Crankshaft sensor Nissan Almera N16
Content
The operation of the Nissan Almera N16 power unit is directly affected by the crankshaft sensor. The failure of the DPKV seriously affects the operation of the engine.
In most cases, the engine refuses to start. This is due to the impossibility of generating control commands in the ECU without obtaining information about the position and speed of the crankshaft.
Purpose of the crankshaft sensor
DPKV Nissan Almera N16 is used to determine the position of the crankshaft and its speed. Synchronizes the operation of the electronic control unit of the power unit. The ECU learns about the top dead center of the pistons and the angular position of the crankshaft.
During operation, the sensor sends a signal consisting of pulses to the engine control unit. The appearance of violations in the transmission of information leads to a malfunction of the computer and is accompanied by an engine stop.
Location of the crankshaft sensor on the Nissan Almera N16
To see where the DPKV is located on the Almere H16, you need to look from under the car. In this case, it is important to take into account that the installation site of the sensor is closed by the crankcase protection, which must be removed. The location of the DPKV is shown in the following photographs.
Sensor cost
The Almera N16 uses the original Nissan sensor 8200439315. Its price is extremely high and amounts to 9000-14000 rubles. DPKV Renault 8201040861 is also installed from the factory on Almera N16 cars. The cost of the brand counter is in the range of 2500-7000 rubles.
Due to the high cost of original sensors, they are not widely used in car dealerships. This makes it difficult to buy them. For this reason, many car owners are inclined to purchase analogues. Among them are many valuable options at an affordable price. The best analogues of the original Almera N16 sensors are presented in the table below.

| Creator | Catalog number | Estimated price, rub |
|---|---|---|
| Command max | 240045 | 300-600 |
| Intermotor | 18880 | 600-1200 |
| Delphi | CC10801 | 700-1200 |
| Earnings per share | 1953199K | 1200-2500 |

Crankshaft sensor test methods
The failure of the crankshaft position sensor is always accompanied by an error in the memory of the on-board computer. Therefore, checking the DPKV should begin with reading the problems of the computer. Based on the received code, you can determine the nature of the problem.
A further check involves removing the crankshaft position sensor from the vehicle. It is important to determine the presence of mechanical damage. Therefore, the body is subject to a thorough visual inspection. If cracks and other defects are found, the sensor must be replaced with a new one.
If visual inspection shows nothing, it is recommended to check the resistance. To do this, you need a multimeter or ohmmeter. The measured value should not exceed 500-700 ohms.
If you have an oscilloscope, it is recommended to connect it and take graphs. It is easy to find gaps in them. Using an oscilloscope allows you to more accurately check the DPKV.
Required tools
The list of tools that will be required when replacing the crankshaft position sensor is presented in the table below.
Table - List of funds for replacing DPKV
| First name | Special addition |
|---|---|
| Knucklehead | «10» |
| Ratchet | with hanger |
| Key ring | «for 13», «for 15» |
| Rags | For cleaning work surfaces |
| Penetrating lubricant | Loosen the crankcase guard |
It is possible to replace the crankshaft position sensor through the top of the engine compartment. To do this, you will need to remove the air filter housing. The disadvantage of this method is the need for sufficient flexibility of the hands and the ability to work "by touch". Therefore, most car owners change the crankshaft sensor under the bottom of the Almera N16. In this case, you will need a viewing hole or overpass
Self-replacement of the sensor on the Nissan Almera N16
Replacing DPKV with Almera H16 occurs according to the following algorithm.
- Remove the crankcase protection of the power plant.
- Remove the sensor terminal block.
- We unscrew the bolt securing the DPKV to the power plant.
- Remove the sensor. At the same time, keep in mind that its removal may be difficult due to sticking of the sealing ring. In this case, it is advisable to crawl under the sensor with a thin screwdriver.
- Install a new crankshaft position sensor on the Almera N16.
- Reassemble everything in reverse order.
