Oil pressure sensor Mitsubishi Lancer 9
Content
The oil pressure sensor is designed to monitor the oil level in the engine. In the event that the oil level in the engine drops to a critical level, the sensor is triggered, as a result of which a red indicator in the form of an oiler lights up on the dashboard. It tells the driver what to check and, if necessary, add oil.
Where is the oil sensor installed on Lancer 9
To diagnose or replace the Mitsubishi Lancer 9 oil pressure sensor, you will need to disassemble it. It is located under the intake manifold, next to the oil filter, that is, on the right side of the engine. The sensor comes with wiring.
To remove it, you need a 27 ratchet head. Getting to the sensor is not easy. However, if you use a socket, extension and ratchet, you can easily unscrew the sensor.
Removal and installation of the oil pressure sensor
So, as I wrote above, you need a 27mm head with a ratchet. Access to the sensor is best opened on the left side in the direction of travel. However, you will need to remove the air filter housing. After removing the case, you will see the sensor on the terminal suitable for it.
It is advisable to unscrew the sensor with a long head, for those who do not have one, simply bend the contact on the sensor and unscrew it with a short head. The process is quite simple: they removed the plug from the sensor, bent the contact and unscrewed the sensor with the heads. The photo below shows the process.
Diagnostics DDM Lancer 9
After removing the sensor, you need to make sure that the problem is really with it. This will require a multimeter.
We put the multimeter in the test position and check if there is a contact on the sensor. If there is no contact, then the reason is in it.
Using a compressor or pump, we check the pressure of the sensor. We connect the pump with a monometer, create pressure on the sensor and look at the indicators. The minimum pressure in the system must be at least 0,8 kg / cm2, and as the pump operates, it must increase. If this does not happen, the sensor is defective.
Article and price of oil pressure sensor Lancer 9
After we have verified that the sensor is defective, it should be replaced. Original sensor Mitsubishi 1258A002. Its price is about 800-900 rubles. However, in addition to the original, you can find many analogues of very different quality.
Sensor analogues
- AMD AMDSEN32 from 90 rubles
- BERU SPR 009 270 руб
- Bosch 0 986 345 001 from 250 rubles
- Futaba S2014 from 250 rubles
These are far from all analogues presented on the domestic market. When buying a sensor, we recommend that you buy it only in trusted places. It is not worth buying too cheap, as there is a chance that it will quickly fail.
After installing a new sensor, the problem with the indicator light on the instrument panel should go away. If the light is still on, there may be something else.
