position sensor parts such as the crankshaft, can rightly be called a basic element in a car that operates on a par with the motor.The main task of the sensor of this type is the control of fuel injection, the fuel resources and the synchronization of the entire system ignition.That is why, if the details of this happening any failure, the machine simply can not "activated", and the motor is not included in the work.Also, as you move, the position sensor regulates the distribution of fuel, according to the driver of the engine speed, while continuing to synchronize the work of the motor.Such sensors can be of different types, they all operate according to different principles, which are primarily dependent on the model and the technical features of the machine.
most common - induction (or magnetic) sensor CKP.It operates due to the fact that it is formed around the magnetic field (hence the name of the machine) that interacts with the tooth timing.This type of sensor is also used by many drivers as a sensor indicative of the rate at which the car is moving.It is simple to use, highly resistant and is not affected by external factors.The second type of sensor - Hall effect, whose work is also based on the interaction of the teeth with a magnetic field.This sensor is often used as an indicator of the ignition distributor.A more advanced and relatively new kind of sensor - Optical, based in the work of which is the conversion of light flux in the voltage pulse.
position sensor, whatever it may be, is mounted to the circuit board by means of a long wire.He usually has the same packaging as any other car sensor.Therefore, problems with its mounting experience no one should.However, it should be noted that when mounting the crankshaft sensor is necessary to leave a gap of 1 to 1.5 mm between it and a toothed pulley, since otherwise the mechanism would not be able to form the required magnetic field, hence the position sensor will not operate.
damage the crankshaft position sensor may, if repairs are an amateur (and mistakenly been affected by the auto parts).Also, the reason of breakage may be foreign objects into the gap between the teeth and the sensor itself, which will stop its operation.Correct the situation can only replace it with a new device.It is therefore advisable to always have a spare version of the sensor that can be installed at any time.
order to advance to determine whether the defective position sensor in the car, you just need to connect it to an ohmmeter and measure the resistance.If his performance will range from 800 to 900 Ohms, then the mechanism is normal.Otherwise, such a sensor can not function, and every driver will immediately see the alarm.Typically, the error of the sensor is displayed as a code number 35, or 19 in the control buffer system.
