Probably, every motorist was in a situation where one fine day after turning the ignition key his "iron friend" completely refused to start. Oddly enough, but the reason for this can be not only a seated battery or a burned-out starter, but also a crankshaft sensor. If its body was deformed or the whole structure moved a couple of millimeters to the side, the replacement of this part is required.
And when the garage neighbors tell you that replacing this element is a rather complicated operation that requires special expensive tools, do not believe these words. You can change the crankshaft sensor yourself. Moreover, doing this kind of work, you save a lot of money on the services of service stations and at the same time gain experience in this area. Therefore, today's article will be important for all motorists.
Why does the crankshaft sensor fail?
Based on the testimony of this part, the injection system synchronizes the operation of nozzles and ignition. Therefore, injection is not possible without this part. And when the crankshaft sensor stops working, interruptions begin in the engine. Therefore, no modern car can do without this small spare part. And in order to prevent this malfunction, you need to regularly check the status of the sensor. But when the symptoms began to be translated into reality, the driver had no choice but to replace him urgently.
How to remove the crankshaft sensor?
Just note that this procedure can be performed without a special lift. So, let's get to work. First, unscrew the sensor mounting bolts that connect it to the gearbox. In fact, in order to remove the necessary spare part, we need only this stage. But since this part is located in a very inaccessible place (almost on the bottom), we will have to sweat a lot. For work, we need an extension cord, a key for 11 millimeters and, of course, good lighting. It is important that the length of the first part is about 80-90 centimeters. If these tools are available, unscrew the bolts. But before you remove the crankshaft sensor, pay special attention to the rubber lining. If in the future it will be poorly installed or its clearance will be at least 1 millimeter, all the readings of the measuring device will be inaccurate, and, accordingly, the engine will work intermittently. It’s best to mark this part and put it in a separate place. The entire process of dismantling the spare part, bolts and lining should be performed with great care. This item does not like rough treatment.
Next, take a new crankshaft sensor and mount it in place of the old one. During installation, this element should be lowered through the entire engine compartment, so as not to catch the connector from the installed element on top. Then do not forget about the gasket. We mount it carefully and check the integrity of the structure. It is important that the gap between it and the sensor is minimal or completely absent. After that, we attach the wires to the part, connect all the connectors and start the ignition. If you did everything right, be sure - the engine will start from a half-turn.
