Knock Sensor
Note: Use an ohmmeter which can measure more than 10 M Ohms.
1. Disconnect knock sensor harness connector.




2. Check resistance between terminal (2) and ground.

Resistance: 532 - 588 K Ohm [at 25°C (77°F)]

CAUTION: Discard any knock sensors that have been dropped or physically damaged. Use only new ones.
