My ICV at key on engine off is 0.0v. It will stay there after I start the engine (quiet injector sounds) and until I drive away.

It will read normal, and then every 15 minutes or so it will fluctuate, even at a stedy cruise, sometimes going down to zero. The truck lacks power and sometimes bucks when this happens.

The ICP and IPR readings are normal during these intermittent episodes.

After searching and reding through a dozen threads, am I right in assuming that if ICV is reading this way, that the ICP sensor is bad? or could it be something else?

 

Have you checked the connection to the ICP? Having any extra oil leaking from that area?

Sadly, your ICP is under the turbo.

 

I know its under the turbo and I have not checked it. It was replaced under waranty waaaaay back in 2006.

So if the ICP starts to fail, this is what it looks like on the SGII?

 

Actually, you are the first I have seen notice the ICV readings doing some fluctuating.

I'm interested if someone else can chime in here on this.

But first blush would be to check the plug for oil. See if it is the issue. Then, I would be leaning towards a new ICP.

Thanks for using that gauge. I had a hick-up one day while towing and it was mentioned it could be the ICP. It hasn't done it since. Now I'll add ICV and look a little closer.

(By the way, I figured you knew where our ICP was, I was just saying. You have been here long enough!!!!!! LOL )

 

bump...................................

 

just received the ICP sensor from Toulsey that I purchased. I'll install it in the next two days and report back

 

is your refresh rate set to fast on the sc2?

 

I just met a 2003 6.0 owner this very morning having ICP issues, He is going to call me with which code he is getting.

He was wondering if it could be replaced for less than $500. I said sure, we could get it out together and replace it. We probably wont get to it until the 28th or so.

Look forward to your swap story.

Oh, if you could post the part# and if you are changing out the pig tail for it also? Thanks.

 

SEAN I got at mine from Top

IDK How they get from Bottom my trucks lift makes it hard but I couldnt figure how to get in there from Bottom so I said screw it and went top route and started pullen parts out

I took out the Air filter and Air intake also the Coolant Bottle and FICM

I Did NOT change the Pigtail just cleaned it with Carb cleaner been fine since

Got the ICp from international for 120.00 IIRC

Heres my thread has Part#s and sockets size I stoped at Sears on the way back from international and Got a Really Deep Socket worked great and to put new ICP in I stuffed Paper Towel in the socket to Hold ICP out far enough to get it started back into the HPOP Cover

Got R Dun today. Followed the write ups in the tech file. Took about 2.5 - 3 hours. Pigtail was a little oily so I took it apart and cleaned it with some spray electrical cleaner and let it dry out.

ICV is back to within normal limits on the Scangauge II, the truck drives much better, there is much less unburned diesel smell, and MPGs have gone back up to normal.

 

Good to hear.

Already noticed rise in MPG? That's quick.

 

Yes it is quick, but I drive the same exact route to work every day for the past 9 years, so I reset the lie o meter and drove the route, and it was back to where it usually is.
