SOURCE: knock sensor code, p0330

The knock sensors either work or they don't. When they do not, the light comes on. All that a knock senor is is a piezo crystal that vibrates at the frequency that is comparable to engine "knock", and sends that yes/no signal to the ECU. There are 2 knock sensors, and both are bolted to each side of the engine interior walls, under each cylinder head. You have to remove both of the intake manifolds to access the knock sensors and their wiring.
Price to pay? My flat rate book suggests 3.7 hrs to change both. 3.7 hrs times your local labour rate, plus the price of the 2 sensors and/or wiring, and the price for the gaskets for the upper & lower manifolds. Depending on your location, you could quickly spend over $500.00.

SOURCE: More knock sensor blues

Forgive me for asking, but are you sure you replaced the knock sensors? They are underneath the intake plenum. I'm just wondering if maybe you replaced the Oxygen sensors by accident. Anyway, so that you know, this is a very common problem (the knock sensors). Gm has issued a bulletin, something to do with the rear knock sensor under the intake getting contaminated by water, and they recommend a new sensor installed with silicone around the gasket to protect it. Also, the wiring harness is particularly tasty to rodents and they get in there and eat the insulation and wires! You have to inspect the harness carefully when you have the intake off because you can't see it when it's all together. Seen this twice now.

SOURCE: Water Pump replacement and then PO332 code ~ knock sensor

Sounds like you have several problems. The P0332 sounds like you got your knock sensor wet and needs to be replaced. When you do make sure you replace the wire harness also and that you seal around both sensors. Also remove the back near fire wall foam under the intake mani to let the water that collects evap out.

SOURCE: i have an engine code PO332 knock sensor 2 circuit

The most likely cause of your code is a bad rear knock sensor. You should check the knock sensor wiring harness for corrosion. But if that checks out the sensor will have to be replaced. The knock sensor is under the intake manifold, although it's not too difficult to remove. Both knock sensors should be replaced along with the wiring harness, just because of labor involved in gaining access to the sensors. You could try clearing the code, it may stay off for a long time.

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

Hope this helps; just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Have a nice day and thanks for using FixYa.

I have a 04' Chev, 6.0L. Engine light came on, fault code came up PO332. I'm afraid the KS's are under the intake. Is there any way to test the KS to see if it is bad, or is there another problem that is...


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

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

Causes for P0332 DTC:
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- PCM or ECM failure.

Solutions:
- Repair or resecure the harness or connector.
- Replace the knock sensor.

Your best bet is to just replace the knock sensor for sensor 2 bank 2. Call Auto Zone with part number SU1282 this is the OEM replacement.

The knock sensor looks like this:
