2005 Mercedes c230 Camshaft Position Sensor Repair in Tualatin, Oregon

How do you figure out that I have a problem with my camshaft position sensor?

A technician or a mechanic will use a scan tool in the area where they think your camshaft and your crankshaft are located. They take the information that they find from this and compare that to where those things are actually located. Your position sensor will then be tested as well. If the readings are wrong then your c230’s position sensor will be replaced.

Ok, well, since this is my first time ever hearing of anything like this… What is a camshaft position sensor?

The camshaft position sensor functions on electricity and it is positioned next to your engine’s camshaft. The sensor monitors the camshaft as it rotates and it reports that information to the ECM. The computer then uses this information to control the timing of fuel injection.

What is an ECM?

ECM stands for the engine control module. It is your vehicle’s computer.

Wait, if you replace the sensor then don’t you have to recalibrate or something? I mean, it is a sensor.

Yes. You are correct. You have to recalibrate the sensor in order for it to work correctly.

If I brought this into a place with an OBD code checker then what codes would I see if I do have a camshaft position sensor problem?

You would likely see one of the following codes appear if you are having a problem with your c230 and the problem is your camshaft position sensor:

  • P0340: Camshaft Position Sensor “A” Circuit
  • P0345: Camshaft Position Sensor “A” Circuit
  • P0343: Camshaft Position Sensor “A” Circuit High

If I don’t go the OBD code method then what are some of the physical symptoms that I would experience if this really is a problem.

You will likely see your check engine light illuminate. Your c230 will start performing poorly and will have very bad returns on miles per gallon. If you ignore that warning then your engine may begin stalling or begin to fail to start completely.

Alright, I get this thing is important but, exactly how does this thing do its jobs?

The sensor will read the position of the camshaft as it a. It reports that information to the ECU. The ECU takes that information and compares it with the data it receives from the crankshaft position sensor. If the two readings are different then the computer assumes that there is a problem with the timing. It will adjust its own settings to make sure that the engine does not get damaged.

Well, I’d like to get this checked out. Can I drive it in?

Honestly, most of the vehicles that have a verifiable camshaft problem cannot be driven. However, if you find that you can drive it for some reason, then you should avoid it. It is dangerous.
