Mazda CX-5 Service & Repair Manual: Camshaft Position (CMP) Sensor
Purpose/Function
-
Detects the camshaft speed as basic information for mainly determining the fuel injection timing and ignition timing.
-
Detects the camshaft speed and inputs it to the PCM as a CMP signal.
Construction
Intake CMP sensor
-
Installed on the cylinder head.
-
A GMR element has been adopted as the detecting element for detecting the intake camshaft speed.
Exhaust CMP sensor
-
Installed on the rear housing.
-
A GMR element has been adopted as the detecting element for detecting the exhaust camshaft speed.
Operation
-
Inputs the signal, which fluctuates according to the camshaft speed, to the PCM.
