Before You Begin:
* Safety First: Disconnect the negative battery terminal to prevent electrical shorts.
* Gather Tools: You'll likely need a socket wrench set (metric), a ratchet, extensions, possibly a swivel, and possibly a small pry bar or flathead screwdriver (to help disconnect connectors).
* Identify the Sensor: Locate the camshaft position sensor. On most Concordes, it's typically located on the top of the engine near the camshaft, but its exact location depends on the engine type. Your repair manual will show you exactly where it is.
Procedure:
1. Access the Sensor: This will require removing various parts depending on the sensor's location. You might need to remove air intake components, electrical connectors, or even parts of the valve cover. Again, your repair manual will be crucial here.
2. Disconnect the Electrical Connector: Gently unplug the electrical connector from the sensor. Sometimes, a small pry bar or flathead screwdriver can help carefully separate the connector.
3. Remove the Sensor: Use the appropriate socket to remove the sensor from the engine block. It's usually held in place by a bolt. Be careful not to damage the sensor threads or the engine block.
4. Inspect the Sensor and Surroundings: Carefully inspect the old sensor for any damage. Also, inspect the area around the sensor for any debris or damage that might have contributed to the sensor failure.
5. Install the New Sensor: Carefully install the new camshaft position sensor, ensuring it's properly seated. Tighten the bolt to the manufacturer's specified torque (found in your repair manual). Do not overtighten.
6. Reconnect the Electrical Connector: Securely connect the electrical connector back onto the new sensor.
7. Reassemble: Reinstall any parts you removed to access the sensor.
8. Reconnect the Battery: Reconnect the negative battery terminal.
9. Start the Engine: Start the engine and check for any error codes using an OBD-II scanner. If codes appear, investigate further.
Important Considerations:
* Repair Manual: A repair manual specific to your 2004 Chrysler Concorde is highly recommended. It will have detailed diagrams, torque specifications, and step-by-step instructions tailored to your vehicle's specific engine.
* Engine Type: The exact location and procedure will differ slightly based on whether you have a 2.7L or 3.5L engine.
* Professional Help: If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic. Improper installation can cause further damage.
This information is for general guidance only. Always consult your vehicle's repair manual for precise instructions and safety precautions before attempting any repair. Incorrect installation can lead to further engine damage.
