So i just bought used Volvo c30 1.6d 2008 (220000km). And after few days of driving i noticed that sometime car isnt accelerating like it should. Board computer doesnt show any error. I connect it to car diagnostic and i fond 2 errors, Fault 1 : P2002 : Particulate trap efficiency lower than limits on bank 1 and Fault 2 : P0341 : Issue with the Camshaft position sensor detected..
Can someone suggest what could be exact problem?

the cam position sensor is telling the ECU where the cams are in relation to the crank shaft. The P0341 code is the ECU saying the signal is not in "spec" this is a generic code so it could be the sensor, wiring or perhaps the cam position itself. start by clearing the code to see if it returns. Next is to inspect the wiring, and cleaning the connectors for the sensor. finally you'd need to measure the output signal from the sensor itself. What most DIY types would do is simply replace the sensor and hope for the best :-). As to your P2002 code, that's pointing to the particulate filter so you would need to service that or if you do a lot of local driving, do a driving cycle to really heat up the car to burn off any excess soot. Google for some tips on a driving cycle.

 

Thanks for reply.

I just noticed that on 3 and 4 gear (must check on other gears) it wont pass 3000rpm. I press pedal to the max.
