H3 Engine code PO69E on Alpha

[Ghostbuster]

Hi guys, I’m looking for some help with this engine code. PO69E

The H3 idles weird (like almost dies) at start up for a few seconds and then it is fine.

It said the fuel control module is throwing the code. I googled it and it said it could be like 6 different things.


I don’t really have a mechanic shop I trust around here and I really don’t want to go to the dealership.


Any help is appreciated.

I just put a new Vapor Canister Purge Solenoid on it and it seems to have resolved the issue. The check engine light has not come back on after driving it for a few minutes.

Hopefully this fixes it and this info may help someone in the future.

That's an annoying code. It really just means "ask the other guy". The fuel pump module asked the ECM to turn the light on. To see what's actually wrong, you need a scan tool that can talk directly to the FPCM. I got the same code when I had my ignition on to bleed my brakes while my fuel tank was still removed. FPCM was freaking out because it couldn't see the pump or the vent solenoid. Everything went away when I finished putting the truck back together.

If it comes back, you'll need to find someone with a Tech2 or similar tool to pull the actual codes from the FPCM. Hopefully it's fixed and you won't have to deal with that headache.
