When Do Mercedes-Benz Oil Pressure Sensors Need to Be Replaced?

But what does it mean when your Mercedes-Benz's oil pressure light comes on and the oil dipstick indicator shows oil up to the max line? Now you're confused. What’s the story with that?

More than likely the oil pressure sensor is faulty and needs replacing. A faulty oil pressure sensor can give false oil pressure readings, which can trigger the dashboard warning light.

The oil pressure sensor is a small electrical conductor circuit with sensors, encased into a shell with a connector on the back. This is screwed into the block, usually at the top of an engine near the rear of the block, with a wired connection plugged into the back.

Oil passes and enters the oil pressure sensor through a small hole at the tip. It measures resistance based on the oil pressure.

The oil pressure sensor is a critical part of the engine. It identifies any changes to the quality and pressure of the oil in the engine and sends a warning to the Mercedes-Benz's computer. This then sends a signal to the oil pressure gauge in your instrument panel.

When the oil pressure sensor fails the oil pressure gauge can show no pressure and the oil pressure light can flash on and off or stay on.

If the oil pressure light illuminates, stop the car in a safe place and check your oil level. If your oil level is low or not registering on the dipstick, don’t drive the car. Have someone bring you some oil or have the Mercedes-Benz towed to a mechanic.

Make sure to check the wiring and connection along with the sensor. It may not be the sensor that is faulty but the failure of other components. It is extremely important to have the Mercedes-Benz oil pressure sensor replaced if it is faulty.

If you continue to ignore the warning light and the Mercedes-Benz develops an oil leak, it may run low on oil - a problem that can do irreversible damage to the engine. Avoiding a small oil pressure gauge replacement cost could result in a very expensive engine replacement.
