2.7.8. Check of pressure of oil and sensor of pressure of oil

GENERAL INFORMATION

The manometer used for check of pressure of engine oil and operability of the sensor of pressure of oil

And – the oil pressure sensor,

3 – wire of grounding of the manometer


If during the operation of the engine the control lamp of pressure of oil lights up and the sound signal is distributed, it can be caused by the following reasons:

 – level of oil is lower than norm;
 – existence of malfunction in an electric chain of the sensor of pressure and control lamp;
 – unsatisfactory operation of the oil pump;
 – too big gap in bearings of a bent shaft.

At fire of a control bulb of pressure of oil on the working engine immediately switch off the engine. Using the probe for measurement of level of engine oil, check the level of oil and if necessary, bring it to norm. Start the engine on turns of idling and check that the control lamp of pressure of oil does not burn any more. In this case it is possible to continue the movement.

If the level of engine oil is normal, and the control bulb of pressure of oil burns, do not continue the movement independently, and tow off the car in a workshop for check of pressure of oil.

If pressure of oil is normal, check the sensor of pressure of oil and электричес I forge a sensor chain.

For check of pressure of oil and the sensor of pressure of oil it is necessary to use the special manometer in which it is possible to screw in the oil pressure sensor.

Check
PERFORMANCE ORDER
1. Check the level of engine oil and, if necessary, bring it to norm.
2. Warm up the engine up to the normal working temperature.
3. Unscrew the sensor of pressure of oil from the holder of an oil filter and screw in it in the manometer, see rice. The manometer used for check of pressure of engine oil and operability of the sensor of pressure of oil.
4. Screw in a manometer adapter instead of the oil pressure sensor in the holder of an oil filter.
5. Connect a wire of grounding of the manometer to the mass of the car.
6. Using additional wires, connect a control light-emitting diode with the positive plug of the accumulator and contact of the sensor of pressure of oil. The light-emitting diode has to burn.
7. Start the engine and smoothly increase engine turns. With an excessive pressure in petrol engines of 1,2-1,6 bars and 0,75–1,05 bars for diesel engines, the light-emitting diode has to go out. Otherwise the sensor of pressure of oil is faulty.
8. Increase engine turns to 2 000 rpm. At a temperature of oil of +80 °C the excessive pressure of oil has to be not less than 2,0 bars. Smaller pressure of oil indicates wear of bearings of a bent shaft.
9. Continue further increase in turns of the engine. At the same time pressure of oil should not exceed 7,0 bars. Otherwise the valve failed perepuskny and it is necessary to replace a cover of the oil pump with the perepuskny valve.
10. Install into place the oil pressure sensor with a new sealing ring and tighten its moment 25 Nanometers.
