WARNING: This page is about a different car, the 2004 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
Use an ohmmeter which can measure more than 10 MΩ.
- Disconnect knock sensor harness connector.
- Check resistance between terminal 1 and ground.
Resistance: 530 - 590 kΩ [at 20°C (68°F)]
CAUTION:
Discard any knock sensors that have been dropped or physically damaged. Use only new ones.
