why is my oil temp gauge always reading warm on

• 2024-01-26

There are 10 reasons why the oil gauge light remains on:

1. The temperature of the car engine is too high: When the vehicle's engine is at high temperature, it is very easy for the oil to become thinner. After the thinner oil is lost in a large amount from the fitting gap, the oil pressure drops, causing the engine oil lamp to alarm.
Solution: Cool the engine and add engine coolant.

2. The oil level sensor is faulty. The judgment method is to clamp the multimeter probe onto the two wiring terminals of the variable resistor of the fuel sensor. If the result shows that it does not meet the standard, it means that the sensor has malfunctioned.
Solution: Replace the oil level sensor.

3. The instrument coil is short circuited. A short circuit in the instrument coil can also cause problems with the oil gauge.
Solution: It is necessary to go to the repair shop for maintenance in a timely manner.

4. Excessive oil viscosity causes the oil gauge light to remain on.
Solution: Replace with a new engine oil.

5. The pressure limiting valve is blocked or improperly adjusted, causing oil leakage at the sealing connection in the oil circuit.
Solution: Go to the repair shop to adjust the pressure limiting valve.

6. The circuit problem of the indicator light itself. The circuit is open or short circuited, making it impossible to read the oil level sensor information.

Solution: You need to go to the 4S store to troubleshoot the wiring, find the faulty wiring, and then replace the wiring to solve the problem.

7. Insufficient or excessive oil level.
Solution: If there is too much oil, reducing the oil level in the tank to a normal level can solve the problem; If there is a shortage of oil, it is necessary to add oil.

8. The oil filter and suction plate are blocked. Long periods of non cleaning can easily cause impurities to block the oil filter and suction plate, leading to a decrease in oil pressure.
Solution: Clean the engine oil filter and suction tray.

9. If the return valve of the main oil duct is damaged or malfunctioning, and the spring of the return valve is fatigued, softened or improperly adjusted, the mating surface between the valve seat and the steel ball is worn or jammed by dirt, resulting in a loose closure, the return oil volume will significantly increase, followed by an oil lamp alarm.
Solution: Replace the return valve.

10. The elasticity of the fuel gauge in the car's fuel tank has disappeared, causing the fuel gauge light to remain on.
Solution: Go to the 4S store to replace the oil gauge with a new one.

The reason why the instrument panel thermometer light is on is:

1. There is a malfunction in the engine's cooling system;
2. Engine lacks oil and water;
3. The antifreeze level is too low;
4. Engine leakage;
5. AC relay and fan relay malfunction;
6. The fuse has blown.

The solution for the instrument panel thermometer light to turn on is:

1. Open the engine hood and check the engine's working condition;
2. Check the water level and check if the engine is leaking liquid;
3. Check for lack of antifreeze;
4. Check if there are any faults in the engine's cooling system;
5. Check for issues with the AC relay, fan relay, and fuse.
