Camshaft Position Sensor

 

Hello friends, welcome to all of you in another post, in this post, we will know what is camshaft position sensor and how it works, do you know that the camshaft position sensor is used in the car engine, in the engine plays the main role, it detects the position of the piston in the engine, the car starts only because of the camshaft

position sensor, if there is some fault in it, then the car does not start, let’s know about it in detail that these car engines How does it work and what are the defects in it and how to correct them

 

What is a camshaft position sensor

The camshaft position sensor is used in an automobile engine to measure the r.p.m and rotation and also detects the position of the piston and helps in starting the engine. Its mounted at a fixed distance above the flywheel. It goes but in many vehicles it is also installed on the damper flywheel pulley. also known as a flywheel sensor. The distance between the flywheel and the camshaft position sensor is fixed. If for some reason this distance is less, then the sensor stops working. Does

CAM sensor location

The CAM sensor is attached to the right or left side of the engine tappet above the flywheel.

What does the camshaft position sensor do?

As you all know that the function of a camshaft is to open and close the inlet and exhaust valves in the engine cylinder. CAM sensor measures the position and angle of a camshaft and sends the signal to the engine control model ie ECM which is detected by ECU voltage. What is the position of which cylinder in the engine according to that ECM decides the firing order in the engine that in which cylinder the fuel is to be supplied

and in which cylinder the spark is to be given? Three wires are used in the cam sensor, in which a positive, signal is used. , earth wire is used in which an ECM is also used, it sends the signal to ECM sensor which is about 5 volt and further cam sensor gives power to ECM, for information tells that CAM in petrol engine The sensor is used for the timing of the spark and in diesel engine it is used to give a pulse to the injector.

 

The CAM sensor is mounted on one side of the camshaft, and to operate the CAM sensor, circular teeth are cut on the camshaft. The reason is that when the cam rotates and this gap comes in front of the cam sensor, the

cam sensor generates different voltages, which signals the electronic control module (ECM) that one revolution of the camshaft has been completed, and due to this signal, the ECM Senses the position of the piston and generates the firing order of the engine

Also, let us tell you that if a regular signal is not coming on the ignition coil in a petrol engine, then the CAM sensor is checked, whereas if the injector plus is not coming in a diesel engine, then the CAM is also checked in that case. sensor is checked

 

 

Types of cam sensor

Let us know how many types of CAM sensors are there, for your information, let us tell you that there are two types of CAM sensors which are as follows

Two-wire cam sensor

Two wires are used in this type of CAM sensor, one is the ground wire and one is the signal wire. The current of the signal wire is required to be from 2.6v to 5v and the regularity of the ground wire is checked through a multimeter. goes

Three-wire cam sensor

As the name suggests, three wires are used in this, in which one wire is signal wire, ground wire, and a positive wire called reference voltage wire. In different vehicles, the voltage is different like signal wire. But there is 2.5v in some and 5v in some, similarly, power means on the reference wire, in some, it is 12v, in some it is 5v and there is also 2.5v in some, and the regularity of the ground wire is checked through a multimeter.
