It is important to clean the space around the sensor before you work on the CMP. If necessary, take off the engine sight shield, and after that, pull off the CMP sensor electrical connector. After that, unscrew the CMP sensor bolt and take the CMP sensor away. After putting the CMP sensor in place, use the CMP sensor bolt and tighten it to 25 N.m (18 lb ft), following Service Precautions for fasteners. Make sure to put the electrical connector for the CMP sensor back on, and the sight shield as required.
