oil temp gauge keeps fluctuating

• 2022-11-10

Cause analysis and solutions of oil temp gauge keeps fluctuating:

1. The engine oil storage is too small, resulting in no oil or little oil in the lubrication system, resulting in low oil pressure. Solution: refuel.

2. Dirty or viscous oil causes that the oil pump cannot effectively suck in and pump out the oil, resulting in low or no oil pressure. Solution: change the oil.

3. If the engine oil is thin or becomes thin due to high engine temperature, it will leak from the friction pair clearance of the engine, resulting in low oil pressure. Solution: change the oil or overhaul the cooling system.

4. The oil pipe leaks oil, the oil pump is damaged or its parts are worn out beyond the standard, which will lead to the reduction of oil suction and pumping, or no oil at all, resulting in low or no oil pressure. Solution: maintenance.

5.The clearance between the crankshaft and the large and small bearing pads is out of specification, resulting in oil leakage and low oil pressure. Solution: Maintenance.

6. The pressure limiting valve or pressure relief valve spring is too soft or jammed or the steel ball is damaged, which causes the function of the valve to disappear or weaken, causing the oil pressure to decrease. Solution: replace and repair.

7.Low oil pressure due to oil sensing plug, pressure gauge or circuit fault. Solution: replace and check.Sensor, which is also a device that directly affects the inaccuracy of the oil gauge, reflects the obstruction of data transmission or the inaccuracy of transmission, resulting in the failure of the oil gauge pointer to reach the accurate reading position. This type of precision equipment can only be repaired by professional debugging equipment of the repair factory. It shows that the problem of oil surface display is the most widespread problem encountered by motorists, some of which are caused by the jamming of the pointer or impurities in the meter. The appearance of this type is due to the dust accumulated by the day and the month.

The most important thing is to analyze the fault causes of transformer oil temperature gauge after it fails, and only clear the faults. The causes and possible problems can better handle the failure and prevent it from happening again.
