Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Can you tell us the Year, Make, and Model of your vehicle, along with the engine size?
If you have the VIN handy, that would be good.
I am going to have to open the question for another expert to help you, as I have lost access to my information database. I hope that someone will be along shortly to help you.
Thanks for your patience.
I HAVE A 2005 GMC 2500HD WITH A 6.6 DURAMAX VIN 1GTHC23205F922193
WITH 2 FAULT CODES.
P0202 INJECTOR 2CONTROL CIRCUIT
P2149 INJECTOR POSITIVE VOLTAGE CONTROL CIRCUIT GROUP2
WHAT IS WRONG?
I CAN CLEAR THE CODES WITH MY HYPERTECH 3 BUT THE CODES CAME BACK
SO I THEN CLEARED THE CODES AGIN AND SET THE SETTING BACK TO FACTORY SO FAR OK WILL THAT HELP?
I got access back to the system and have a TSB (Technical Service Bulletin) for you. Depending on your mileage, you may be able to get this repaired under warranty. I would check with a dealer and see what you can work out, especially if you have it serviced there on a regular basis.
Sorry about the size of the files (below), but this is a big on. The images are in the same order as they occur in the text (the first file).
Please let me know how it works out.
Take Care, Greg A.
