What are the codes for a knock sensor?

Here is a photo of one knock sensor: If the knock sensor or associated wiring has failed or broken, you may see some of the following knock sensor related automotive repair trouble codes: P0325 – P0326 – P0327 – P0328 – P0329 – P0330 – P0331 – P0332 – P0333 – P0334

How much does it cost to replace a knock sensor?

You can always just put it back together and run it while you wait for any parts or supplies. The harness might be easily repairable. It’s certainly not a quick disassemble/re-assemble job. I think it bills at about 5 hours. A new harness is inexpensive at ~$30. I’ll probably just buy the harness and bypass hose to have on hand.

Is there a code for bad speed sensor?

There’s also no code that says “bad speed sensor.” http://www.obd-codes.com/p0500 But you also need to sort out the knock sensor issue – knocking is very bad for the engine. The faulty knock sensor will not cause the Check Engine light to come on nor will it cause the driveability symptoms you describe.

Can a faulty knock sensor cause a check engine light to come on?

The faulty knock sensor will not cause the Check Engine light to come on nor will it cause the driveability symptoms you describe. The cost for knock sensor replacement is that high because it involves removing the upper and lower intake manifolds for access.

What are the codes for the knock sensor?

Eventually this turns on the check engine light and sets the codes P0332 and P0327. Note that often either one or the other code will set. Regardless if one or both codes are set, not only should the two original knock sensors be replaced, but you should also replace the harness.

Is there a knock sensor problem on my Hummer?

In fact, if you have a 4.8 L 5.3 L or 6.0 L in any General Motors vehicle, including a Hummer or Pontiac, you will probably run into a check engine light indicating a defective knock sensor at some point.The check engine light registering a code P0332 or a P0327 is often the first sign you have this common problem.

Why is the knock sensor on my car only one wire?

If drive around with the check engine light on when a code P0332 or a P0327 is set in the computer memory, engine damage could occur. To me the most interesting part about the knock sensor is that it only has one wire going to it. The reason for this is the sensor generates its own voltage and is case grounded.

Since this problem is intermittent, it may take some time for road testing to properly diagnose. Remember, whenever the guy is working on your car, the clock is ticking at $90/hour (or whatever the going rate is where you are).
