REASON
|
ELIMINATION METHOD
|
|
At inclusion of ignition the control lamp of pressure of oil does not light up
|
| The sensor of pressure of oil is faulty | At the included ignition disconnect the electric socket from the sensor of pressure of oil and connect it to mass of the car. If the control lamp of pressure of oil thus lights up, means, the sensor of pressure of oil is faulty and it is necessary to replace it |
| Break in an electric chain of the sensor of pressure of oil or the oxidized contacts | Check an electric chain of the sensor of pressure of oil and a condition of contacts |
| Malfunction of a control lamp of pressure of oil | Replace a control lamp of pressure of oil |
|
After engine start the control lamp of pressure of oil does not die away
|
| Too high temperature of engine oil | At increase in turns of the engine the control lamp of pressure of oil should go out |
|
The control lamp of pressure of oil does not die away at increase in turns of the engine or lights up in the course of operation of the engine
|
| Too low pressure of oil | Check level of engine oil and, if necessary, finish it to norm. Check pressure of oil |
| Short circuit on mass of a wire from the sensor of pressure of oil | Disconnect from the sensor of pressure of oil the electric socket and isolate it. Include ignition. If thus the control lamp of pressure of oil lights up, check a condition of an electric chain of the sensor of pressure of oil |
| The sensor of pressure of oil is faulty | Replace the sensor of pressure of oil |
|
Low pressure of oil on all turns of the engine
|
| Level of engine oil in the engine is lower than norm | Finish level of engine oil in the engine to norm |
| The mesh filter is polluted or there is an opening in a tube of a maslopriyemnik | Remove the oil pallet and clear the mesh filter or replace a pipe of a maslopriyemnik |
| The increased gap in bearings of a cranked shaft | Check a condition of bearings of a cranked shaft and, if necessary, replace them |
| The oil pump is faulty | Remove the oil pump, check its condition and, if necessary, replace |
|
The reduced pressure of oil on low turns of the engine
|
| Perepuskna the valve of the oil pump is in constantly open situation | Remove perepuskny the valve and check its condition |
|
The increased pressure of oil at turns of the engine more than 2 000 rpm
|
| The valve does not open perepuskny | Remove perepuskny the valve and check its condition |
