Hello,

I have been suffering from the above codes for the duration of my ownership of my contour (4 months). I've cleaned the MAF sensor, IAT sensor, all intake ducting, new air filter, cleaned the throttle body/plate, IAC valve assembly, checked all vacuum lines for leaks, replaced the spark plugs and still the codes are popping up.

Today I decided to run the appropriate diagnostic DVOM test on my MAF sensor, which mitchell says should be reading .6-.9v @ hot idle. I did v-drop tests over the MAF's feed and ground circuits, as well as a live idle reading of the MAF voltage signal. It all checked out okay, so i'm starting the think the problem may lie within the EGR system, possibly a faulty DPFE sensor which I have yet to test. Has anyone ever had this issue before?

I also have a question regarding a linkage in my IMRC system.(images pertaining are below) I detached my throttle body for the above cleaning and noticed that an actuation rod was disconnected from it's respective bracket (bank 1's IMRC actuation bracket.) I also noticed that there's supposed to be a white plastic snap collar for the linkage, which isn't there. I've cotter pinned the rod to the bracket for a temporary fix but I have no clue where to find the plastic collar. Any ideas would be greatly appreciated, thanks in advance.



as you can see the rod is half on- half off, i'm worried the radius is making it's movement unstable and possibly stressing the IMRC control module.

 
No I haven't. I'm pricing them out online and will probably pick up a new one this coming week. I was getting 12v drops on the supply and return circuits, a good airflow signal voltage too. The only thing that seemed weird was on the MAF_V signal return circuit i was registering the A/C gen output voltage, ~ 14.8? is that normal?

Honestly, i've little idea what the normal values are. I'd search a bit more on that. Or hopefully someone else opines.

Read the last post it has a pic of what you need.

Thanks, I just picked up the clip from the dealer for $8.11, gonna install it tomorrow. I'm also gonna go after the DPFE sensor and T.P.S. to see if they're the culprit for either code. I have only looked at the DPFE through mitchell so i have a schematic of where it's at, but some hands-on experience wouldn't hinder my progress in finding it.

I was just searching around on the EGR system and noticed another mention of these "EGR passages" behind the throttle plate, which i've tried finding before. I removed the throttle body but found nothing. Could anyone possibly point me in the right direction?

I was just doing some reasearch and realized that Ford used this MAF sensor on quite a few vehicles, which means options :D. I'm a little concerned about pulling from a junk yard or parts galore, so i may just get it new online.

...later that day.

I went to parts galore this morning to see what my options were as far as doner cars; there were a bunch of contours, half of them had the 2.5L. A lot of the 3.0L taurus' and a few mystiques with the 2.5L Duratechs under the hood. Decided to wait and buy the MAF brand new after seeing the condition of the ones on the lot, but got some leads on other imperative parts.

I picked up a throttle body gasket and new PCV valve on my way home for $6 and cleaned the EGR channels, which were completely clogged. The hard startup, rocky open loop and rough idle have died down dramatically(which makes no sense to me because the emission systems aren't active during open loop or idle), but the CEL came back on almost immediately, which leads me to believe it's the MAF reference wire going bad. I'll have a new MAF ready for install next week, so i'll let you guys know what happens.
