["NTK Ignition Knock (Detonation) Sensor"]
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.
