The crankshaft position sensor in your Mercedes-Benz is also known as the engine speed sensor. This sensor is part of your vehicle’s fuel injection and ignition system. Its job is to measure the engine’s RPM as well as the engine’s crankshaft position. If this part fails, your car will not start, leaving you stranded.

Crankshaft Position Sensor Failure Warning Signs

It is common for a crankshaft position sensor to have issues in a Mercedes-Benz. There are sometimes warning signs that you may see before complete failure occurs. If you come across any of the following issues, give us a call and we can perform an inspection and replace your sensor if needed.

Intermittent Starting

It might become difficult to start your car. Sometimes you may have to try several times to get your car to start, while at other times it might start right away. This will happen more often when the engine is still hot.

Stalls or Misfires While Running

If your car dies while you are driving down the road, this can be a sign that your crankshaft position sensor is going bad. This can be dangerous and lead to an accident in some situations. Your car may also backfire and idle roughly. Have your vehicle checked out immediately if you notice these symptoms.

Poor Acceleration

When you give your vehicle gas, it shouldn’t hesitate to move. If it does, and your car is accelerating slowly or has difficulty maintaining its speed, this can be very dangerous. When you don’t have proper acceleration, you may not be able to move out of the way of other vehicles quick enough. If you come to an emergency situation where you need to accelerate quickly to get out of the way of danger, you will not be able to do so. If the sensor is failing, it isn’t sending accurate information to the computer. This improper information will not allow the engine’s pistons to accurately synchronize, slowing down your vehicle’s response time.

Bad Fuel Efficiency

Your crankshaft position sensor might be the issue if you are experiencing poor fuel efficiency. If your car seems to be running alright otherwise, and you have had all of your scheduled maintenance performed, your sensor may be the offender.

Check Engine Light is On

You know that you have some sort of problem if your check engine light is illuminated. If you are experiencing any of the above issues along with the light you could have a bad sensor. Let your mechanic know about any of the issues that you have been having. They will be able to run a diagnostic tool to find your problem.
