Mazda CX-5 Service & Repair Manual: 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.

Crankshaft Position (CKP) Sensor Removal/Installation
CAUTION:
When foreign material such as an iron chip is on the CKP sensor, it can cause
abnormal output from the sensor because of flux turbulence and adversely affect
the engine control. ...
