How to check the crankshaft sensor? vehicle history reports Every car owner well aware how important car for performance crankshaft position sensor (DPKV). Also, it is sometimes due to the fact that it can be synchronized operation of the electronic engine vehicle history reports control unit, this device is called synchronization sensor.
In the event of damage described in the sensor, it is impossible to start the engine or else in his work will be a failure that can lead to a complete stop (decrease power failures in turns). Also, this sensor is responsible for synchronizing the fuel supply by turning the key in the ignition. Signs of malfunction crankshaft sensor: marked decrease its dynamic characteristics in the process of movement of the machine (of course, in this issue, there are several reasons, but that this failure will inform the controller that will fix the problem and kindle check engine in the instrument panel). motor spontaneously decreases vehicle history reports or increases the speed; Idling is no stability in turns; occurrence of knocking in the engine during vehicle history reports dynamic loading; inability to start the engine.
Initially you need for yourself to understand how to perform a quality check of its efficiency and to be absolutely sure that everything is in order. Why such a check is always necessary to carry out the first one?
Everything is quite simple. Despite the fact that in most cars this sensor is not located in the most convenient location, it checks of takes you very little time and resources. After a check you will be absolutely clear, it is necessary to replace the sensor. How to verify the crankshaft sensor?
Check the accuracy of the sensor (DPKV) in several ways. For each option, you will need to use certain devices. The most commonly used three main approaches to health check speed sensor, crankshaft, look at them.
Based on the advice of professionals, always before checking sensor, crankshaft must be removed, do not forget, vehicle history reports with the label for its original location on the engine. It is understood that after the removal is necessary to make a visual inspection of the sensor. The results of visual inspection to detect damage to enable it to understand the state of the contact pads, the core contacts themselves. Contamination vehicle history reports should be removed using alcohol or benzine. Do crankshaft sensor vehicle history reports must be clean contacts. The dismantling process is necessary to set the distance from the sensor to the drive core synchronization. It should vehicle history reports vary from 0.6 mm to 1.5 mm. In the absence of any problems, you can move on to finding hidden in the electric circuit of the device.
Such verification tester (multimeter) is to test the resistance of the coil of the inductive sensor. Since the affected coil of the transmitter will appear primarily on the resistance. Set the desired range and check the probes on the findings. Such verification is the most elementary and simple, this can not give a 100% certainty that the diagnosis sensor placed correctly.
If you want to be sure in their actions, before vehicle history reports starting work read the instructions carefully to your car. When you have received, measurement values do not correspond to the declared interval, it is necessary to replace the crankshaft speed sensor.
The second approach is to verify the functionality of DPKV is more time consuming vehicle history reports and to carry it out you need to have more instruments: megger; vehicle history reports power transformer; inductance meter; voltmeter (preferably digital);
Analyzing all derived from the measurement data, indicators, you will be able to draw conclusions about performance crankshaft sensor or the need to carry out its replacement. vehicle history reports Do not forget to install in place of the new or old appliance, carefully guided by the marks left when you dismantle, vehicle history reports mindful of the need for a distance of 0.5-1.5 mm from the core to the disk synchronization.
The third method of diagnosing a speed sensor, crankshaft is the most accurate and is used at professional stations. It requires the presence of an oscilloscope and programs. When it is not necessary
