KNOCK SENSOR
- 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 at 25°C (77°F): 500 - 620 k Ohms

CAUTION: Do not use any knock sensors that have been dropped or physically damaged. Use only new ones.
