Replace ICP sensor? Easier way?

[PDA1]

My 6.0 L EXCURSION is doing it's annual "surge & stall" routine and the P2285 code has appeared several times over the past 2 months or so.

I have to replace the ICP sensor usually once per year and I've gotten pretty good at doing it. (not that I want to)

Is there some sort of flexible extension tube that can be fitted into the ICP hole so the ICP can be remotely mounted and changed in minutes instead of hours? Perhaps an hydraulic hose with the right fittings on it? Or, would too much air get trapped in the hose and prevent proper operation?

Any ideas?

what year is your truck? 03 on the pump style or late build on the valve cover. i'm assuming its on the pump style in which case get it from the bottom. just remove the heat shied. and get it with a crows foot and a stubby ratchet. takes 10 minutes.

Not so sure about 10 minutes, but getting it from under the truck is easier, if you have to replace the connector, then you need to do that from above.

thats how flat rate works. it only pays one hour under customer pay, even less under warranty. i've done well over 30 of them over my career. icp out and back in, in ten minutes. replacing pigtail is a little longer

I've replaced 2 of them so far and did both from the top.

Since I don't have a lift I can't get it from under the EXCURSION (2003).

An hydraulic hose maker is making an extension for me so I can thread the hose into the port and then simply screw the ICP into the other end of the hose. I'm sure I'll have to replace the ICP next year so that's why the "quick change" idea.

When replacing the ICP from the top too much stuff could/can be damaged (eventually) so that's why the hose is being configured for the ICP.

You men have any opinion about my idea with the hose?

The pigtail was replaced 2 years ago.

If there's a way to bleed the hose it might work, but chances are there's going to be air in the line skewing the reading. I know that the ICP's are a weak point on the 03's, but I wonder why you are going through one per year? Maybe look into a better insulation for the sensor? Is your oil temperatures getting too high causing premature ICP failure?

[PDA1]

The oil temperatures are usually around 195 or so.

I figure when I first install the hose that I'd add some oil to the hose to displace any air.

What do you think?

[strokemyego]

completely agree you shouldn't be going through an icp sensor every year!

[PDA1]

What's the solution?


The ICP failure this time follows the usual route- initial P2285 code after surging several times. I clear the code and then maybe a few weeks later the 2285 happens again. The surging and then sometimes stalling gets progressively worse after about 2 or 3 months. Then I replace the ICP.

Any ideas?

Maybe the ICP pigtail needs to be replaced again. I have seen pictures of a failed replacement (which looked very bad) maybe yours is too? Is the heat shield in place?

Honestly, I carry a spare ICP sensor with me (ok, it's an older one which I KNOW will work to get me home). Maybe replace the pigtail again and be sure that all the insulation is in place.

Oh, and 195 EOT is pretty good!
