Ford P0332 OBD-II Trouble Code Definition:
P0332 Knock Sensor 2 Circuit Low
P0332 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0332
Knock Sensor 2 Circuit Low
What does the code mean? OBD-ii Code P0332 definition:
A knock sensor tells the engine computer when one or more of your engine’s cylinders are “knocking”, that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn’t knock. If your knock sensor on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334.

Symptoms Sumptoms of OBD code P0332
You may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms.

Causes Causes of the OBD-II code P0332
Potential causes for a P0332 DTC include (but are not limited to): The knock sensor is faulty and needs to be replaced There is a wiring open/short/fault in the knock sensor circuit The PCM/ECM has failed

Solutions Verify the resistance of the knock sensor (compare it to factory specs) Inspect for broken/frayed wires leading to the sensor Check the wiring and connections leading to/from the knock sensor and PCM/ECM Verify proper voltage is reaching the knock sensor (e.g. 5 volts) Verify proper grounding of sensor and circuit Replace the knock sensor Replace the PCM/ECM
