What Causes the Maintenance Required Light to Come On?

Here are the most common causes of maintenance required light on your vehicle.

Malfunctioning Sensors

A malfunctioning sensor is one of the notable causes of a flickering oil light. Check the sensor to determine if it’s functioning as required. The sensor might be detecting oil issues on your vehicle because dirt and other particles made their way into the pump.

Low Oil Pressure

If you don’t solve the low-pressure level, your vehicle may be damaged beyond repair. You can correct the issue by replacing the oil with the correct oil viscosity.

Worn out Oil

Regular maintenance is vital to keep your car in the best performance and shape. It would be best if you had an oil change every three months or after 5,000 miles. Changing your oil often ensures fresh oil is circulating on your engine.

Faulty Oil Pressure Gauge

You might have changed your oil and replaced the sensor, but the light does not turn off. The issue may be an oil pressure gauge, which malfunctions due to electrical problems. Ask the mechanic to perform an oil pressure test to determine if there is enough pressure.

Engine Wear

Oil circulates through the engine using camshaft bearings. The oil moves flawlessly if the parts are worn out, reducing oil pressure. An oil pump is designed to force oil through narrow areas. A faster engine leads to a higher flow rate.

A worn-out pump will not generate the required pressure because of internal leaks. Stop the engine and have a pump replacement.
