faulty oil pressure sensor
The causes of oil sensor failure are:
1. The engine oil storage is too small.
2. The oil is dirty or sticky.
3. The oil is lean or the engine temperature is too high.
4. Oil leakage from the oil pipe.
5. The opening pressure of the bypass valve is set too high or too low.
6. Oil sensor plug, pressure gauge or circuit failure.
7. The pressure limiting valve or pressure relief valve spring is too soft, the hairpin or the steel ball is damaged.
The solution to the oil sensor failure is:
1. The engine oil storage is too small, resulting in no oil or less oil in the lubrication system, resulting in low oil pressure. Solution: add fuel.
2. Dirty or viscous oil makes the oil pump unable to effectively inhale and pump out the oil, resulting in low or no oil pressure. Solution: Change the oil.
3. The oil is thin or the oil becomes thin due to high engine temperature, which will leak from the gaps of the friction pairs of the engine, resulting in low oil pressure. Solution: Change the oil or overhaul the cooling system.
4. Oil leakage from the oil pipe, damage to the oil pump or excessive wear of its components will lead to reduced oil intake and pump output, or no amount at all, resulting in low or no oil pressure. Solution: Repair.
5. The clearance between the crankshaft and the large and small tiles exceeds the standard, resulting in oil leakage, resulting in low oil pressure. Solution: Repair.
6. The pressure limiting valve or pressure relief valve spring is too soft or the hairpin or steel ball is damaged, causing the valve function to disappear or weaken, resulting in a decrease in oil pressure. Solution: Replace and repair.
7. The oil pressure is low due to the failure of the oil sensing plug, pressure gauge or circuit. Solution: Replace the check.
The oil pressure must work within a reasonable pressure value range. If the oil pressure is too low, due to the poor fluidity of the engine, each friction surface of the parts will accelerate the wear between the parts due to insufficient lubrication. Some car owners feel that the lubrication of the engine tears is not good due to low pressure. Is that because the higher the oil pressure, the better? No, if the oil pressure is too high, the oil seal and the oil pipe will be damaged, which will consume the engine power and will burn oil.
