These codes are telling you that there is a problem with the ECM harness, targeting the #2 and #7 injectors. It's time for the fix. You can do the ice-pick, but in my opinion, that's only temporary. The kit from the dealer to do it right is around $250. I just had mine done 2 weeks ago.

where did you find info on the harness being cover under warranty? I have an 06 lly completely stock, that is having the same problem and throwing the same codes, but my dealer says only lubricated parts are covered so the wont do it. Thanks in advance for your help.

if you are having problems with this issue call the gm customer service number and you can get it cleared up with them. i dont have the 1-800 number but i am sure you can google it and find it... i do know for a fact this issue is a warrenty issue, just had mine done at no cost....

2004.5 GMC 2500 HD Duramax:
Here we go again. January 2005 had P0202 (Injector Circuit Malfunction-Cylinder 2, also P2149 (FICM (fuel injection control module)...New engine wiring harness installed under warranty (32,000 miles)...Doc ID# 1566267.

Today, it is de javu all over again, though MORE THAN 5 years later, 98,000 miles, same doggone P0202 & P2149 codes. Will be interesting what the dealer tells me tomorrow.

Warranty question?

if you are having problems with this issue call the gm customer service number and you can get it cleared up with them. i dont have the 1-800 number but i am sure you can google it and find it... i do know for a fact this issue is a warrenty issue, just had mine done at no cost....
I notice that yours is a 2005, mine is a 2004.5 GMC 2500HD Duramax 6.6L, Allison tranny, thus past the 5 years on the warranty, has 98,000 miles, I had exact same codes in January 2005 at 30,000 miles and was under warranty...seems a shame this keeps occurring.

Guess what I was getting to, were you past the 5 year warranty when yours was done at NO Cost to you.

Thanks,

RalphV

2004.5 CODES PO202 & P2149/98,000 miles

Same codes as 2005, new engine wiring harness at that time, this time was 90 degree connectors for both #2 & #7 injectors, also glow plug control module replacement, then should be good to go. Dealer found no chafing on alternator bracket, a good thing.
