check engine light.
Hey all. I got a question...
My buddy had a 1990 Ford F350 460 5 speed. It has a check engine light that pops on and off every now and again. It seems to only come on once the truck is hot, no unusual pattern......
how might I pull the code on it? Obviously a code scanner but where do you connect it? Thanks in advance
. I've worked on ford trucks for years so I am very mechanically inclined but pulling a code is way easier than searching for days to find the issue.

Sounds like the EGR valve but can hook the code reader up near the air filter box on the LH fender apron.
To check your codes go to one of these links below:
This is good for the KOEO test:

hey guys I found the problem! pulled the codes at autozone with a scanner and it turns out it was code 119- Low VAT sensor voltage. Changed sensor old one was covered with oil. New one; Runs awesome . The VAT from what I understand measures the incoming air temp, and adjusts fuel mixtures to suit it. Thanks for all the help guys!
