Wire side of female terminals

Is there continuity?

YES | - Repair short in the wire between the ECM/PCM (A15) and the TP sensor.
NO | - Go to step 12.

12. Connect ECM/PCM connector terminal A15 and body ground with a jumper wire.

13. At the wire harness side, check for continuity between TP sensor 3P connector terminals No. 2 and body ground.

TP SENSOR 3P CONNECTOR

Wire side of female terminals

Is there continuity?

YES | - Substitute a known-good ECM/PCM and recheck (see page 11-6). 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.

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

ECM/PCM CONNECTOR A (31P)

Wire side of female terminals

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 11-6). If symptom/indication goes away, replace the original ECM/PCM.
