CYLINDER HEAD TEMPERATURE (CHT) SENSOR INSPECTION [MZI-3.7]

id0140c3889900

  Note
  • Do not reuse the CHT sensor, install a new sensor.

Resistance Inspection

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

2. Disconnect the CHT sensor connector. (See CYLINDER HEAD TEMPERATURE (CHT) SENSOR REMOVAL/INSTALLATION [MZI-3.7].)

3. Measure the resistance between CHT sensor terminals A and B.
