1997 Mercedes CLK230K P0341 Fault: How to Diagnose and Fix the Camshaft Position Sensor Issue

Model: 1997 Mercedes CLK230K Fault Code: P0341 Posted: 2014-03-01 10:09

I recently purchased a 1997 Mercedes CLK230K that has been idle for three years with no usage. The vehicle is now displaying a persistent OBD-II fault code P0341, which indicates an issue with the camshaft position sensor. This code remains active even when the engine is off and the ignition is on (reading 111.975). The car has accumulated 250,000 kilometers of mileage. I am completely stuck and unsure how to properly diagnose or resolve this issue. I have tested the connector for the Hall effect sensor but need guidance on whether my readings are within acceptable ranges. Any technical advice or troubleshooting steps would be greatly appreciated.

The P0341 code typically points to a faulty camshaft position sensor. Once the underlying issue is repaired, the fault code should clear. For accurate diagnosis and repair, refer to official OBD-II resource: http://www.obd-codes.com/p0341

Thanks for the response. I've tested the sensor connector with the ignition on but engine off, and the connections unplugged. Here are my readings: - Pin 1 (negative): 0V, resistance = 17 ohms - Pin 2 (signal): 11.37V, no signal detected - Pin 3 (positive): 11.7V, resistance = 920 ohms There is continuity between pins 1 and 3, measuring approximately 1000 ohms. I also tested the connection between ECU and sensor using pins 1 and 2 — continuity was confirmed (indicating a good connection). I couldn't test pin 3 as it appears to connect to a fuel relay. Are these voltage and resistance values normal? Is this likely a sensor failure? What other steps should I take before replacing the sensor? I'm feeling overwhelmed and would appreciate clear, step-by-step guidance.

Based on the readings, it's highly probable that the camshaft position sensor is faulty. For reliability and compatibility, it's recommended to replace it with an OEM part from a Mercedes dealer rather than aftermarket alternatives.

Thanks for your advice. Is there anything special I need to do when replacing the sensor? Or is simply unplugging and plugging back in sufficient? I've read that resetting the ECU may be necessary after replacement — but I'm not sure how to perform this. Does disconnecting the battery for a few minutes work, or is there another method? The original sensor was made by Hella, which is slightly cheaper than OEM parts. However, they're out of reach due to high cost. So I've purchased a replacement from Trucktec — it's still in the box and not yet installed. Should I proceed with this unit, or should I wait for an official part?
