so lately when i start my truck and start driving it runs really rough until it gets warm and when it does it throws a check engine code witch reads a high?low injector presure when running and i don't know what i can do to stop it some help would be great

thanks guys

 

High to low side fault?

Or P1211? Whats the specific code?


First off, you should not drive your truck much and be very easy on it when cold. I dont even move my truck until its at 100* on the oil temp gauge.

 

umm not sure off hand what the exact code is and its not that its cold out side its 60 degress out here but the engine temp is still working up tell full running tempeture is what i meant i can check later and try to get the exact code i belive it sadi injector cotrol pressure high/low (engin running)

 

Check your oil. Has it been changed lately? Part of the injection system on the 7.3 is driven by the oil pressure. I was ready to send out my injector pump to be rebuilt, but someone told me to try changing my oil first. It worked, and the truck has run perfect ever since!

 

What did you do to ur truck now? plus you are losing ur license so Y does it matter.... Jk

 

hey now phill ill have it back when you get back and i will try changing the oil i know its a little old

and the codes that i had was
P1316 injector module codes detected
P1211 injector control pressure High/lower then desiered (engine running )

 

The P1211 is somewhat normal on a tuned truck, are you driving it in the agressive tune all the time?

The P1316, clear it and see if it comes back. It could be a wire harness issue, or it could be something else, but start there.

 

ya its on the aggressive setting all the time and i will clear that code and seit does and let you know

 

if your driving around in the agressive tune all the time make sure you are giving plenty of time for warm up.

 

okay i do sometimes but i will make sure i let it warm up all the time now thanks CSIPSD
