2000 silverado knock sensor issue


I think it not real probable that the cause of your knock sensor code is the result of bad gas. However, I suppose it IS possible. Most knock sensor codes are caused by engine mechanical problems like bad pully bearings, loose timing chains, broken valve springs, collapsed valve lifters, etc. that would cause a "knocking" or "tapping" in the engine.

The next most probable cause would be damaged knock sensor wiring. I have fixed many that have had damage from rodents getting into the engine compartment and chewing on the wires. Depending on which engine your Silverado is equipped with, the knock sensor could be mounted between the cylinder heads in the valley under the intake manifold. Mice like it under there.

Then again, it all depends on WHAT KIND of knock sensor code you are getting. For 2000 Silverado there are 3 possible knock sensor codes: P0325, P0327, P0332. The diagnostics (and possible causes) change depending on which code you have.

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:
