Knock Sensor - Standard Ign Parts KS342

The knock sensor detects the mechanical vibration signature of engine knock or detonation and signals the ECM to retard ignition timing to prevent engine damage. Signs of failure include: a check engine light with a knock sensor code, a reduction in power because the ECM has put the engine into a conservative timing map, or audible pinging under load that the ECM is no longer correcting for. Replace a faulty knock sensor to protect the engine and restore full performance.
