I have a 2006 V6 mustang. I currently have pypes dual exhaust and a BBK CAI on it. Other than that, it is stock. It is currently sitting at a whopping 153,000 miles. The check engine light came on a couple of days ago, took it Autozone and they said it was the O2 Bank 2 sensor 1 (Driver side, upstream). I got the O2 sensor replaced the next day. Drove down to walgreens (5 min drive) after clearing the engine. Left walgreens and the light came back on. Went to autozone and they gave me the following codes:

U1900
U2011
P0174
P0171
P1000

I looked some of them up, but got a little more confused with all the different explanations out there on google. Can anyone help me diagnose the problem with all these codes?? I really need my stang to be back in good standings!

You need to clear the codes (have them clear them) and see what it does. Or disconnect the battery for at least 20 minutes.

Hopefully you installed a new OEM/Ford front sensor; other brands (such as Bosch) don't seem to work properly.

My engine light came on like a Christmas tree after starting it up last night at the rifle range. Will call my local repair shop this morning to see if he can get me in today. One 02 sensor was replaced 80K miles ago. Just one of those things when time runs out, engine diagram will light up. Love my sting.

Autozone or most any auto parts store will pull the code free-of-charge.

Yup, on Auto Zone Nuke. I just went out to the garage and turned the gas cap a few times and checked the oil. The engine light went out. Will say it was the gas cap for now. Nice to know maybe nothing major to replace. Thanks
