SYMPTOM
P0330-KNOCK SENSOR NO.2 CIRCUIT

TEST NOTE
This symptom is diagnosed using the test P0325-KNOCK SENSOR NO.1 CIRCUIT.

WHEN MONITORED
With the engine running >1312 RPM, coolant temp >65.25° C (149.45° F), MAF >250mg/tdc and no ECT, MAF or CAM Sensor DTCs.

SET CONDITION
The Knock Sensor error program internal to the PCM is on, the Knock Sensor voltage is <0.49 volt, and the value of the Knock Sensor changes less than 0.06 volt for >11 seconds. One Trip Fault. Three good trips to turn off the MIL.

POSSIBLE CAUSES
- Good trip equal to zero
- Knock sensor signal circuit shorted to voltage
- Knock sensor signal circuit open
- Knock sensor return circuit open
- Knock sensor signal circuit shorted to ground
- Knock sensor signal circuit shorted to knock sensor return circuit
- Knock sensor
