Hi Steve,

 

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.

 

Thanks

Hi again,

 

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.

 

 

Take Care, Greg A.

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?

Hi again,

 

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).
