The easiest way to test for a camshaft sensor malfunction is to buy a code reader or take your car to a mechanic for testing.
A code reader will help you diagnose your car in your garage. Once you receive a code, you can do some research and figure out your next move. The most common code related to camshaft sensor malfunction is P0340, which refers to a circuit malfunction in the sensor. Once you have that information, you can take your car to a mechanic to fix it.
