lonesta5 Posted July 26, 2006 Share Posted July 26, 2006 Code P2623 - Injector control pressure regulator circuit open. 2003 6.0L Powerstroke gets this code ONLY when a Superchips Flashpaq performance mode is installed (Tow-Safe, Economy, or Performance). When code is cleared, it comes right back. Has no actual driveability symptoms, CEL light does not come on, only clue is the P2623 code being stored. Truck runs great. When programmed back to stock, the P2623 never comes up. BTW, the truck has 06E17 factory flash installed. Any ideas?? Quote Link to comment Share on other sites More sharing options...

lonesta5 Posted July 26, 2006 Author Share Posted July 26, 2006 Take the program out! /forums/images/%%GRAEMLIN_URL%%/rofl.gif ... and I thought you were onto something. But seriously, now - any thoughts why it would show up now when it didn't before the 06E17 flash? Quote Link to comment Share on other sites More sharing options...
ktmlew Posted July 27, 2006 Share Posted July 27, 2006 The 06E17 flash made serious changes to the stock program. Apparently it isn't compatible with the power programer. Far as I'm concerned, messing with power-adder's on these is like giving your pet monkey a hand-grenade...it's bound to blow eventually! /forums/images/%%GRAEMLIN_URL%%/poke.gif /forums/images/%%GRAEMLIN_URL%%/hitthefan.gif Quote Link to comment Share on other sites More sharing options...
lonesta5 Posted July 27, 2006 Author Share Posted July 27, 2006 I agree in principal, thanks for your input. /forums/images/%%GRAEMLIN_URL%%/smile.gif But I get significantly better fuel economy when I drive light-footed using the performance flash. And like the crispy-brisky pickup out of the hole. Just trying to chase the cause of the open-circuit ghost that comes & goes just long enough for the PCM to set a P2623 code.

Jim Warman Posted July 28, 2006 Share Posted July 28, 2006 Obviously, the problem belongs to Superchips - might it be better to ask them for a solution? Bad enough that all the "yayhoos" think everything is the trucks fault and their mods are Gods gift... Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted July 28, 2006 Share Posted July 28, 2006 Is this a customer's truck or a personal truck? Quote Link to comment Share on other sites More sharing options...
lonesta5 Posted July 28, 2006 Author Share Posted July 28, 2006 My personal truck. Superchips says that something must be wrong with the truck, "nobody else has that particular problem" (the P2623 code). They think that some sort of existing weakness in the truck's system shows up when their program is flashed into the PCM. It's the open circuit code that puzzles me. Because the code is apparently set in a 'blink' rather than in a sustained failure, because a sustained open circut would certainly cause the truck to be DOA or have driveability or idling problems. I'm guessing either an erratic IPR itself or a connection problem or chaffed wire to the IPR. Remember, this is an '03, so that stuff is a little harder to get to.
