COMPONENT INSPECTION
Knock sensor





1. Disconnect knock sensor sub-harness connector.
2. Check resistance between terminal (2) and ground. Approximately 500 - 620 k Ohms [at 25°C (77°F)].
- It is necessary to use an ohmmeter which can measure more than 10 M Ohms.

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