the PCM with the latest calibration. If the resistance of the accelerator pedal position sensor is within the specifications shown then replace the PCM. If the resistance of the accelerator pedal position sensor is outside the specifications shown then continue with the diagnostics for DTC P1680. Post back with what you find.
