When did I replace the knock sensor on my Silverado?
So my ’01 Sierra’s SES light started coming on a few months ago so I pulled up the code and sure enough got the P0332 Knock Sensor code. I just replaced the knock sensors and harness less than a year and maybe 10K miles ago so I decided to clear the code and see if it came back.
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.
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.
