Archived 05 lost power

[NFranco]

I have an 05 6spd running fine then all of a sudden lost A/C, then lost power in

6th gear. I can run 1-4th and travel 60mph but thats it. Got the following

trouble codes P0299, P0647, and P1246. What are the codes, and what should I look for, appreciate any help.

299 is a "Supercharger underboost"



647 is a "A/C clutch relay circuit HI"



1246 I'm working on... its Chrysler specific...

Your truck has put itself in "limp" mode. Do you have any boxes on it? Limp mode will clear itself out if the conditions are fixed and you start/stop the engine 3 times. You have to actually drive it between key cycles though. Either that or you have to clear it with an ODB code reader.

P1246 is a "alternator load input"...

Not sure what any of that means...

I'll check this out, thanks for the prompt response.

I limped the truck to the dealer... it turned out to be a shorted out #3 fuel injector, $1000. 00 parts and labor ouch... ... .
