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.

Barometric Pressure (Baro) Sensor Inspection
Voltage Inspection
NOTE:
Because the BARO sensor is integrated in the PCM, replacing the BARO sensor
includes replacement of the PCM.
1. Connect the M-MDS to the DLC?2.
2. Switch the ignition ON (engine off or on).
3. Verify that the BARO sensor output voltage (PID: BARO) is wi ...
