What is a camshaft position sensor?
There are two common types of camshaft position sensors – magnetic or inductive sensors and Hall effect sensors. Either sensor is pointed towards a gear-like section of the camshaft. As the individual teeth pass in front of the sensor, it produces a wave signal whose peaks and valleys correspond to the tips and roots of the teeth. By interpreting the frequency of the wave, the ECU can determine the rotational speed of the camshaft, as well as its position relative to the crankshaft.
How many camshaft sensors are there in a car?

How many camshafts does an economy engine have?
If you have an economy inline four cylinder engine, you probably have one camshaft and one position sensor. If you have a performance-oriented dual overhead camshaft design, you’ve got a camshaft for the intake valves and a separate one for the exhaust valves, each with its own position sensor.
What is a camshaft position sensor?
The camshaft position sensor (CMP) is used by the powertrain control module (PCM) to determine the position of the camshaft in relation to the crankshaft. The PCM uses this information for fuel injector control, and in some cases, ignition system control. There are two basic types of camshaft sensors: Hall effect and magnetic reluctance. The Hall effect design has three wires going to it: reference, signal and ground. The PCM sends a reference DC voltage to the camshaft sensor and the sensor sends a return signal back to the PCM in accordance with camshaft position. On the other hand, the magnetic reluctance sensor has two wires and creates its own AC voltage when it passes by a reluctor wheel inside the engine.
How to check camshaft position?

Install the sensor mounting screws and tighten them down using a wrench or ratchet and socket of of the appropriate size. Step 3: Reinstall the electrical connector.
How does a PCM work?
The PCM sends a reference DC voltage to the camshaft sensor and the sensor sends a return signal back to the PCM in accordance with camshaft position. On the other hand, the magnetic reluctance sensor has two wires and creates its own AC voltage when it passes by a reluctor wheel inside the engine .
