Mercedes-Benz GLA35 AMG Oil Pressure Sensor Replacement Costs

What is the Oil Pressure Sensor all about?

Oil is vital for your engine – you need enough oil to lubricate and reduce friction throughout the engine. There’s no way to visually determine how much oil is being pumped through your engine, so your car’s computer relies on the oil pressure sensor to determine the flow.The oil pressure sensor is a basic electrical switch that provides information to the instrument cluster’s oil pressure gauge with the accurate real-time pressure. When the pressure is too low, not enough oil is being pumped through the engine to lubricate and cool components. When pressure drops below a threshold set by the automaker, the engine oil light on the car’s dashboard illuminates, warning you that driving could be dangerous.

Keep in mind:

There is no way to visually determine the operating condition of your oil pressure sensor.
If the sensor fails, it is impossible to determine whether there is sufficient oil flow/pressure to lubricate and protect your engine.
If your oil pressure sensor fails, it should be replaced immediately.

How it's done:

The vehicle is raised and supported on jack stands and tire is removed
The defective oil pressure sensor is removed
The new oil pressure sensor is installed
The engine is started and oil pressure is checked then the vehicle is taken off the jack stands
The vehicle is road tested for proper operation

Our recommendation:

Your car’s oil pressure sensor is an electrical component, and can be subjected to a number of issues, including wiring damage. If you suspect damage to the sensor, or have noticed your oil light come on, have it inspected and diagnosed by one of our expert mechanics.

What common symptoms indicate you may need to replace the Oil Pressure Sensor?

Oil pressure light is on
Oil pressure light turns on and off (can indicate several potential problems)
Depending on your make and model, you may have an oil pressure gauge that displays pressure in PSI. Note any drops below normal operating pressure.

How important is this service?

It is absolutely vital that your engine oil pressure be constantly monitored for potentially dangerous conditions. If your oil pressure sensor isn’t working properly, it cannot do its job, and must be replaced. If your oil pressure light comes on, call one of our expert mechanics immediately (driving with the light on can potentially cause damage).
