Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet and extensions
* Torque wrench
* Possibly a swivel socket for easier access
* New camshaft position sensor (make sure it's the correct part for your engine)
* Shop rags or paper towels
* Possibly a small pry bar (if the sensor is stubborn)
Procedure:
1. Disconnect the Battery: This is crucial to prevent electrical shorts and potential damage. Disconnect the negative (-) terminal first.
2. Locate the CMP Sensor: The location varies slightly depending on the exact engine configuration, but it's typically on the top of the engine, near the back of the cylinder head, close to the camshaft. You might need a flashlight to see it clearly. Consult your repair manual for the precise location.
3. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the CMP sensor. Sometimes a small tab needs to be pressed to release the connector.
4. Remove the Sensor: The sensor is usually held in place by a single bolt. Use the appropriate socket to carefully remove this bolt. The sensor may be slightly stuck due to heat and grime. Gently wiggle or pry it out (if necessary, use a small pry bar, but be very careful not to damage the sensor or the engine).
5. Clean the Mounting Surface: Use a clean rag or paper towel to thoroughly clean the mounting surface on the engine block where the sensor was located. This will ensure a good seal for the new sensor.
6. Install the New Sensor: Carefully install the new camshaft position sensor into the mounting hole. Make sure it seats correctly.
7. Tighten the Bolt: Tighten the mounting bolt to the manufacturer's specified torque. This is very important; over-tightening can damage the sensor or the engine. Refer to your repair manual for the correct torque specification.
8. Reconnect the Electrical Connector: Securely plug the electrical connector back onto the new sensor.
9. Reconnect the Battery: Reconnect the negative (-) battery terminal.
10. Test the Vehicle: Start the engine and check for any error codes or unusual running conditions. Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs).
Important Considerations:
* Repair Manual: A repair manual specific to your 1997 Dodge Intrepid 3.3L is invaluable. It will have detailed diagrams, torque specifications, and other crucial information to ensure a successful repair.
* Safety: Work in a well-ventilated area. Be careful not to drop tools into the engine.
* Difficulty: While generally straightforward, access can be tight. You may need to use extensions and a swivel socket to reach the sensor easily.
* Professional Help: If you're not comfortable working on your car, consider taking it to a qualified mechanic.
This is a general guide, and the specific steps might vary slightly. Always prioritize safety and consult your repair manual for accurate instructions and torque specifications. Improper installation can lead to engine damage.
