Resistance Inspection

Turn the ignition switch to LOCK.
Disconnect the knock sensor connector.
Measure the resistance between the knock sensor terminals A and B.
- If not as specified, replace the knock sensor.
- If the knock sensor is okay, but PID value or PCM terminal 57 and 66 voltage are out of specification, perform the "Circuit Open/Short Inspection."
