2 Pc Best Quality /Performance Knock Sensor for Toyota Lexus 8915-12040 5S2249 SU4040 KS81 RAKS1031

Description

The knock sensor is located on the engine block, cylinder head or intake manifold. This is because its function is to sense vibrations caused by engine knock or detonation. The PCM uses this signal to alter the ignition timing and prevent detonation. It will compare this information with its preset tables to identify a valid knock or ping. If a ping is sensed, it will retard the ignition timing to protect the engine from this damaging pre-ignition. The knock sensor is located on the engine block, cylinder head or intake manifold.
