IPR valve bad or screen plugged?

I had just recently did an oil, and egr cooler, standpipes, and dummy plugs. I was getting a no start when hot. I also checked my STC fitting while i was there and it was done already. MY hpop screen was ripped, my IPR screen was fine. I changed both.

After i got it started and idling for a bit the idle changed and the hpop went up to 875.00 and IPR went up to 32.5% and threw a code p2284. I cleaned up the ICP and reset the computer and it started up fine again. Only when i put a load on the engine does the code come back and the same symptoms.

Here is the question. Will a clogged IPR screen and or a bad stuck IPR valve cause this condition? The truck ran fine before all this, only the no start when hot. If i'm gonna pull the turbo for the valve i would like to do this only 1 more time. Also, is there any way to clear the HPOP for any problems while i have the turbo out?

There was alot of crud around oil cooler and i used towels to clean the HPOP reservoir. Clogged IPR?

Thats an ICP circuit code. You need to check your ICP voltage KOEO, wiggle the connector while the truck is idling and see if it skips, may be a bad sensor or connector.

Sounds like a IPR issue. Pull the valve and check the screen for debris.

You can buy a special socket for the IPR so you dont have to pull the turbo
