Knock Sensor Module: Service and Repair
REMOVE OR DISCONNECT
CAUTION: To prevent internal PCM damage, the ignition must be OFF when disconnecting or reconnecting power to PCM (for example,
battery cable, PCM pigtail, PCM fuse, jumper cables, etc.). The ignition should be OFF for at least 10 seconds before disconnecting power to the
PCM so the IAC valve has time to move to the engine OFF position.
1. Disconnect the negative battery cable.
2. Remove the RH hush panel.
3. Disconnect the PCM electrical connectors (2).
NOTE: PCM removal is eased when the glove box door is opened.
4. Remove the PCM mounting bolt (1).
