Pushing 200,000 and the issues just keep coming. Today I changed the pigtail on my ICP sensor and it started fast and ran fine. Went to pick up son and started throwing new codes P0470 and P0069 and feels like the truck has gained 300#to GVW.

Troubleshooting previous issue I replaced IPR( made huge difference for 200 miles),pulled and cleaned EBP sensor and tube, egr cleaned, pulled MAP sensor tube cleaned it and the nipple in valve cover and replaced ICP. The turbo has been cleaned and was in good condition. I do have an exposed wire on glowplug harness but starts great, both wire assemblies have been ordered from tousley's.

SO now what?? just replace these 2 components as well?

All help is appreciated, thanks

 

baro/map dtc is a result of p0470 ebp.
one of a few things you may have miswired the icp sensor, yu have a failed or unplued ebp or epb pig tail. fix the p0470 and you will be fine.

 

Thanks for fast reply,
I matched wire location closely on icp but will check that Ebp pigtail. Three others went soft and showing so makes sense.
I'll let you know.

 

Here is an update. Confirmed icp pigtail wired correct, at least compared to OE. EBP harness and pigtail seem intact and connection is good. Cleared codes just got done driving hard 40 miles. This thing drove like a test drive! got me all excited again

Then as I was driving normally up hill to house, got a CEL plugged in OBDII. only code P0299 Thats the code that started the last 3 months.

Any way Boost was great mothing obvious to me. Im gonna clear codes, check vgt solenoid connection then drive and see whats next.

Appreciate any/all suggestions.

 

Thanks to cheezit,

changed out ebp, think its cured.

 

9.5 times out of 10, a P0470 code is repaired successfully by replacing the EBP sensor.
