Mazda CX-5 Service & Repair Manual / Engine / Control / Knock Sensor (Ks)

Purpose/Function

Detects abnormal combustion in the cylinder as basic information for mainly determining the ignition timing.
Detects abnormal combustion in the combustion chamber and inputs it to the PCM as a knocking signal.

Construction

Installed on the cylinder block.
A piezoelectric element has been adopted as the detecting element for detecting abnormal combustion.

Operation

Inputs the signal, which fluctuates according to abnormal combustion, to the PCM.
