Removing right oxygen sensor
I have a 99 clk 320. How can I remove front right oxygen sensor (passenger side before catalyst)? Should I access it from bottom of the car? Can anyone point me to right direction?
Thanks Bobby |

P0173, P0170, and P0130
OK. Got it. One could access it from the top after removing air intake tube.
So I did replace the O2 (Bank 1 Sensor 1) but the car still has rough idle and shakes even more when I turn the AC on. I did scan for code and I am getting P0173, P0170, and P0130 (pending). The scanner does not clear the codes and it kept saying: Command sent 3 codes remain. Before changing the O2 I did: clean MAF (no go) Replaced the MAF insert (no go) Note: I bought the MAF insert from ebay which I think is generic one since it does not indicate the Bosch brand. What do you guys think? Any Help? Last edited by bobbyz; 09-29-2007 at 10:50 PM. Reason: add title |

you might have a clogged egr tube or bad egr valve. On my car, the tube was clear but the valve went bad.

Thanks for reply
Is there a way to check egr valve and tube or should I just replace them? Update: I just changed the 2 motor mounts and the transmission mount. Rough idle is gone and the car does not shake anymore. P0173 and P0170 codes are still there. |

usually the tube gets cleaned; the valve may have to be changed. do a search in the ml forum-the ml320 had the same engine & the techniques are described there.

thanks.
im trying to remove the egr tube. but for some reason i cannot. i did remove the 2 bolts which connects the tube to intake manifold. do i need to remove the egr valve first? btw, i did search the forum and could not find how to remove the tube. |
