Detonation Knock Sensor

Faults in detonation sensor circuit may set Code 34. To test system, see CODE 34 diagnostic procedures in TESTS W/CODES article.

To test sensor, disconnect sensor connector. See the DETONATION SENSOR LOCATION  table. Check continuity between ground and sensor connector terminal. If there is no continuity, replace sensor. Check detonation sensor shield ground wire for continuity to ground. Ensure detonation sensor wire is not routed near spark plug wires or high-output electrical accessories.
