1. Disconnect the battery. This will prevent any electrical shock while you are working on the sensor.
2. Locate the crankshaft sensor. The crankshaft sensor is located on the front of the engine, near the oil pan. It is a small, cylindrical sensor with a wire connector attached to it.
3. Remove the sensor mounting bolts. There are two bolts that hold the crankshaft sensor in place. Use a wrench to loosen and remove these bolts.
4. Disconnect the sensor wire connector. Once the mounting bolts are removed, you can disconnect the sensor wire connector.
5. Remove the sensor. Once the wire connector is disconnected, you can remove the sensor from the engine.
6. Install the new sensor. Place the new sensor in the same position as the old sensor. Thread the mounting bolts into the engine and tighten them securely.
7. Reconnect the sensor wire connector. Reconnect the sensor wire connector to the sensor.
8. Reconnect the battery. Reconnect the battery to the vehicle.
The crankshaft sensor is now replaced and the engine should start and run properly.
