The causes of oil sensor malfunction are: 1. Insufficient engine oil level; 2. Dirty or viscous engine oil; 3. Overly thin oil or excessively high engine temperature; 4. Oil pipe leakage; 5. Incorrect opening pressure setting of the bypass valve (either too high or too low); 6. Faulty oil pressure sensor, pressure gauge, or electrical circuit; 7. Weak spring, sticking, or ball damage in the pressure relief valve or pressure limiting valve. Solutions for oil sensor malfunction include: 1. Topping up engine oil; 2. Replacing with higher-quality oil; 3. Inspecting and repairing the cooling system and oil pipes; 4. Replacing the pressure limiting valve. The oil sensor is a device that monitors the oil pressure in a vehicle's engine, and the data it collects aids in maintaining proper engine operation.

What to Do When the Mercedes-Benz E260 Displays 'Add Coolant'?

Mercedes-Benz E260 displays 'Add Coolant' solution as follows: False Alarm: This is usually an issue with the liquid level sensor and its related wiring. To determine if it's a false alarm, you can only manually open the coolant cap and observe whether the actual liquid level is normal. Engine Cooling: Park the car on level ground and wait for the engine to cool down. Ignition: Put the car into ignition mode. Check Water Temperature: The cooling system is pressurized, so you can only open the radiator cap after the engine has completely cooled down. The coolant temperature gauge must display below 70 degrees Celsius, otherwise, you might get scalded by the high-temperature coolant that could spill out. Filler Cap Operation: Place a cloth over the antifreeze filler cap, turn the cap counterclockwise half a turn to release any remaining pressure. Observe Coolant: If the coolant is level with the indicator rod on the filler cap when cold or about 1.5 cm higher when hot, it indicates there is sufficient coolant in the radiator. Actual Coolant Consumption: Coolant is a mixture of various additives and distilled water. Water evaporates, so as the mileage increases, the coolant will indeed be consumed. After being prompted to 'Add Coolant,' fill it up and observe again. If the prompt reappears shortly after, it indicates that it's not normal consumption.
