1. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZI 3.7 V6] .)
2. Remove the CMP sensor connector.
3. Measure the resistance between CMP sensor terminals A and B.

• If not within the specification, replace the CMP sensor. (See CAMSHAFT POSITION (CMP) SENSOR REMOVAL/INSTALLATION .)
