Is there continuity?

YES

- Substitute a known-good ECM/PCM and recheck (see page 11-313). If symptom/indication goes away, replace the original ECM/PCM.

NO

- Repair open in the wire between the ECM/PCM (A15) and the TP sensor.


  1. Measure voltage between ECM/PCM connector terminals A10 and A20.

Is there about 5 V?

YES

- Repair open in the wire between the ECM/PCM (A20) and the TP sensor.

NO

- Substitute a known-good ECM/PCM and recheck (see page 11-313). If symptom/indication goes away, replace the original ECM/PCM.
