i've got a 2002 F150 4.6 V8 with 78k miles on it. Check engine light came on recently, i've put a fuel additive in & ran it through a tank, changed the gas cap and the light still comes on. any ideas gentleman and or ladies?

the truck still drives very well, so there doesn't seem to be a major problem

thanks in advance

 

Take it to your local parts store. THey can probably ck it for you and tell you what is wrong.

 

found it the problem is my EGR valve. is this something i can fix or does it have to goto the dealership or shop?

 

you can do this yourself is the egr bad or what is exactly the problem egr valve,or egr sensor?
let me know

 

I don't know what the problem is, but I LOVE that picture you got of the ladies on your truck! Very nice!

 

it is the sensor

**thanks for the compliment on the picture, gotta love it when hooters has a carwash

 

How do you know its the sensor? Did you get a code? What code?

 

i went by autozone and they pulled the code for me, it only took them about 20 seconds

 

what was it was it a excessive air flow... or insufficient air flow....if so then it's an EGR issue... either with the EGR or with the sensor

 

if its the sensor its a GP Sorensen EGR Valve Position Sensor Part Number: 77911007. at about $52 at advance auto. hope this helps

 

Oh, great! Another AutoZone diagnosis.

At least they have a 50% chance of being right if they told you the DPFE sensor.

It's either that or clogged EGR ports which they cannot test since they down't know how. The ports and the EGR valve can be tested using a simple vacuum test.

Do you remember the exact code? In the form PXXXX
If you cant remember it, go back and get the codes scanned again, write down the code and post it here. We'll tell you what to do from there.

 

try to get the code

 

i will get the code when i get home, i've got it written down but didn't bring it to work with me this morning.

All-
Thanks for the responses, they are all much appreciated.

 

The code I receive is:
P0401
