94 F-150 codes?
94 F150 5.8L E4OD
I pulled the following codes from my truck. I dont know how long it has been since the codes were pulled, as I just bought the truck.
KOEO 111 System pass
CM 332 Insufficient EGR flow detected
542 Fuel pump secondary circuit failure: EEC to ground
628 Converter clutch Lock-Up error (E4OD)
I then disconnected the battery and allowed the truck to get up to operating temperature and got a pass.
The truck runs great, i just got back from a 600 mile trip pulling a 5k trailer, I got a check engine light a couple of times during the trip but it went right off.
Which ones of these are urgent, which ones are minor?
Thank You

I wouldn't worry about any of them. They were all in the CM codes, which means they are intermittent. The fuel pump code probably is due to switching tanks while the truck is running. I'd just check the EGR system for proper operation, and make sure the wiring to the transmission is clean and has good connections. I'd also keep an eye on things and see what (if anything) comes back up.
