Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet
* Extensions
* Possibly a deep socket
* Torque wrench (highly recommended)
* Jack and jack stands (for easier access)
* Possibly a pry bar (depending on how stubborn the sensor is)
* Rags or shop towels
* New crankshaft position sensor (make sure you get the correct one for your engine)
General Steps:
1. Safety First: Disconnect the negative battery cable. This prevents accidental shorts and protects your electrical system.
2. Locate the Sensor: The CKP sensor is usually located on the engine block, near the crankshaft pulley. Its exact location will vary depending on the engine. Refer to your repair manual for the precise location. It's often a small sensor with a single wire connector.
3. Access the Sensor: You might need to remove some components to gain better access. This could involve removing the splash guard underneath the engine, or possibly even removing parts around the sensor itself. Your repair manual will show you what might need to be moved.
4. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the sensor. Some connectors may have a locking tab or clip that needs to be released.
5. Remove the Sensor: The sensor is usually held in place by a bolt or bolts. Use the appropriate socket to carefully remove the sensor. It might be slightly tight; use a gentle but firm approach. Avoid using excessive force to prevent damaging the sensor or the engine block. A pry bar *might* be needed but use it cautiously and only if absolutely necessary.
6. Clean the Area: Clean the mounting surface of the engine block where the sensor sits. Use a clean rag to remove any dirt, debris, or oil. This will ensure a good seal for the new sensor.
7. Install the New Sensor: Carefully install the new sensor into the mounting hole. Make sure it seats properly.
8. Tighten the Bolt(s): Tighten the bolt(s) to the manufacturer's specified torque. This information should be in your repair manual. Using a torque wrench is crucial to avoid stripping the threads or over-tightening the sensor.
9. Reconnect the Electrical Connector: Securely plug the electrical connector back onto the new sensor.
10. Reassemble: Reinstall any components you removed earlier to access the sensor.
11. Reconnect the Battery: Reconnect the negative battery cable.
12. Test: Start the engine and check for any error codes using an OBD-II scanner. If the check engine light is still on, there may be another issue, or the new sensor might be faulty.
Important Notes:
* Repair Manual: This is absolutely essential. Trying to replace the sensor without a repair manual specific to your 1994 Dodge Intrepid and its engine is strongly discouraged.
* Pictures: Take pictures before you start disconnecting things. This will help you remember how everything goes back together.
* Torque Specifications: Use a torque wrench and follow the torque specifications in your repair manual to avoid damaging the engine.
* Professional Help: If you're not comfortable working on your car, take it to a qualified mechanic. Improperly installing the sensor could cause further damage.
This guide provides a general overview. Always consult your vehicle's repair manual for precise instructions and torque specifications. Good luck!
