My car just threw P0341 and P0342 error codes so I need to replace one of the Cam sensors on the passenger side. What is the correct part number for this sensor?
Thanks. Yes after doing some research I will go ahead and change all 4. I just want to know the location of the one that triggered the fault code.
Go ahead inspect Bank-1 exhaust CPS for oil
It's the one closest to the battery side.
Once oil is found in the harness the repair is no longer just a new sensor that may still read same error.
Ppl report the latest new CPS part number lasting less than a year. It may be fixed temporarily.
The real fix is to remove extreme engine heat with better cooling oil.

I checked the 2 sensors closest to the battery and saw that one had a little bit of gunk on it. Noticed a slight gloss on the connectors of both sensors indicating some oil seepage. I also unplugged and inspected the ECU and thankfully it was dry as a bone. Just purchased 4 OEM MB sensors with the green o-rings from a local parts distributor. Hopefully this will clear the CEL as I noticed they come up as permanent codes and wouldn't go away when I tried to clear them last night. Do you know how long/how many miles it will take to learn/recognize a fix for permanent codes?

I don't know how long... probably right away or couple driving cycles. Your days without a scanner are numbered....use that to reset faults.
Fixing it well is the most important thing to do ...
Use pigtails to preserve your previous oil-free harness.
