At the wire harness side, check for continuity between TP sensor 3P connector terminal No. 2 and body ground. TP SENSOR 3P CONNECTOR 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. Connect ECM/PCM connector terminal A15 and body ground with a jumper wire. ECM/PCM CONNECTOR A (31P) Wire side of female terminals

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. 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.
