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. ...

Steering Angle Sensor
Purpose, Function
The steering angle sensor outputs the steering angle and steering angle reference
point during the period which the EPS control module performs initial learning
(approx. 1 min period).
Construction

Catalytic Converter
Purpose, Function
Purifies contaminants in the exhaust gas by utilizing the chemical reactions
of the three-way catalytic converter.
A WU-TWC and a TWC have been adopted.
WU-TWC
The three-way catalyst is integrated with the exhaust manifold.
Because the c ...
