P1211 and P0238

bordo380 · Jul 25, 2016

Diesel newbie here.
I got these codes on my 7.3 Excursion. After research I see that these are codes due to over pressure from a tune.
I do have a TS-P 6 position chip.
I guess I will clear them out and see if they come back. Any way to avoid these or is there an actual problem?
I was pulling my boat just cruising at 2k rpm. Not being hard at all. So?
It has 256k miles on it and I'm pretty sure HPOP is original.

Also my wasgate is making chirping sound right at the 3rd-4th shift as well as accelerating in Overdrive. Maybe this is the culprit.

Sorry for the book.
If anyone can offer advice it would be greatly appreciated.

Codes cleared and rolling along fine so far. Now to figure out waste gate chirp.

Those two codes are very common when you have an aftermarket tune.

P1211 means your ICP is not meeting the desired amount. This is usually due to the tune itself, a weak HPOP, worn injectors, or a combination of those.

P0238 is an overboost code. You can install an overboost annihilator and not have this come up again... https://www.dp-tuner.com/ford-power...ries/driven-diesel-overboost-annihilator.html

Justin I was also getting this code on my 97. I have new injector. New icp and new hpop. Once I installed new hpop it prevented alot of the codes but occasionally I still get one. I'm running TW tunes ( not happy with) could this cause it.

Tony does not stop the overboost codes, it is a soft code, the light will go out after a few minutes of driving at under 25 lbs. of boost. The ICP lower or higher than demanded is simply an HPOP that cannot keep up with demand. Same thing, if you stop demanding high ICP for a few miles, the light will go out.

Are your referring to the P1211 code?

Do you have a scan tool to monitor ICP and IPR duty cycle?

Still running stock injectors?

A chip with good 17º HPOP and decent injectors, in higher tunes, will call for more ICP than can be delivered. Expecially when you stick your foot in the throttle. Even on lower tunes, when WOT, will run out of ICP before you get through a 1/4 mile.

Remember, with a chip, you are going to substantially more than stock performance. If you don't have the mods to support it, the truck cannot do what you ask of it.

Bottom line right here...

Thank you that's my problem. Not sure any other mods I can do. Just need to live with it I guess. And yes running edge cts as gauges so can monitor .

New 160/30 injectors

Exhaust
Efuel
D66 turbo
New hpop

Are those injectors splitshots, singleshots or hybrids. Hybrids are the easiest on high pressure oil consumption.

Where did you get the HPOP from? Normally, a quality re-maned HPOP can keep up with 160/30's.

It's a MB pump

Haven't heard many reviews on those.

You can get a scan tool connected to watch ICP, IPR, and PW info though. That will show you what the pump is able to do.

What should those read if everything is working correctly. My cts will monitor those

Well, most tuners will normally call for around 2800-3000psi of ICP. So on a WOT run, you should be able to hit and hold around that number. If your IPR Duty Cycle is 65% +, that pump is doing about as much as it can to keep up. Monitor PW at WOT as well and see where it goes.
