Crankshaft position (CKP) sensor and camshaft position (CMP) sensor [Skyactiv-G (with cylinder deactivation (e))]
Note:
– When replacing the CMP sensor, make sure there is no foreign matter on it such as metal shavings. If it is installed with foreign matter, the sensor output signal will malfunction resulting from fluctuation in magnetic flux and cause a deterioration in engine control.
– If foreign matter such as metal shaving adheres to the CKP sensor, it can cause abnormal output from the sensor because of flux turbulence, which can negatively affect the engine control. Verify that there is no foreign matter on the CKP sensor when replacing.
– Do not assemble the CKP sensor or change the installation position using any method other than the following. Otherwise, it could negatively affect engine control, such as the ignition timing and fuel injection.
