Question

What is the knock sensor circuit low in the 2002 Chevrolet Silverado 1500 4wd 5.3L?

Answer 1

HI there,

The knock sensor is there to help the computer deal with engine ping from unleaded fuel. If the knock sensor sends a signal to the computer, it will advance the timing to eliminate the fuel ping. IF you have a code for the sensor, in most cases the sensor itself is the issue.
