Visual inspection

1.  Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

2.  Disconnect the negative battery cable.

3.  Remove the aerodynamic under cover No.2 and splash shield as a single unit. (See AERODYNAMIC UNDER COVER NO.2 REMOVAL/INSTALLATION.) (See SPLASH SHIELD REMOVAL/INSTALLATION.)

4.  Disconnect the CKP sensor connector.

5.  Remove the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

6.  Verify that there are no metal shavings on the sensor.

•  Remove any metal shavings that are adhering.


Air Gap Inspection

1.  Verify that the CKP sensor is securely installed.

2.  Using a thickness gauge, measure the air gap between the plate projections at the back of crankshaft pulley and the CKP sensor.

•  If not within the specification, inspect the plate projections for cracks or bending.
―  If there is any malfunction, replace the crankshaft pulley. (See FRONT OIL SEAL REPLACEMENT [MZR 2.0 DISI i-stop].)

0.5—1.5 mm {0.02—0.05 in}


Voltage Inspection

1.  Idle the engine.

2.  Measure the CKP sensor output wave pattern using an oscilloscope. (See PCM INSPECTION [MZR 2.0 DISI i-stop])

•  If not within the specification, replace the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)
