Diagnostic Scan Reading P1209 code!
I just bought an 01 f350 7.3L dually back in march. I got it for a pretty good price and changed out a couple of parts to get it running like new. But I have this one code we can't figure out, it reads p1209. Something having to do with oil pressure peak fault. My question to you guys is, what would it more likely to be a high pressure oil pump or an ipr sensor?
Hope to hear from you soon guys thanks!

KE15 CONTINUOUS DIAGNOSTIC TROUBLE CODE (DTC) P1211, P1209
DTC P1209 and P1211 indicates that injection control pressure was above or below desired level under normal driving conditions.
Possible causes:
incorrect oil or viscosity
poor oil quality
gel fuel/no fuel
low fuel pressure
damaged IPR valve
high-pressure oil system leak
damaged high-pressure oil pump
damaged PCM
Verify correct oil quality/viscosity and correct fuel grade are being used for the temperature conditions.

If you have access to a scan tool, i.e. Auto Enginuity, I would monitor ICP pressure and ICP Duty Cycle % at various rpms and loads. This would give an indication as to whether the IPR may be sticking. A bad ICP sensor could also be giving a faulty reading. Check for oil in the ICP connector.

Then, I would look into monitoring the parameters mentioned and look for pressure increases to match a rise in Duty Cycle.

I have to look into it. So what will determine if its my High Pressure Oil Pump or my IPR sensor?

Response time. If the DC % rises faster than the pressure increase, then the IPR is sticking. If your DC % peaks with inadequate pressure, then you have HPOP volume or HPO internal leak issues. How does the truck run overall? Is it still stock, or modded in any way?

Its basically stock to me. All I've done to it is a str8 pipe exhaust and a K&N air filter. She runs pretty good I must say considering the 327k on it. Only thing that concerns me is a light sputter it tends to do at times. Mostly on take offs. Tends to somewhat lag a bit then out of nowhere it'll speed up and run like a champ. But other than that she's good. I do melon hauling with it and I average gross weight about 40 to 41k and these are daily hauls.

I highly doubt this truck has been chipped or programmed. Well atleast I notice no signs of it drive wise or under the hood wise

Interesting problem that I may be sharing. I have seen white smoke from my truck twice in about 3 years, so I doubt that has much to do with it, but it could have just been the onset.
I have noticed a lag in power and started watching the ICP reading on the Edge Insight digital guage. I haven't monitored the duty cycle % yet, but I'll start now. The truck is chipped with a DP Tuner and I notice the same behavior in other settings, but mostly in the stock setting.
The symptom is the truck is sluggish and has very little "get up and go" until after the engine has been running for about 7-10 minutes. I notice that when its just started up (worse in cold weather), my ICP pressure reading may climb to only around 1,300 or 1,400 PSI but when its warmed up it will climb to as high as around 2,800 PSI at full throttle.
After thinking HPOP problem, I checked under the hood and noticed some oil in the valley. So now I'm leaning toward HPOP leak. Does it sound like I'm thinking in the right direction?
Any help is greatly appreciated. Thanks
