I have had a nagging CEL P0175 for a while now. Well i bouight a new sensor a while back and it never fixed the problem. So the other day i took the UIM/LIM off to see if i had any vacuum leaks(and to give 'em a good cleanin'). That didn't fix it either, so i took the MAF apart and cleaned the element with a small brush and (cross my fingers) i think that may have done it.
When i was cleaning the sensor i took it out of the MAF housing to do so. When i did this i noticed that there are two elements. One of the elements had a nice shiny appearance to it, and the other was a dirty black color so i cleaned it up and they are now both shiny. Is the dirty elements maybe the cause of my problem? What i mean is...on the sensor itself is one of the elements for the front bank O2 and one for the rear?

Per TSB, some reasons for P0175.
P0175 - System Too Rich (Bank 2) The Adaptive Fuel Strategy continuously monitors fuel delivery hardware. The code sets when the adaptive fuel tables reach a lean calibrated limit.
Fuel System:
�· Excessive fuel pressure
�· Leaking/contaminated fuel injectors
�· Vapor recovery system concern
Base Engine:
�· Oil overfill
�· Cam timing concern
�· Low cylinder compression
�· Excessive engine wear
Powertrain Control System:
�· PCM concern
Induction System:
�· MAF contamination

I know all that in the TSB...i was mostly just wondering about whether the two seperate elements have any relation to the two seperate O2's..... PS...the CEL P0175 came back on this morning! lol

LOL. I hope you were kidding. If not, I meant send it to a shop to get a real time scan of the engine. Or get a scanner capable of real time scans so that you know what the different sensors were doing when the code was set (freeze frame) and what defferent sensors are doing during the drive (real time scan).
Also read this for Bank 1.

I was kidding man lol.
And yes...I plan on doing some datalogging when i get home. I have the SCT PRP, and the Livelink software...so i'll see what's going on in there this afternoon. I just can't imagine it being the sensor itself...it is only 2-3 months old. I'll go home and do that, and post what i see...
