Note. Bank 1 is located on right side of engine. Bank 2 is located on left side of engine.
- Turn ignition off. Inspect knock sensor for correct installation. For location (Схема №2)or (Схема №3). Repair as necessary and retest system. If knock sensor is installed correctly, go to next step.
- Disconnect knock sensor harness connector. Measure resistance between knock sensor terminals. If resistance is 4.5-5.5 megohms, go to next step. If resistance not 4.5-5.5 megohms, replace knock sensor and retest system.
- Disconnect PCM harness connectors. (Схема №5) Check continuity of White/Red wire between knock sensor harness connector and PCM harness connector PI-1 terminal No. 52. (Схема №6) If continuity exists, go to next step. If continuity does not exist, repair open in White/Red wire and retest system.
- Check continuity between ground and knock sensor harness connector White/Red wire. If continuity exists, repair short to ground and retest system. If continuity does not exist, go to next step.
- Check continuity of Gray/Red wire between knock sensor harness connector and PCM harness connector PI-1 terminal No. 43. If continuity exists, go to next step. If continuity does not exist, repair open in Gray/Red wire and retest system.
- Check continuity between ground and knock sensor harness connector Gray/Red wire. If continuity exists, repair short to ground and retest system. If continuity does not exist, replace PCM and retest system.
