351w 212 code


Finally got my OBD1 reader to work, had to run a ground wire from neg terminal to the small harness of the ECC port.

issues:
comes and goes, truck will start great, lower rpms like its settling then eventually start to bog down. (After about 1-3 minutes) When im driving i have to keep my foot on the pedal because it wants to die.

code results:
117: engine coolant temp sensor (code is now gone, replaced)
565: canister purge solenoid (gone die to air pump delete)
558: egr valve reg circuit failure (EGR deleted)

CM
212: loss of spout connection

KOER
998: limp mode
117: coolant temp sensor...

Can anyone tell me what this part is (connected to the dist) think it may be whats wrong, if not im assuming its the ICM, if not the ICM, possibly the PCM, the truck has a completely new distributor in it. I replaced the PCM about a month ago due to shift issues, i got the Cardone from autozone with the correct code from the original PCM to the truck, ran great for about 2 weeks. So im assuming that cant be the issue but im open to any ideas on it

What year truck, will determine where, ICM is located, your going to need more grounds/check that they are there, and/or put them there.

its a 1995, i know the ICM is by the PCM on the drivers side. Youre saying just test the wires to the ICM?

The rusty looking thing circled in red is the COIL. Replace with Motorcraft part.

No sir,I'm saying check all the grounds subford eludes to in his post #2 click here-->Looking for ground connections - Ford Truck Enthusiasts Forums

There are two definitions for CM Code 212: Loss of IDM input to EEC or SPOUT circuit grounded.

The most common cause is installing the wrong ICM on 1994 and newer trucks. You should have a black CCD ignition ICM. If you have the older gray colored Push-Start ignition ICM you will get Code 212. To further complicate things many parts books are wrong for this era truck including Ford. Trust me, you need a black ICM for your 1995 model truck.

ive also heard TFI modules are a common problem and can cause my symptoms, but to my understanding the TFI and ICM are the same part no? Instead of being mounted on the distributor mine is mounted by the pcm

UPDATE:
new ignition coil in, there was ALOT of rust underneath the old coil, also G100 connection is rusted, cleaned up and reconnected,
the spout connector is original ford P/N E53814A624D.
the ICM looks to be after market, grey in color. Starting to think this may be the root of the problem. If none of this fixes the problem how likely is it that im looking at a PCM issue

that looks like rust on ICM, also, you can test it, (post #5) or maybe the parts store can, if its bad, tell them you need one for 95 Mustang GT 5.0L, and you will get the correct one, that rla2005 is talking about, motorcraft DY-1077, if your PCM connector looks like the coil and ICM, it may be good and rusty also, and could use a good cleaning.

Thank you! Youve been a huge help man.
pulled the PCM out a few days ago, it was my first instinct since i thought the part may have been bad from the store, looks fine inside and out though there was some rust from the housing that came off onto the PCM when i pulled it out.

couple of questions if you dont mind;

1)if i but the new motor craft ICM should i buy a new heat sleeve with it?
2) can a bad ICM cause the on and off bogging down during idle and driving?
3) is it possible for this to put the PCM into limp mode?
4) with the 998 limp mode code is it possible that it may be the PCM alone?

A '95 should have a black ICM in it I think, that would explain the codes you are getting.

If money is tight and/or you need truck up and running, you can get, a parts store brand ICM, but get them to test it, before you leave, too many times we've all walked out parts store with a new 'un' working part, and not know, until we get home and try it...and back to store!
Dont forget the the heat sink paste(not dielectric grease) to put on back of new ICM.

lifesaver man, yeah i may need to throw an off brand one on it so this helps out ALOT. Wish i could replace everything with MOT but thats a little rich for my blood at times. I really appreciate your imput and ill post back with results incase anyone else is having this issue
