Most people get in their car and crank it without ever thinking about what it takes to make this process happen. A variety of different sensors and ignition parts will have to work in conjunction in order for a car to crank. The engine computer that the car has is in charge of making sure that all of the systems are working properly. The camshaft position sensor sends data back to the engine computer to tell it when to fire and when more fuel is needed. Each time the car is started, the camshaft position sensor will play a vital role.

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. The heat that is produced by the engine can be very harmful on electrical components. Without having a properly working camshaft position sensor, it will be very hard for a car to crank and run like it is supposed to.

If the camshaft position sensor is giving the engine computer the wrong readings, it can throw the whole spark process off. The signs that a crankshaft position sensor is in need of repairs are very noticeable and should be taken very seriously. Here are some of the things that you may notice when it comes time to change your camshaft position sensor:

  • The car struggles to start
  • The car will not accelerate like it is supposed to
  • The Check Engine Light is on
  • The cylinders of the engine are misfiring
  • The car does not idle properly

The last thing that any car owner wants is to drive a vehicle that is not running at full capacity. Having a damaged camshaft position sensor can be very harmful to the car and can make the driving conditions very unsafe. As soon as signs of repair are detected, you will have to take the time to get the sensor replaced by a professional mechanic.
