From the health of such an important part, as a camshaft sensor, the operation of all internal combustion engines depends, whether chainsaws, whether it has a car. Its role in the technique is great, because only it gives signals about when to serve, and when to adjust the engines fuel. But even such a detail may sometimes fail. I do not want specialists in this case, because it requires additional funds, I would like to do everything else on your own. How to check the camshaft sensor and fix it?
This is a tool that determines the timing site, located outside the angle, so that it mainly corresponded to the placement of the engine crankshaft. Management functions occur as follows: it produces signals to the control system through the distribution shaft (often called cam), by igniting or fuel injection.
He carries its job on the well-known Hall principle, so it is sometimes called no other than the Hall sensor. He changes the path of movement with the help of charge carriers - this is its main job. The fixation of this thing happens when the semiconductor of the magnetic field produces its intersection. Pulse streams created as a result of such actions are transmitted over other channels after a while. And thus the camshaft sensor determines the position of the rhythm of the piston compressing in each VTM cylinder.
Signs and causes of malfunction
People often ask themselves the question: how to check the camshaft sensor, and what should I do for this? In order to check the camshaft sensor successfully, you need to do several important steps.
- First you need to disassemble the engine, just not completely, but only partially. It is necessary in order to make it easier to get to it, and determine its position. The location is the location of the timing belt.
- If you find the camshaft sensor, take the multimeter, in order to perform its detailed check. Next, it will be necessary to separate all the wires, and instead, connect to the multimeter output channels, and press the resistance mode.
- Then it will be necessary to take any object from the metal and tell him at a not a short distance from this device. As such an item, turning well. If, with this procedure, the figures will not be changed in the indicator - this indicates its malfunction.
It is not necessary to upset immediately, often it happens because of the incorrect setting of the gap or when the sensor is contaminated. Therefore, it will need to be cleaned. Most often, this happens with such a domestic car as Lada Kalina. 
If he, it seems to be corrected, but these symptoms appear - most likely, its wiring is reversed. It also happens that it does not highlight numbers, and instead shows error codes - in this case, it will be much easier to detect the problem, and make a replacement immediately.
These were somewhat simple ways to check the camshaft sensor, which no difficulty make up.
Instructions for checking and replacing
In the case where the above methods failed to bring its condition to the norm, then this item is subject to replacement. In replacement, as well as in the inspection, there is nothing complicated, since the fastening of their camshaft occurs without adjusting the gap. Thanks to such a function, you can avoid errors when installing a new device. In case the clearance is regulated, it is necessary to comply with certain norms.
If you are not sure that the camshaft sensor replacement will be successful independently, take it to a special service center. There is a replacement with an oscilloscope. When the oscilloscope is started, there is a stability of data reading on various engine speeds. 
If you have an oscilloscope, and you are sure that you can make such a procedure - do. Just closely monitor the change of this that will show the oscilloscope. If it shows straight strips, and there are no spaces - it's good. Because only to remove the old one, but put a new one.
In principle, if you use this method, you need to take into account many points and features that the tester provides the replacement of this part of the camshaft successfully. Since if the indicator does not work, then according to the logic of things and the engine should not work. But the technique is a delicate matter, and sometimes she gives failures in work. If the sensor and embedded electrical appliances do not know the position location - they go to the emergency. And, while in a long time in such a state, the sensor fails.
