I changed the ICP, no change in symptoms and code came back so I changed the pigtail. Still throws the 2290 code. Truck runs good until letting off throttle to coast or stop then it has the heavy black smoke / no power. Usually I just get going, let off on the throttle briefly and it returns to normal. Then back to smoke / no power again sometimes the next time I coast, sometimes lasts a few cycles. Happens mostly when towing (about 8000 lbs). Drove 40 miles city driving last week and had no problems at all. Hook on the trailer and the symptoms come back.

Could the new sensor be bad?

Can I remove the EGR valve, cover the hole and drive the truck??

 

the P2290 DTC isnt really a Bad ICP sensor code

OEM Oil FIlter??????????????????????????????????

 

And OEM cap??

 

Very Very Slim chance here^^^





NO^^^^^^^^^^

even if you could that wouldnt help a HPO problem

you can unplug egr valve when the trucks turned off so its in the closed position but again wont help a HPO issue

Fix the HPO problem then if it has a EGR Valve problem then address it

 

Thanks Mike thats what I ment

Keep an eye on me

 

that's just one component for the mod, the other side has to be blocked off too.

check your vgt solenoid

 

yes all OEM and just changed all synthetic. (always every 5000)

 

So I wasted the $155 for the sensor and the $45 for the pigtail.

 

Don't know how to check this. I know where it is and I did clean the wire plug and wiggle the wires. Do I remove and see if it is sticking or moving freely, and clean it off?

 

Yes ^^^^^^^^the DTC/Code and symtoms returned and never got better

Plus you normaly would get a diffrent DTC for bad ICP sensor P2285

P2290 C O Injector Control Pressure Too Low Default inferred ICP is used, ICP is below desired pressure See diagnostic manual - ICP system.

I would deal with the P2290 DTC FIRST before you worrey about EGR Valves and VGT Silinoid/Turbo

Deal with what you Know is the Obvious problem P2290 Its a GIVEN

Your 110% shure Oil Filter CAP is OEM???????????

Odds are you have a HPO Leak


The First step to diagnos it is verify GOOD LPO Flow to oil filter housing by pulling the Filter out and hold the drain down inside filter housing with a screwdriver it should fill fast as someone cranks the engine over

You cant make HPO if the LPO side is Starving the HPOP

next would be an Air test of the HPO system or Pull IPR Valve and check for damageed screen on IPR

 

P2290 means that ICP desired pressure is above actual ICP pressure for X number of seconds while the truck is running. I'd pull the IPR valve and check it for a trashed screen. You could also have an STC fitting going bad. You need to find a way to monitor HPO pressure while driving.

 

Thanks npccpartsman and Blade

Looks like I have to look up/ learn a few acronyms and see what I am able to do myself...

I bought the truck used, the previous owner had the dealer do all the work including oil changes so as far as I know the cap is OEM.

I will try the drain test.

Could someone point me to the IPR? I'll try a search too.

heres where your IPR is

But depending on year ICP maybe in passenger side valve cover but MY03 is ICP under turbo too
