How much does the crankshaft sensor cost on average for a VAZ 2107, 2109, 2114?

Why do you need DPKV?

The crankshaft position sensor is necessary to determine the location of the pistons, namely when they are at TDC. This is necessary to supply a spark to the combustion chamber and ignite the fuel-air mixture.

The sensor operates on the Hall effect. The DPKV is connected to the crankshaft pulley, which has a crown with one missing tooth and helps determine the TDC sensor.

There is a magnet inside the sensor, which is a sensitive element and helps to read readings from the pulley. As soon as the magnetic connection between the sensor and the pulley is lost and the ECU receives a signal that it is necessary to apply a spark to the cylinder, which is now at TDC.

Description and purpose of the part

The crankshaft sensor (CPS) is an element of the electronic engine control system. Serves to control the ignition timing in the engine cylinders, determine the injection timing, and control the valve timing system. Consists of a steel core with copper winding. It is filled with compound resin and placed in a housing made of plastic. The sensor has a 50-70 cm wire with a connector that is connected to the motor control unit. Also called timing sensor.

The following indicates that it is time to change the crankshaft sensor on the VAZ 2107, 2109, 2114:

• The car won't start.
• Power has dropped.
• The engine runs rough and runs intermittently.
• The car stalls when starting to move.

Reasons for failure

Sensor failures can be attributed to several reasons due to which the sensor most often fails.

• Time factor;
• Mechanical damage;
• Damage to the power circuit;
• Magnet contamination;
• Pulley damage;

Now more about each reason.

• Time factor. The main reason for the failure of the DPKV is its aging; the sensor is located very low, which quite often exposes it to humidity, dust and dirt. Such impacts damage the sensor connector and its magnet.

• Mechanical damage. As mentioned above, the sensor is located very low, which exposes it not only to contamination, but also to damage. When driving on country roads, stones or the like may enter the sensor. items. The sensor can also fail due to damage to the crankshaft pulley.

• Damage to the power supply. A special shielded wire is used to power the sensor, which helps remove interference generated during engine operation. Quite often, the sensor’s power cable becomes frayed or its insulation dries out over time, which leads to interference in the power circuit or even to its breakage.

• Magnet contamination. A magnet tends to attract any metal shavings, and when working with rubbing parts, these shavings are inevitable. Quite often, a large amount of metal shavings adheres to the sensitive part of the sensor, which dulls the sensitivity of the sensor.

• Pulley failure. The pulley is involved in the operation of the sensor and its curvature or separation from the damper can lead to improper operation of the sensor.

Types of spare parts

There are three types of DPKV:

• Induction or magnetic . The device contains a coil with a magnetized core. It is characterized by simplicity of design. The operation of the sensor is based on the effect of electromagnetic induction. No additional power required.
• Hall sensors . They work on a microcircuit. It is located in a housing with a magnetic core. Characterized by high signal output accuracy. But the sensor needs constant voltage.
• Optical . Consist of a light source with a receiver. The operation of such devices is based on the photoelectric effect.

According to the condition you can purchase the sensor:

• New.
• Used.

Depending on the VAZ brand, you can buy a crankshaft sensor for:

• Frets 2107.
• Frets 2109.
• Frets 2114.

Depending on the country of manufacture, you can install an imported or domestic crankshaft position sensor. Depending on the manufacturer, you can buy an original or non-original sensor for a VAZ.

At VAZ you can get DPKV from the following company:

• SOATE.
• AvtoVAZ.
• ZOMMER.
• BAUTLER.
• Omega Group.

Pulley failure

The pulley affects the operation of the sensor and, therefore, the operation of the entire engine as a whole. Its curvature can lead to incorrect readings and, as a result, improper operation of the engine.

There are two types of pulleys: cast and with damper. A cast pulley is more reliable and durable, but the second type of pulley with a damper rubber insert is often damaged.

One of the most common failures of this pulley is the rotation of the crown relative to the crankshaft. Such a breakdown leads to displacement of the crown and incorrect determination of TDC by the sensor.

Factors affecting the cost of spare parts

Crankshaft sensors for VAZ 2107, 2109, 2114 are sold at different prices. The cost is determined by the following factors:

1. Part condition.
2. Type of spare part by design and operating principle.
3. Originality.
4. Car model.
5. Reputation of the manufacturer.
6. Spare part quality.
7. Place of purchase.
8. Delivery required.
9. Implementer's pricing policy.

Examination

The check must be carried out both externally and using diagnostic devices. Sometimes just a visual inspection is enough to determine the problem, so let's start there.

Sensor check

This is done by checking the sensing element for contamination. If the sensor magnet has a lot of chips on it, this indicates that it is not working properly. The sensor must be cleaned and reinstalled.

Next, the connector and power circuit are checked and there should be no traces of carbon deposits, rust or other types of damage.

Pulley check

The pulley must be inspected for its integrity and evenness.

Instrument testing

Such a check can only be carried out using special diagnostic equipment. Diagnosing DPKV in this way will be effective only when the check light on the car’s dashboard is on.

Crankshaft position sensor VAZ 2114

The diagnostics showed that the VAZ 2114 crankshaft position sensor has failed? The VAZ 2114 crankshaft position sensor comes in 3 types: induction (electromagnetic), Hall and LED. The most commonly used are induction. The induction sensor consists of a coil with a magnetic core inside in a nylon housing. The coil is sealed with a special resin inside the housing.

The crankshaft position sensor of the VAZ 2114 has a cylindrical shape; the housing is provided for mounting in a seat. The sensor also has a cable for connecting to the machine’s electrical circuit and a plug with three pins. In Hall sensors and LED sensors, the working elements are, respectively, a semiconductor and an LED.

The cost of the sensor depends on whether it is new or used, the manufacturer, as well as on availability in our warehouse or delivery time to our store.

The VAZ 2114 crankshaft position sensor is the only indicator that, if it malfunctions, the engine will stop starting. The crankshaft position sensor transmits signals about the position of the crankshaft and its speed to the computer. This allows you to determine the moment when a spark discharge needs to be applied to the spark plugs. It also allows you to adjust the composition of the combustible mixture, the moment of injection of the mixture into the combustion chambers, etc. It is installed next to the crankshaft pulley, on the crankshaft gear cover or the oil pump. It cannot be repaired, it can only be replaced. It is selected for a specific car model by VIN number. It is advisable to purchase exactly the same crankshaft position sensor as was installed.

Sensor manufacturers:

HELLA, BEHR, VDO, BOSCH, NGK.

When to buy a crankshaft position sensor:

— The CHEK ENGINE light on the instrument panel lights up; — Unstable engine operation at idle, floating speed; — Increased fuel consumption; — Engine power has dropped or the engine cannot start at all; — With all the above symptoms, a breakdown of the crankshaft position sensor was diagnosed at the service station.

Replacement

Replacing the sensor is a fairly simple job that even the most distant person from cars can handle. The job involves unscrewing one screw and removing the connector from the sensor.

It is best to carry out work from the inspection hole, but if there is none, then replacement can be done by removing the front right wheel.

Let's start replacing

• Remove the connector from the sensor

• Unscrew the fastening bolt using a 10mm wrench

• We take out the sensor. This may be difficult to do, but since we no longer need the old sensor, we can take it with pliers and turn it in the mount.

• Install the new sensor in reverse order.
