DTC Description
Confirmed DTC Pending DTC Freeze Frame
P0328 KNOCK SENSOR CIRCUIT HIGH VOLTAGE
Is DTC P0328 indicated?
YES : Check for poor connections or loose terminals at the knock sensor and the PCM. If the PCM was
updated, substitute a known-good PCM See PCM REMOVAL AND INSTALLATION or PCM
UPDATE , then recheck. If the PCM was substituted, go to step 1.
NO : Troubleshooting is complete. If the PCM was substituted, replace the original PCM See PCM
