Location of the Crankshaft Position Sensor
The crankshaft position sensor is located on the engine block, near the crankshaft. It is usually held in place by a single bolt. The sensor is a small, cylindrical device with a connector on one end.
Removing and Replacing the Crankshaft Position Sensor
1. Disconnect the negative battery terminal.
2. Locate the crankshaft position sensor on the engine block.
3. Remove the bolt that holds the sensor in place.
4. Disconnect the electrical connector from the sensor.
5. Remove the sensor from the engine block.
6. Install the new sensor in the reverse order of removal.
7. Tighten the bolt that holds the sensor in place.
8. Reconnect the electrical connector to the sensor.
9. Reconnect the negative battery terminal.
Testing the Crankshaft Position Sensor
1. Disconnect the electrical connector from the crankshaft position sensor.
2. Connect a multimeter to the sensor terminals.
3. Set the multimeter to the "resistance" setting.
4. The resistance reading should be between 500 and 1,000 ohms.
5. If the resistance reading is not within this range, the sensor is faulty and should be replaced.
Tips
- When replacing the crankshaft position sensor, be sure to use a new O-ring.
- The O-ring helps to seal the sensor and prevent oil leaks.
- If you are not comfortable replacing the crankshaft position sensor yourself, you can have it done by a qualified mechanic.
