Unlock and disconnect the electrical connector from the CMP sensor. Remove the CMP sensor mounting bolt and take out the CMP sensor. If you're reinstalling the old CMP sensor, scrape off the old spacer and install a new paper spacer. If you're installing a new CMP sensor, it will come with a new paper spacer.

Disconnect the cable from the negative battery terminal. Raise the front end of the vehicle and place it securely on jackstands. Disconnect the electrical connector from the CMP sensor. Remove the sensor mounting bolt and remove the CMP sensor. Inspect the CMP sensor 0-ring for cracks, tears, and other deterioration. If it's damaged, replace it. When installing the CMP sensor, apply a small dab of clean engine oil to the sensor 0-ring, then use a slight rocking motion to work the 0-ring into the sensor mounting bore. Do NOT use a twisting motion or you will damage the 0-ring. Make sure that the CMP sensor mounting flange is fully seated flat against the mounting surface around the sensor mounting hole. If the CMP sensor is not fully seated against its mounting surface, the sensor mounting tang will be damaged when the sensor mounting bolt is tightened to the specified torque. Installation is otherwise the reverse of removal. Be sure to tighten the CMP sensor mounting bolt to the torque. For Hemi engines, disconnect the electrical connector and remove the sensor mounting bolt to detach the CMP sensor from the timing chain cover. Remove the old CMP sensor 0-ring and inspect it for cracks, tears, and deterioration. If it's damaged, replace it. Apply a small dab of clean engine oil to the sensor 0-ring and use a slight rocking motion to work the 0-ring into the sensor mounting bore. Make sure that the CMP sensor mounting flange is fully seated flat against the mounting surface around the sensor mounting hole. If the CMP sensor is not fully seated against its mounting surface, the sensor mounting tang will be damaged when the sensor mounting bolt is tightened to the specified torque. Installation is otherwise the reverse of removal. Be sure to tighten the CMP sensor mounting bolt to the torque.

On 3.7L V6 engines, it is located at the front of the right-bank cylinder head.

Inspect the CMP sensor O-ring for any damage and replace if necessary. Apply a small amount of clean engine oil to the sensor O-ring and use a rocking motion to install it into the sensor mounting bore. Ensure that the CMP sensor mounting flange is fully seated against the mounting surface. Inspect the old CMP sensor O-ring for damage and replace if needed. Apply engine oil to the O-ring and install it using a rocking motion. Make sure the CMP sensor mounting flange is fully seated. Check the O-ring for damage and apply engine oil before reinstalling the sensor. The remaining installation steps are the reverse of removal.
