p0446 and p0449

Question

I have a 2009 GMC Sierra 5.3l throwing P0446 and P0449. First off can I fix this on my own? Second, How much damage am I causing driving with these codes? Need some help and quick.

Sorry I can't help you with these. But, the guys in the "ask a GM technician" forum are great. You might want to move this question to that forum and I'm sure you'll get some quick answers.

I will. I just need a couple weeks for the cash flow to start buying parts. I'm screwed if it's a ground, electricity and I are not friends.

My 2010 at 50,000 threw the same codes, same problem, same kit, only had the dealer take care of it. Basically cost me an extra $100 vs. doing myself. Now seeing a video like this one, maybe I would have made the time to do it myself instead. I also drove a couple thousand miles before finally getting the work done with no problems.

I'm at the same mileage. How much did they charge to fix it?

I don't have my receipt anymore. I think it was a couple hundred. Had it done when I went in for oil change. Only thing I've ever had fail (so far :fingersx: ) on this vehicle.
