Mazda CX-5 Service & Repair Manual: Crankshaft Position (CKP) Sensor

Mazda CX-5 Service & Repair Manual / Engine / Engine Assembly / Crank, Balancer / Crankshaft Position (CKP) Sensor

Purpose/Function

Detects the crankshaft speed as basic information for mainly determining the fuel injection timing and ignition timing.
Detects the crankshaft speed and inputs it to the PCM as a CKP signal.

Construction

Installed on the side of the cylinder block (right side).
An MR (Magnetic Resistance) element has been adopted as the detecting element for detecting the crankshaft speed.

Operation

Inputs the signal, which fluctuates according to the crankshaft speed, to the PCM.

CKP sensor characteristic

Fail-safe


DTC No.	Fail-safe function
P0335:00	Stops the fuel injection. Stops the ignition.
