SES Light

shadow stang · 01-28-2005, 11:27 AM

Has anyone experienced this? My SES light came on after I had a 75mm Throttle Body and new Plenum installed. I have an '04 GT.

normally the light should go away after driving it for 20-40 mins. try resetting your ECU overnight (of course you'll lose your radio presets):
-unhook battery
-turn on headlights (to drain any residual juice in the system)
-let sit overnight
-next day, rehook battery. turn off headlights.
-start car (will run and drive ragged at first until the ECU relearns)
-after warming up, take a casual drive (to allow ECU to relearn)

I have a CAI, 70mm TB, and plenum on my 02 GT - no light.

Man, I've had the damn light on for 2 weeks! I'm taking it back tomorrow to the shop that did the work so they can put a scanner on it to clear it up. Just wanted to see if it was normal or what. Thanks for the info though.

See what's weird is that is did come off, I went and raced it. Then the next morning it was back on and hasn't come off since.

Sorry.
2004 Mustang GT, 5-speed
The code that keeps popping up is P2272 and it says on the shop's book that did the work to SEE SERVICE MANUAL.

I just tried to look up that code and it's not listed. Are you sure they gave you a correct code?

I'm with you on that one. I can't find it anywhere either. If I go to Autozone, do I just tell them to run a scan on it? And it's free? Thanks for helping me out. I'lll also call the shop tomorrow again to make sure it's the right code. They wrote it down as P2272.
