Crankshaft Position (CKP) Sensor Removal/Installation

CAUTION:

When replacing the CKP 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.
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.

Turn the steering wheel to full right lock.
Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
Lift up the vehicle.
Perform the following procedure for easier access.
1. Remove the service hole cover (installed to front under cover No. 2) used to remove the oil filter. (See OIL FILTER REPLACEMENT .)
2. Remove the front splash shield (RH). (See SPLASH SHIELD REMOVAL/INSTALLATION .)
Disconnect the CKP sensor connector.
Remove the CKP sensor.
Install in the reverse order of removal.
