1. What functions does the engine tree sensor have?

The engine tree positioning sensor is designed to synchronize the ignition system and functioning of fuel injectors in a petrol injection engine. Consequently, its failure will lead to the speed or delay of ignition. This leads to the incomplete combustion of the fuel mixture, the unstable engine operation or even the complete malfunction.

The position of the location of the engine tree it is also called Synchronization sensorSince it allows electronic control (controller) to synchronize its activity with the gas engine distribution mechanism, thus offering the formation of signals to the Auk.

When the engine tree sensor sends the signals to the Auk, it specifies the position of the elbow tree. Also with the signal reports the rotation direction of the tree indicating its speed.

It should be remembered that on different cars both the device itself and some sensor functions may differ. It depends on the type of type (sensor) installed.

So the sensors can be:

• Magnetic
• Hall effect sensors
• Optical sensors

2. Where is the engine tree sensor?

Identify the position of the engine tree position without having the slightest idea how it appears is difficult. The position of the sensor can be determined as follows:

• Near the generator training scripts – It is found in a special support. The remote tooth sensor and the toothed light are established using appropriate Sabes. (Distance) must be 1 millimeter.

• The sensor body is almost identical to those of other sensors, but stands out for the coupling connector on the automotive network, which has a long wire. The length of the wire (at least 70 cm) allows you to neutralize, at least partial, disadvantage to place the sensor in the engine compartment.

Examples of position of the motor tree sensor on different vehicles:

• In vehicles with Vaz injection 2110, 2111, 2121 etc. The sensor is located exactly in the area of ​​the generator belt pulley – on the oil pump lid.
• To the Daewoo Nexia cars – it depends on the type of engine:

– at the F16MF- compared to the training ring (disc), at the rear end of the engine tree;

-I A15 MF, G15MF and A15SMS engines are compared to the training wheel on the tree pulleys;

• To Dacia Logan (1.4 and 1.6 liter engines) – is located at the bottom right in the cylindrical blocking area. It can be easily identified by two assembly holes.
• A HYUNDAI – The sensor is under the coverage of the distribution belt, in the lower part, in the area of ​​the balancing cylinder.

If it is not a question of identifying the engine tree sensor on your car, you need to consult the technical documentation for specific change or call an authorized service.

3. Senomas sensor defective pulse tree

When the engine tree sensor is defective you will be able to observe a series of specific symptoms.

Usually the most common are:

• Decreased engine power: when driving with a loaded car or digs a slope you can have the impression that the «does not pull» engine;
• The speed of the engine «floats» – the car is both destroyed in walking
• «Bankruptcy» – when the adhesion pedal is pressed it has no speed;
• During the dynamic load, the detonation in the engine takes place.
• A complete defect of the sensor leads to the impossibility of starting the engine.
• An error code P0336 is displayed.

Of course, these symptoms can mask other problems, so you can take a look Here.

4. Methods for checking the engine tree sensor

There are three methods to control the engine tree sensor:

• By checking the resistance with Ohmetro: this is the simplest verification method, but it does not offer a 100%guarantee. The resistance of the educator is measured with it. This can be done simply by touching the multimeter test cables in the coil cables. Polarity in this case does not matter. Usually the resistance of most coils is between 550 and 750 ohm.
• The control of the value of the home – is based on the ability of modern multimeters to measure induction. This method is more complex and requires use:

– A multimeter with a function of measurement of the appropriate or megohometer

– Network transformer

– Indictance meter

– A Voltmeter (ideal digital)

For the most accurate measurements it is necessary to make sure that the room temperature in the room is between 20-22 degrees. To measure the resistance of the envelope, ohmeter is used. Therefore, it is necessary to measure the inductance of the envelope using a special counter. For a functional sensor this figure must be positioned somewhere between 200-400 mh.

Or the big difference of the inductance index compared to this value indicates a defective sensor.

• Check the signal with an oscilloscope: it is the most accurate method and, in fact, the most used by professionals. To perform this check, an oscilloscope and a special program are needed. This method does not require the removal of the sensor, since it is possible to observe the formation of the signal, also from the position. The digital oscilloscope will allow you to easily detect irregularities in the functioning of the injection system. If there is a signal from the sensor and its output parameters do not correspond to the normal, the car can be torn, the engine does not work stable. This indicates that there are defects of the sensor itself or disk disk. The real state of affairs will be evident after studying the oscillogram of the synchronization of the voltage measured at the exit of the sensor.

We presented three methods to check the engine tree sensor. In general, the choice of the method depends on the skills and skills available. The principle of controlling the engine tree sensor is the same for all motor vehicles models.

5. Tips to prevent the curved sensor of the defective sensor

To avoid the defect of the engine tree sensor, most specialists recommend paying particular attention to the following details:

• Avoid penetrating dirty and dust in the space between the sensor and the synchronization disc
• Avoid replacing the defective sensor with a new one if you do not have the necessary knowledge, because it is possible to violate the distance between the synchronization disc and the sensor nucleus. Usually the correct value is in the interval: from 0.5 to 1.5mm. Any other value will lead to the deterioration of the sensor barely replaced.
• Check the engine temperature increases because they can increase the geometric size of the coil, as well as the breakdown of the winding wires. When the sensor cools, the dimensions decrease and contacts are restored on condition that they are not broken. Most of the time when the Sensor of the Motor Motor School The car is blocked, it does not start. If there are no injuries inside the sensor, with cooling it will return to the initial shape and the car will begin.
• Avoid the corrosion of the wiring wires.
• In some cars, the motor tree sensors, as well as those of the camshaft are completely identical. Therefore, if you suspect a defect of one of them, it is better to change them and restart the car.
• When you buy a sensor of the engine tree it is good to bring the old one with you. At the same time, you can bring with you a multimeter, to avoid buying some false, that is, catchets without electronic filling.
• Taking a long journey it is advisable to wear such a free sense of in the car. Without the other sensors, the car will begin, but not without it.

So, if your car also presents one of the aforementioned symptoms and suspected that it could be a defect in the engine, we are waiting for you Our service in Brasov!
