Tools You'll Likely Need:
* Socket set: Including the correct size for the CKP sensor (usually a 7mm, 8mm, or 10mm). Check your repair manual for the exact size.
* Wrench: Possibly needed depending on the sensor's mounting.
* Ratchet: To make socket work easier.
* Extension: Possibly needed for better access to the sensor.
* Penetrating oil (PB Blaster or similar): Helps loosen stubborn bolts.
* Shop rags or paper towels: To clean up any spilled oil.
* New crankshaft position sensor: Ensure you get the correct part for your specific vehicle. The part number should be on the old sensor.
* Torque wrench (optional but recommended): To tighten the sensor to the correct specification. Your repair manual will specify this torque.
Procedure:
1. Safety First: Disconnect the negative terminal of your car battery before starting any work.
2. Locate the Sensor: The CKP sensor is typically located on the engine block near the crankshaft pulley, often towards the front of the engine. Consult your repair manual for its exact location. It's usually a small, cylindrical sensor with a single wire connector.
3. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the CKP sensor. Sometimes a small tab needs to be pressed to release the connector.
4. Remove the Sensor: Use the appropriate socket and ratchet (and possibly an extension) to carefully remove the CKP sensor from its mounting location. The sensor may be held in place by a bolt or simply pressed in. If it's stubborn, apply penetrating oil and allow it to soak for a few minutes before attempting to remove it again. Be gentle to avoid damaging the threads or the sensor itself.
5. Clean the Area: Use a clean rag or paper towel to clean the mounting area of any debris or oil.
6. Install the New Sensor: Carefully install the new CKP sensor into its mounting location. If it's threaded, screw it in by hand until it's snug, then use the socket and ratchet to tighten it to the correct torque specification (found in your repair manual). If it's press-fit, ensure it's seated firmly.
7. Reconnect the Electrical Connector: Securely reconnect the electrical connector to the new CKP sensor.
8. Reconnect the Battery: Reconnect the negative battery terminal.
9. Start the Engine: Start your engine and check for any error codes or unusual engine operation. If the check engine light comes on, have the codes scanned to determine if the replacement was successful or if another issue exists.
Important Considerations:
* Repair Manual: A factory service manual is invaluable for this procedure. It provides diagrams, torque specifications, and detailed step-by-step instructions specific to your vehicle.
* Access: Access to the CKP sensor on the Intrigue can be limited. You might need to remove other components to get better access. Refer to your repair manual for guidance on this.
* Torque Specification: Tightening the sensor too much can damage it or the threads. Using a torque wrench is essential to prevent this.
* Engine Timing: While unlikely, improperly installing the CKP sensor could potentially affect engine timing. If you experience any problems after the replacement, consult a mechanic.
This guide provides general instructions. Always refer to your vehicle's repair manual for precise instructions and safety precautions specific to your 1999 Oldsmobile Intrigue 3.5L. If you're not comfortable performing this repair yourself, it's best to consult a qualified mechanic.
