This occurs as the detection tooth, linked to the timing rotor, moves to and fro the camshaft position sensor.Ĭonsequently, the MRE (magnetic resistance element) value changes and the engine’s ECU voltage is applied to the camshaft position sensor. The movement of the rotor affects the direction of the magnetic field radiated by the magnet in line with the position of the detection tooth position. The camshaft position sensor identifies camshaft rotation by using its sensor’s magnet. How does the camshaft position sensor work?
Thankfully, this article will be looking at some of the symptoms of a failed CMP sensor so that you can avoid these kinds of situations. So what happens when a camshaft sensor goes bad? Well, the situation might lead to potentially bad situations like your vehicle losing power in the middle of the highway. So by extension, your car’s CMP sensors play a crucial role in the efficiency of your vehicle’s engine and, ultimately, your driving experience. Armed with this information, the ECM can regulate the timing of the ignition and fuel injection. The camshaft is essentially a rod/shaft with protrusions that open and close certain valves in the engine.Ī functional camshaft sensor keeps tabs on the sequence of opening/closing of these valves and relays the information to the vehicles’ computer or engine control unit (ECU).
Why? Because the camshaft position sensor (CMP) monitors the rate at which the camshaft turns. It will help your driving experience a lot if you can recognize the symptoms of a bad camshaft position sensor.
