From what the oil pressure sensor shows, you can understand how correctly the car works. Failures in the pressure sensor readings indicate that there are malfunctions in the car. However, such malfunctions can have several problems.
Necessary
- - control pressure gauge;
- - sensor for measuring oil pressure;
- - oil filter;
- - mineral oil;
- - crankshaft valves.
Instructions
Step 1
Start the car and drive some distance at a speed of 40 km / h. With a reduced oil pressure on the instrument panel, a special sensor will light up, which determines the rate of indicators.
Step 2
Improper operation of the oil pressure measurement sensor can lead to the fact that you will see incorrect data on the engine lubrication system. So try replacing the pressure sensor first. After replacement, measure if its performance meets the standards stated in the vehicle specifications.
Step 3
The reason for the drop in oil pressure may be a clogged pressure relief valve. In this case, it must be cleaned. Unscrew it, being careful not to damage it, and rinse thoroughly. After installing the valve, adjust with a test pressure gauge.
Step 4
Check for a leak under the stuffing box. This is a sign that the crankshaft journals are worn out and need to be replaced. If there is no leak, but the pressure indicator sensor shows a deviation, the reason lies in the wear or malfunction of the camshaft valves. Try to adjust them. Otherwise, the valves must be replaced.
Step 5
A worn filter may be the cause of low oil pressure. Replace the oil filter. Then check the quality of the oil used. Better to use mineral. Their thicker consistency will raise the pressure level to the required level.
