What happens if you don't fix your camshaft sensor?

If you ignore the symptoms listed here and your camshaft position sensor fails, your vehicle will not start. As a camshaft position sensor weakens, so does the data it transmits to the ECM. Eventually the data signal becomes so weak the ECM switches off fuel and spark delivery, and your engine will not start.

What controls camshaft position sensor?

The camshaft sensor works according to the Hall principle. It scans a ring gear on the camshaft. The rotation of the ring gear changes the Hall voltage of the Hall IC in the sensor head. This change in voltage is transmitted to the control unit and evaluated there in order to establish the required data.

What is the lifespan of a camshaft sensor?

The camshaft position sensor on a car is built to last as long as the car does, but in most cases it will have to be replaced well before that. Just like any other sensor or switch on a car, the camshaft position sensor will take a lot of abuse due to the heat that the engine produces.

Can low oil cause camshaft position sensor?

If the oil level is very low, to the point where the engine overheats however, yes. Excessive heat can cause a camshaft position sensor to fail. More likely in a "low oil level" situation is for the camshaft, lifters, or camshaft variable timing actuator to fail due to inadequate oil pressure and lubrication.

How many camshaft sensors are in a car?

Just like a four-cylinder engine, this engine comes with four camshafts. The camshaft position sensor in your vehicle tells the ECU which cylinder is firing. While the number can vary based on the age of your car, a new car should have four camshaft sensors, one for each camshaft.
