How do you test cam sensor on 2002 Jeep liberty?

To test the camshaft position sensor on a 2002 Jeep Liberty, first locate the sensor, typically positioned near the engine's cylinder head. Use a multimeter to check for resistance by disconnecting the sensor's electrical connector and measuring the resistance between the terminals; it should fall within the manufacturer's specified range. Additionally, you can check for proper voltage supply to the sensor while the engine is running. If the readings are outside the specified range, or if the sensor is not producing a signal when the engine is cranked, it may need replacement.
