To start, I have a 2005 Excursion with a 08/2004 build date and drive train with a full EGR delete.

The problem I am having is I am getting a check engine light constantly. I have the egr connected still sitting on top of the engine, I use an SCT to tune but even when going through the checklist and turning the egr off it throws a P1334. My Edge insight clears it, and it will not come on until I restart so it isn't too bad. I guess my questions are 1) is the P1334 causing me to loose any power and 2) even with my SCT showing egr off should I still be getting egr codes.

 

P1334 EGR throttle position sensor minimum stop performance. Throttle plate, actuator sensor.

 

I know that the code is related to my EGR delete. So what is the way to fix P1334 and now P0448? I guess I don't care about the codes as long as they don't cause driveability. At this point every thread I read gets me more confused.

 

It doesn't appear to be an egr delete issue. It looks like its more of a sensor problem with the throttle plate.

EGR codes that give you a light after they are deleted are normally for flow.

I'm guessing the actuator (throttle plate) either isn't going back to home position or the sensor is not working correctly.

 

Its the tuner. Normal. Call sct and they should help.

 

Well I guess I will give SCT a call. I hope that I can get something done because I don't want t have reduced performance. As of now i can reset the code and it won't come back until I shut down and re start.
