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 #1 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0327 DTC. This P0327 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0328, P0329, P0330, P0331, P0332, P0333, and P0334.

P0332 DTC Code - Knock Sensor 1 Circuit Low Input (Bank 2)
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.

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

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

P0331 Spark Knock has not been sensed

The spark knock or ping is 2 flame fronts colliding in the combustion chamber, the shock wave of which can eventually blow holes through the piston crowns if severe enough. In late model engines the causes can include:
- fuel octane too low
- EGR system malfunction
- knock sensor (if equipped) malfunction
- PCM software not retarding ignition timing as required
- high engine operating temperature
- lean fuel mixture
- carbon deposits on piston crowns/combustion chambers

Hope helps.

Hi Sandra!
The trouble codes listed are defined as:

P0141 Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

P0300 Random/Multiple Cylinder Misfire Detected

P0331 Knock Sensor 2 Circuit Range/Performance (Bank 2)

PO300 & PO331 are possibly symptomatic of issues caused by PO141, which would have a direct influence on the air/fuel mxture... which could cause missing and knocking.

So the first thing I would try is replacing the Bank 2 Oxygen Sensor, after making sure the wiring and connections to that sensor are in good shape.

Does the engine show any physical issues such as loosing coolant, smoking exhaust, overheating? A blown or leaking head gasket on the #2 bank could also present these (among other)
codes.

Good luck and let me know how it goes!
