P0332 BUICK code

P0332 code definition If the knock sensor 2 circuit gives a low input signal, the PCM (powertrain control module) record a P0332 code and illuminate the Check Engine Light.

Can I drive with code P0332?

What Does Code P0332 Mean? Repair Urgency: Fix this code immediately (same day if possible) to avoid internal engine damage. Diagnosis: Pinging damages the lifetime of a vehicle’s engine and can affect its ability to run cleanly and efficiently.

What causes low input on knock sensor?

Diagnostic trouble code (DTC) P0327 stands for “Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor).” It is triggered when the powertrain control module (PCM) detects very low voltage readings from your vehicle’s primary knock sensor circuit.

How do you reset the knock sensor code?


Zitat von Youtube: You can now use the zeus app to clear the error. Code. And tap the rescan. Button one more time to make sure everything is fine with your vehicle.

What is a knock sensor 2 circuit?

It sends a message to the vehicle’s computer or powertrain control module (PCM) whenever it detects that one or more of the engine cylinders are knocking. The PCM then uses the information to adjust the ignition timing in order to prevent more knocking.

How do I fix error code P0332?

What repairs can fix the P0332 code?

  1. Replacing frayed or broken wires and connectors in the sensor circuit.
  2. Ensuring that the sensor and circuit are properly grounded.
  3. Replacing the knock sensor.
  4. Addressing the root cause in the EGR or cooling system.
  5. Replacing or reprogramming the PCM (rare)


What can cause a P0332 code?

A P0332 code gets logged when the PCM receives a reading from the knock sensor that is lower than the voltage specified by the manufacturer. To learn more about how the knock sensor works, you may read our explanation here. A knock sensor helps the powertrain control module (PCM) in monitoring engine “knocking.”

Can a vacuum leak cause a knock sensor code?

vacuum leak will cause lean condition, could be intermittent enough to cause a knock. Or you could have a bad knock sensor and this stuff. Either way you need to do a vacuum check, if it’s leaking, fix it, clear codes and see what happens.

Where is knock sensor located?

The knock sensor is located on the engine block, cylinder head, or intake manifold. Its senses vibrations caused by engine knock or detonation. When the ECM receives this signal, it retards the ignition timing, averting harm to the engine.

Can you unplug knock sensor?

Disconnecting it will not give you any direct data. If there is a real knock problem, you could end up damaging the engine. Second, if there is an issue with the knock sensor itself, you’d most likely get a trouble code of P0325, which is about a circuit malfunction.

What else can cause knock sensor code?

Faulty knock sensor. Circuit issues, such as damaged wiring and loose connections. Issues with the PCM (rare) Internal engine problems.

How much does a knock sensor replacement cost?

If you have a standard economy vehicle, you can expect to pay anywhere from $120 to $500 for replacing your knock sensor. The parts cost will be anywhere from $65 to $200, while the labor costs will be anywhere from $50 to $350. What is this? In most cases, the parts costs and labor costs will be about the same.
