Knock Sensor (KS) PCM Input
Knock Sensor (KS) PCM InputThe knock sensor (KS) system is comprised of a
knock sensor and the PCM. The PCM monitors the
KS signals to determine when engine detonation occurs. When a knock sensor detects detonation, the PCM retards the spark timing to reduce detonation. Timing may also be retarded because of excessive mechanical engine or transmission noise.
