It shouldn't be. But it thinks it is for some reason unless you have a code. I'm not familiar with F150 3-digit codes, but on the Mustang a code 31 will turn off the function and flash the CEL.
That's why i suggested to pull the plug off the sensor. That should generate a code that tells the computer to turn off the EGR function.
This is pretty much a "try and and see if you get any results" sort of thing
Okay cool will try after work. Where does the "vacuum leak" take place if an egr is stuck open? Is it where the valve attaches to the upper intake? Or is at the tube that goes from the lower to the valve? Reason I ask is because if the valve WERE stuck open (I dont think it is) wouldn't there still be a leak even with the sensor unplugged?
