COMPONENT INSPECTIONKnock 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.
