Car have intelligent systems that control different aspects such as temperature, coolant levels, oil pressure, emission levels and so much more.
So, There are many different sensors in your car that need to function properly and together to keep you going down the road.
As a result, A signal that’s out of normal parameters from any sensors can be enough to trigger a trouble code in the engine computer and illuminate the “check engine” light.

So, Most car sensors pretty much do the same thing. Because, They all change electrical resistance that the (PCM) reads as a change in voltage.
So, Sensors monitor all the key functions necessary to manage ignition timing, fuel delivery, emission controls, transmission shifting, cruise control, engine torque reduction (if the vehicle has anti-lock brakes with traction control) and charging output of the alternator.
