Visual Inspection

1. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].)

2. Remove the following parts for easier access:

  1. HO2S (LH) (See HEATED OXYGEN SENSOR (HO2S) REMOVAL/INSTALLATION [MZI-3.7].)
  2. WU-TWC (LH) bracket (L type) (See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)
  3. WU-TWC (LH) (See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

3. Remove the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZI-3.7].)

4. Verify that there are no metal shavings on the CKP sensor.

  • If there is a malfunction, remove any metal shavings that are adhering.

Resistance Inspection

1. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZI-3.7].)

2. Remove the following parts for easier access:

  1. HO2S (LH) (See HEATED OXYGEN SENSOR (HO2S) REMOVAL/INSTALLATION [MZI-3.7].)
  2. WU-TWC (LH) bracket (L type) (See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)
  3. WU-TWC (LH) (See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

3. Remove the CKP sensor connector. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [MZI-3.7].)

4. Measure the resistance between CKP sensor terminals A and B.
