i bought an airmass intake and throttle body spacer and had them on my truck for about 2 weeks. Then I got a SES. it was insufficient egr flow. I am wondering if it is due to the intake or if anyone knows a possible fix. Thank you

 

Sounds like a classic dpfe sensor issue to me, depending on what year your truck is, it has extended coverage per a recall/bullitin of 2 years/24,000 miles past your base warr....

 

its an 01 with 40k on it. so should i take the parts off and go to the dealer?

 

Just drop by the dealer, they can run your vin, or post it here, and i can run check on it, and save you the trip possibly...

 

for what? i will post my vin on here instead of going to the dealer. i also noticed since getting this code i have gotten way worse gas milage. im talking 300 miles to a full tank of highway driving. is it anyway related to the p401 code im getting?

 

Well, now that i know what the code is, yes that is a dpfe code, and could affect your milage, don't know how bad though.... It will more than likley be a covered item, now you need to go to the dealer and have em check it out....

 

ok thanks man. i know alot of people at ford and ill just get a new sensor and throw it on.
