Tools You'll Likely Need:
* Socket wrench set (metric)
* Ratchet
* Extensions
* Possibly a swivel socket
* Torque wrench
* New camshaft position sensor (ensure it's the correct one for your vehicle)
* Penetrating oil (like PB Blaster)
* Rags or shop towels
* Safety glasses
Steps:
1. Safety First: Disconnect the negative battery terminal. This prevents accidental shorts and protects your vehicle's electronics.
2. Locate the Sensor: The CMP sensor is usually located on the engine block, near the camshaft. Consult your repair manual for the precise location. It's often a small sensor with a single electrical connector.
3. Access the Sensor: Depending on your engine and its location, you might need to remove some components to gain better access. This could include air intake components, hoses, or other parts that obstruct the sensor. Use penetrating oil on any stubborn bolts or connectors you might need to remove.
4. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the sensor. Sometimes a small tab needs to be pressed to release the connector.
5. Remove the Sensor: Use the appropriate socket to carefully remove the sensor from its mounting location. It's usually held in place by a bolt or two. Again, penetrating oil may be helpful if the sensor is stuck. Be gentle to avoid damaging the sensor or its mounting threads.
6. Install the New Sensor: Carefully install the new sensor into its mounting location. Hand-tighten it first, then use your torque wrench to tighten it to the manufacturer's specified torque. This is crucial to avoid damaging the sensor or its threads. Check your repair manual for the correct torque specification.
7. Reconnect the Electrical Connector: Carefully plug the electrical connector back onto the new sensor, ensuring it's securely seated.
8. Reinstall Components: Reinstall any components you removed earlier to access the sensor.
9. Reconnect the Battery: Reconnect the negative battery terminal.
10. Test the Vehicle: Start the engine and check for any trouble codes using an OBD-II scanner. A properly functioning sensor should allow the engine to start and run smoothly. If you still have problems, double-check your connections and ensure the new sensor is compatible with your vehicle.
Important Considerations:
* Repair Manual: This is crucial. A repair manual specific to your 1995 Ford Windstar will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Engine Type: The exact location and accessibility of the CMP sensor will differ slightly depending on whether you have a 3.0L or 3.8L engine. Your repair manual will clarify this.
* Cleanliness: Keep the area clean to prevent debris from entering the engine.
* Torque Specifications: Using the correct torque is essential to avoid damaging the sensor and its threads. Always consult your repair manual.
If you are not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Incorrect installation can lead to further engine damage.
