Steps:

  1. Locate the Sensor: The crank position sensor is typically located near the transmission bell housing on the passenger side of the engine.
  2. Disconnect the Battery: For safety, disconnect the negative terminal of the battery.
  3. Remove Components: Depending on your model, you may need to remove the radiator fan, intake manifold, or other components to access the sensor.
  4. Unplug the Sensor: Locate the plug for the crank position sensor and disconnect it.
  5. Remove the Sensor: Use the 5mm Allen wrench to remove the bolt that attaches the sensor to the engine case. Carefully pull the sensor out of its bracket.
  6. Install the New Sensor: Position the new sensor in place and secure it with the bolt.
  7. Reconnect the Plug: Plug the new sensor back into the engine loom.
  8. Reassemble Components: Reinstall any components you removed earlier, such as the intake manifold or radiator fan.
  9. Reconnect the Battery: Reconnect the negative terminal of the battery.

Testing:
After installation, it’s a good idea to test the new sensor to ensure it’s working properly. You can use an OBD-II scanner to check for any error codes, or perform an ohms test to verify the sensor’s resistance.
