DTC P1324: Knock Sensor Power Source Circuit Low Voltage Reset the ECM/PCM (see page 11-4). Turn the ignition switch ON (II). Is DTC P1324 indicated? YES - Go to step 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the knock sensor and at the ECM/PCM. Turn the ignition switch OFF. Disconnect ECM/PCM connector A (31P). Check for continuity between ECM/PCM connector terminals A8 and A20. ECM/PCM CONNECTOR A (31P) 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 - Go to step 6. Disconnect the knock sensor 3P connector.

Connect the knock sensor 3P connector terminals No. 2 and No. 3 with a jumper wire. KNOCK SENSOR 3P CONNECTOR JUMPER WIRE Wire side of female terminals Check for continuity between ECM/PCM connector terminals A8 and A20. ECM/PCM CONNECTOR A (31P) Wire side of female terminals Is there continuity? YES - Replace the knock sensor. NO - Repair open in the wire between the ECM/PCM (A8, A20) and the knock sensor.
