Help! 2005 Ford P2623 IPR

[fiffer]

I have P2623 which seems to be the IPR sensor. Is there a write up on remove and replace? Would you replace the IPR for a P2623 Code?

Thanks in advance,
Christopher

You really need a monitor. Read the stickies. What is the truck doing? It would be a good start to pull it and inspect the screen for tears, if you don't have a monitor. Youtube has videos, srmastertech.

I have a cts. I just replaced the glow plugs and glow plug relay for a cold start issue. If it is below 45 it won't start. I don't have any test time with it since replacing the plugs and relay but I think the problem still exists

Voltage seems okay so maybe the screen is clogged?

What are your battery voltages while cranking cold, ficm voltages koeo, koec, running cold. Also what is your icp readings cranking, and at idle?

FICM is great, I just did the bulletproof 6phase and my monitor never goes below 50(the max it measures) Usually the battery will dip to 11.3 or so but during normal operation it will stay around 12.9. I'll have to check on the ICP voltage when I get into the shop but I'm pretty sure it was within spec when I checked it.

If your cts has been updated, you can read icp pressire now. Much easier than the voltage reading.

IPRs rarely fail on the electronic side but anything is possible. You may have a chafed wire, bad connector or an IPR that's failing internally. If the code sets all the time the problem will be easier to identify. If it's intermittent you will need to do your tests while it's a no-start

The IPR is not too difficult to change but you need a special socket to access it without removing the turbo. If you remove the FICM and rear ficm mounting bracket you can get to it with the socket, a universal and a 8" long extension.
