P0173 and P0170
I know that some of you will get mad at me because we have thread about those code and i did search already and i got an idea but i really would like to share my problem and see if you guys would be able to help me out. So my car is 2006 c230 and it has 71k on it. I did a post couple days ago about cel with the code P0022 which is the intake camp sensor. I went to the shop on Thursday and they replaced it for me then later on the same day i went to get a change oil and they used the rcommended oil and oil filter and we took a look at the air filter which was really dirty, i could not believe it so anyways the guy order 2 air filter and replaced it. So that night i drove the car for about 100 mile and i drove it to work on friday with no problems. On satarday morning i'm about to leave to work and the cel came back on. I went to work and the car drive fine so late that night i was leaving from work and when i start the car it start fine but the muffler tip were shaking for like 15 seconds and it went back to normal and the car drive fine. This morning i took it to kragen, auto zone and to car quest to get the code and 3 of them told me that they don't do that anymore so i drove it to the shop and the car gave 3 codes, P0022 which was replaced on thursday already then it gave P0173 fuel trim and P0170 fuel trim code. So do you guys have any idea?

After this - if you have no success - because the fuel trim is out on both banks you will have to check the MAF.
Good luck

You lost the clip? Are you sure it's not lying on the bottom plate?
I can't advise you where to buy spares. Been out of the US too long.

I didn't get mine replaced under warranty. I got the CEL P0022 once. I pulled the connector, cleaned the contacts with denatured alcohol, and reset the CEL. ~5K miles now and still no CEL. Those sensors are too damn expensive to just replace on a CEL.

Why do the dealer and shops keep throwing out the BS, that the cam sensors need adjustment when replaced? I have the STAR WIS service manual, and it says nothing about adjustment when replacing. The holes for the sensor aren't slotted or anything, so if there is an adjustment, it must be through STAR.
There is no adaption required for these sensors that I know of. The ECU just pics up the input & settles down to it after a few minutes of running. What people do forget to d
