    Q:
    What is the function of a knock sensor in 1988 Chevrolet K1500 engine, and how does it reduce spark knock? Posted by Customer
    A:
    The knock sensor is responsible for detecting abnormal engine vibrations and reducing spark knock. It produces an AC output voltage that increases with the severity of the knock, which is then fed into the ECM/PCM to retard the timing.
