Have a code come up p0332 on a cadilillac 2004


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

How do you correct repair code P0332 and how what should the cost be for a 2004 gmc denali?


P0332 Is set by a knock sensor, desiganted by GM as "Knock Sensor 2".

There could be many causes for this, from a misfire, to a loose sensor; so an appraisal from anyone without access to the vehicle is out of the question.

1995 ford exploere check engine light is on/loss of power


P0327 - Knock Sensor Circuit Low Voltage
P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)

Have you had the engine worked on? this looks like maybe the spark knock sensor is either disconnected or has been overtightened in the block, to check this locate the knock sensor at the base of the cylinder block just above where the oil pan bolts to the block, it is round (with a wire connector going to it) with a large hex nut configuration to pull it out, it is in the water jacket so if you do pull it drain the cooling system and the engine block, if you replace it DO NOT OVER-TIGHTEN IT! tighten to suggested torque setting in factory service manual.
