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.

Purpose
The pressure sensor determines at an earlier stage whether to detonate the
air bag on the side of the vehicle (around front door) receiving an impact.
This is for improved accuracy of the side air bag operation (deployment).
Function
When the vehicle is involved in ...
