Hey the site forum, I'm new to the site. I have 2 codes that popped up. P1800 and P2A00. Can anyone out there lend some assistance on where to locate and fix before taking it to the stealership.

Well, I believe I found the issue for the P1800 and hopefully the other code is fixed with this find too. I found a small air line hose that was broken.

Fxlr8, thank you for your response. I found the same info. I hope what I fixed will do the trick, so far the light has not come back.
