Reasons Behind Oil Pressure Switch Failure in Your Mercedes From The Best Repair Shop in Dallas

Posted on | 6 Dec 2019 By Anita Gaal

The oil in your Mercedes is under continuous pressure. This pressure keeps it flowing through your vehicle. The oil is needed to keep all of the critical components in the engine lubricated. If there isn’t enough pressure, the oil will not be distributed correctly. This will lead to friction and component failure. The oil pressure switch, along with other components, detects the pressure level. If there is an issue, it is able to alert the driver. It will do so by activating the dashboard warning light.

The Function of the Oil Pressure Switch

The oil pressure switch is a critical component that can warn you if you are experiencing failure. You may only see the issue as an annoyance, but having properly-maintained oil pressure is crucial for your engine to run properly. If there isn’t enough oil to lubricate the metal surfaces, your car will produce heat and experience friction.

Knowing there is a problem before it is too late is key to preventing additional damage to engine components. If the dashboard warning light is triggered, you will have enough time to get off of the road and assess the problem.

If the pressure switch malfunctions, you will not be warned if there is an issue detected. Not knowing there is a problem can lead to further damage and complete engine failure.

Signs of a Failing Oil Pressure Sensor

Like any other component in your Mercedes, the oil pressure switch can fail. The symptoms of a failing sensor include:

Oil Pressure Light is Illuminated

When the oil pressure sensor begins to go bad, it can give erratic readings. These inaccurate readings will trigger your dashboard light. If the light comes on, check your oil level. If it is at the correct level and the engine sounds normal there is a good chance that the sensor is bad. If the oil level is fine, but there is a ticking or grinding noise, you oil pump may have failed. Do not run your vehicle with a failed pump. When the oil level is low, you may be experiencing an oil leak, a lack of pressure, or you may be burning oil. Do not drive your vehicle under these circumstances.

Oil Pressure Light is Blinking

Oil pressure problems are usually not intermittent. If the oil pressure light is blinking irregularly, this is a sign that the pressure switch sensor is failing.

Oil Pressure Gauge Readings

If your oil pressure gauge readings change from very high to very low, this can be an indication of a bad sensor. Don’t just add oil without checking the level. Using too much oil can be just as bad as not having enough.

Check Engine Light is Illuminated

False oil level readings can trigger your check engine light. Your check engine light can be activated by a number of factors. This light is there to let you know when your car detects a problem. Always take your Mercedes to a certified mechanic to have a diagnostic check performed.

Preventing Oil Pressure Switch Problems

Oil pressure switches can fail over time. The best ways to prevent issues is with regular maintenance. Keeping current on oil and filter changes is crucial for your engine to run properly.

Other ways to ensure that your vehicle is kept in excellent condition is to:

• Only have a certified mechanic work on your Mercedes-Benz
• Have frequent inspections performed
• Keep current on your regular maintenance schedule
• Don’t put off having any issues diagnosed and fixed by a certified mechanic
