P2285 = Injector Control Pressure Sensor Circuit Low Voltage

Probably the ICP sensor is going bad. There's a couple of threads on that in the tech folder: https://www.ford-trucks.com/forums/3...ch-folder.html

 

So how much is this going to cost me? Can this cause low power when cold because I am experiencing that.

 

I think the sensor can be had for around 100 bucks from partsguyed, who is a site sponsor.

 

Code P2285 Injector ctrl pressure sensor circ low. I found this post:


Yeah I pulled the code P2285. ICP low value. I looked around the internet and there was a TSB:

ICP/EBP Sensor Repair Kit:
Both PowerStroke engines may exhibit codes related to the ICP(7.3: P1280; 6.0: P2285) and/or EBP sensors (P0472). If these codes are present, clear them. Start the engine and wiggle the sensor connector that matches the stored code. If the code returns, replace the sensr connector--P/N 3C3Z-12224-BA for 94-96; 3C3Z-12224-AA for 97-2004. Broadcast Message 1078/SSM #17573.

 

Well, I got curious and unplugged mine and here's my experience. No significant changes to the way it ran except maybe a little rougher idle on cold start and a little less power until it warmed up. made a 15mi trip (each way) to work (mostly 55 and 65 mph). shut down for 15 min. Restart, ran well, check engine light came on when accelerating up to speed first time on return trip and stayed on. When I got home my mileage on the dash display was 2.4 mpg higher than normal for this trip. Broke out the scanner (Innova 3150) and got the following report:

Plugged EGR back in and erased codes. So I learned if I just unplug it, I'll be driving an very nice truck with the MIL shining at me. not liking that. Might have see a small increase in mileage (if you believe that lying gauge on your dash) would have to check on that further. More fussy on cold start which is a small annoyance already. So for me, it's staying plugged in until I can try some of the other stuff that goes along with disabling EGR that I've been reading about in the TECH Folder. Not sure why I got the code for A/C demand, I never saw that one before or since. Kinda weird. Also if you notice, there is a code for EGR flow. seems like that might be hard to get around without some software tweaking.

 

It's funny you posted this thread when you did because I was wondering about unplugging my EGR last week due to problems this system "seems" to cause. So I cleaned (it was REALLY gummed up) it as good as new, installed it and then unplugged it the next morning. So far my truck actually seems to be running a little better, maybe it's just me. I've driven it for three days and no CEL.

What i'm really interested to see is if my mileage improves as mentioned earlier. My truck only gets about 12mpg, so a 2mpg increase would be nice (especially now days!). I filled my tank two days ago and when I do my next fill I'll do a manual mpg calculation since I don't trust the lie-o-meter. I'll post those numbers for you when I do.
