A couple of days ago, I pulled the codes when i noticed i was getting crappy mileage. I got a code 31. For the full details, check out this thread.

Since it was a code 31, which points to the sensor, not the valve itself, i decided to change that first. BTW, I used a multimeter to check where I was getting voltage (A very good tool btw for diagnosing things). I got a new sensor from Ford for 52 dollars. The parts guy messed up my order so I ended up getting it for 31. I put the sensor in and no more codes, except my car started hestiating around 1-2k RPM when warming up. I figured this was probably the valve itself, so today I took that out and cleaned it with carb cleaner. No more hesitation. All is good. I've heard that this is a temporary solution, and that eventually I will need a new valve.


Just wanted to let you guys know, because there was someone that has been living with this code for a year.

Glad it's fixed, and this is also why i got the egr simulator, and ditched the whole egr system.
