Do you have information about camshaft sensor position , if not, then you have come to the right place, today we will give you complete information about this sensor.
We know that you have to know about the camshaft sensor now because there is a problem related to the camshaft sensor in your car, which is bothering you a lot.
And you want to know the complete information of camshaft sensor, you do not have to worry, today we will give you complete information about camshaft sensor position.
To overcome the problem related to this sensor, you have to understand this sensor very well, what is it, how it works, why it is bad, how it can be checked, know about all these
what is camshaft position sensor
The camshaft sensor helps in starting the car, there is a camshaft in the head inside the engine, which works to press the valve, there is a cover on that camshaft, and in that cover, the camshaft sensor is on the camshaft.
There is a magnet inside the camshaft sensor which produces a signal when the camshaft rotates and sends that signal to the ecu which is used to detect the position of the piston.
Earlier there was only one camshaft sensor in the engine and only one camshaft sensor used to send signals to the ecu but according to the changing times, since the bs6 car has come, two 2 camshaft sensors are being used in the engine.
The first sensor is mounted on the top of the camshaft cover and the second sensor is mounted on the right side camshaft in the timing cover and both of these camshaft sensors send signals to the ecu, now let’s know about its working.
working of camshaft sensor
As we have told you that the engine has a camshaft which is fitted in the main head and the main function of the camshaft is to open and close the intake and outlet valves.
When we start the car, the crankshaft rotates and the crankshaft has timing chain, connecting rods and pistons, as the engine rotates, the pistons work as well as the timing chain rotates.
This timing chain is attached to the camshaft, the valve of the cylinder whose piston comes to the top, the camshaft closes and opens with the help of the timing chain, but there is a sensor for the signal of all these.
The position of the piston cannot be detected without the sensor, for that only the camshaft sensor has been installed, the camshaft sensor can easily detect the position of all the pistons.
When we start the car, the piston of the first cylinder starts coming to the top, at that time the camshaft sensor generates a signal and detects that the piston top is about to come.
The camshaft sensor sends that signal to the ecu, according to the signal received by the ecu, it is known that the piston top is about to come, then the ecu sends the signal to the injector based on that signal.
As soon as the injector receives the signal, the injector sprays fuel over the piston and the piston comes to the top, and at the same time the spark plug does a blast, which ignites the fuel, and the piston moves down, and the camshaft opens the exhaust valve, which occurs during the blast. smoke goes out
In this way the camshaft sensor detects the position of all the pistons and sends a signal to the ecu to supply fuel to the pistons and the engine works.
If the camshaft sensor is bad then the camshaft will keep rotating but the camshaft sensor will not be able to generate any kind of signal which will not be signaled to the ecu and the car will not start.
camshaft sensor position
You have come to know how the camshaft sensor works, but you will not have complete information about where this sensor is installed.
You will be getting to see two photos above, in one you are getting to see the big sensor and in the other you will be getting to see the small sensor.
The first big sensor is the camshaft sensor, which is fitted in the timing cover, which is connected to the camshaft inside, similarly, you can see the second small sensor fitted in the top cover.
The camshaft is fitted under this cover and the camshaft sensor is fitted in the cover on top of that camshaft, with the help of a ten number bolt, the camshaft sensor position is at both these places.
In any company’s car, the camshaft sensor is installed in the camshaft cover, then it can be in the right side or left side of the cover and now the camshaft sensor is also being seen in the timing cover.
symptoms of bad camshaft position sensor
When the camshaft sensor of your car is bad then many different symptoms are seen in your car which are as follows
(1) . check engine light come on
If there is a problem with the camshaft sensor or if it is damaged, the check engine warning light turns on in the dashboard of the car. This warning light means that there is a problem with the sensor of your car and get the car scanned and the problem removed.
(2) . very hard starting
Whenever the camshaft sensor is bad or there is a problem in it, then the problem of hard starting starts to arise in the car, the car is self-locked, but after a lot of cranking, the car starts or many times many self-locks have to be applied after that. starts up
(3) . low pickup
When the camshaft sensor is damaged, the signal is broken due to which there is a problem of low pickup because when the camshaft sensor is damaged, the signal to the ecm stops, due to which the position of the piston is not detected and there is a problem of low pickup.
(4) . bad mileage
Due to camshaft sensor, you will face the problem of bad mileage in your car because when the signal of camshaft sensor is broken by ecm, ecm supplies fuel according to its wish, many times it does not, due to which the mileage goes down.
(5) . misfiring
You see the problem of misfiring in the car after the camshaft sensor is damaged, in this the engine of your car starts shaking, which we call vibration, inside the car, a lot of vibration is felt in the cabin because the cylinder does not work properly due to not getting the right fuel. do not do which leads to misfiring
(6) . smoke problem
After a problem with the camshaft sensor, you can see smoke from the exhaust of the car because when the ecm supplies wrong fuel after the signal is broken, the fuel in the cylinder does not burn properly, due to which smoke comes out from the exhaust.
(7) . car not start
It has been seen in some cars that after the camshaft sensor is damaged, the car stops starting because the ecm stops supplying fuel to the injector, so if your car does not start, then the camshaft sensor can be the main reason. get checked
These are some of the main symptoms that appear when the camshaft sensor is bad.
causes of camshaft sensor failure
There are some reasons for the camshaft sensor being damaged or the problem in it, about which you will get to see below.
(1) . damage sensor
Damage to the camshaft sensor is one of the main reasons for damage to the camshaft sensor, if for some reason the camshaft sensor gets hurt, such as in an accident, the camshaft sensor gets hit many times, due to which it gets damaged and the signal breaks.
(2) . crack camshaft sensor
The second biggest reason for the failure of the camshaft sensor is the crack of the camshaft sensor, due to which its magnet is destroyed and it is unable to generate the signal, many times the camshaft sensor gets damaged due to wiring shot.
(3) . damage ecu/ecm
If there is a problem in the ecu, there are small parts inside the ecu, if the part of the camshaft sensor gets damaged, then the ecm does not send the signal further, due to which the signal of the camshaft sensor is broken and the problem related to the camshaft sensor. comes
(4) . crack ecu connector and camshaft sensor wire
If there is a problem with the wiring of your car, such as if the camshaft sensor wire breaks somewhere or the connector of the ecm becomes loose, then also the problem related to the camshaft sensor can be seen.
These are some of the main reasons for the problem in the camshaft sensor.

function of camshaft sensor
The main functions of camshaft sensor are as follows
(1) . helps start the engine
The main function of the camshaft sensor is to start the engine at the right time, fuel has to be supplied inside all the piston cylinders at the right time and the information about the rotation of the camshaft has to be given to the ecu.
(2) . Beneficial for good mileage
The camshaft sensor is also used for good mileage because the camshaft sensor sends a signal to the ecm by detecting the engine rotation speed and the ecm supplies the right amount of air and fuel over all the pistons.
how to check camshaft sensor
You can easily check camshaft sensor, we will tell you how to check 2 pin camshaft sensor and 3 pin camshaft sensor
(1) . How to check 2 pin camshaft sensor
In 2 pin camshaft sensor, you will get to see 2 wires, out of which one wire is ground and the other wire is of signal, for this you will need a multimeter.
You have to take a multimeter and set it on continuity, after that you have to ground the black wire of the multimeter and in the red wire you have to put it in the grounded wire.
When you do this, a beep sound will be heard from the multimeter, it means that the ground wire is fine, after that you have to set the multimeter to signal 20.
After that black wire ground of multimeter has to be given and red wire has to be applied in signal and 2.5v – -5v has to be checked if it is coming then the sensor is fine
(2). How to check 3 pin camshaft sensor
In 3 pin camshaft sensor you get to see 3 wires, one wire is ground, second wire is positive and third is signal wire.
In positive wire you get to see 12 – 5 – -2.5+ and on signal wire you get to see 2.5 — 5v+ and ground comes in third wire, continuity comes in this wire
camshaft sensor fault code
When the car is scanned after a problem with the camshaft sensor, some fault codes appear, which are very important to check.
(1) . p0340 camshaft sensor no signal
(2) . p0341 camshaft sensor wrong signal
(3) . p0342 camshaft sensor a circuit low
(4) . p0343 camshaft sensor a circuit high
(5) . p0344 camshaft sensor a , sensor a circuit intermittent
Whenever there is a problem related to camshaft sensor in your car, then you get to see the fault code according to the problem, according to which you can fix the problem, all the codes mentioned above can also change in different cars, but they mean is the same
diagram of camshaft position sensor
You are getting to see the head in the photo above, it has a camshaft on the top with the help of some bolts and a pulley is fitted at the beginning of the camshaft, a timing belt is fitted on it.
