Attention! This deletes data from the memory devices, for example, the security code of the radio. Read the chapter's recommendations «Battery - removal and installation».
2. Disconnect the power wire from the sensor and unscrew the oil pressure sensor. The oil pressure sensor is located on the left side of the oil filter or next to the oil filter.
3. Connect auxiliary wires to the oil pressure sensor and control light to the battery. The control lamp should light up when connected to the battery. Instead of a battery and a test light, you can connect an ohmmeter, which should show 0 ohms. If not, then the oil pressure sensor should be replaced (see illustration).
18.3 Connect the auxiliary wires to the oil pressure sensor and control light to the battery
4. Slide a hose with a pressure gauge and a hose for supplying pressure onto the thread of the sensor mount. The hose must fit tightly on the thread.
5. Slowly increase the pressure. At a pressure of 0.35 bar, the control lamp should go out. If an ohmmeter is connected, it should start showing infinite resistance. Otherwise, the sensor must be replaced.
6. Install the oil pressure sensor in place, replacing the old sealing ring with a new one, and tighten it with a force of 35 Im.
7. Connect wire terminal «masses» (-) to the negative pole of the battery.
8. Set the clock.
Only vehicles with 150 hp engine.
The oil pressure sensor should be checked if the oil pressure reading on the instrument panel does not correspond to normal values.
9. Check sensor 1. To do this, disconnect the plug from the sensor (see illustration).
18.9 Check sensor 1. To do this, disconnect the plug from the sensor
10. Connect an ohmmeter to the sensor.
11. Start the engine and leave it to idle. The ohmmeter should show a resistance of 155 ohms.
12. Increase the engine speed to 3000. The ohmmeter should show a resistance of 45 ohms.
13. Check oil pressure.
If the oil pressure is normal, and the resistance recorded by the ohmmeter has significant deviations from the nominal values, then the oil pressure sensor must be replaced.
