My 09 ls seems to be throwing up too many codes for everything here to be going wrong at once.
I had a tire separate, and it took the inner fender with it. When I pulled over, it was wrapped around the axle/ suspension. Nothing looked damaged so I put the spare on and drove home. Everything seems fine, but, but about a day after I put new rims and tries on it a few days later (it was already planned, so I wasn't too bent out of shape about the separated tire) it started throwing up trouble codes left and right. I tried resetting the ecm and they come back as soon as the car starts moving again.
O'Reily's didn't give me the specific codes I had, but had mentioned the o2 sensors and the maf. I dug out my pos obdII scanner and got the codes, but it doesnt show the last digit of each, but from reading through the list of dtcs, it looks like they're;
P0031, P0032, P0051, P0052, P010?, P013?, P014?, and P044?
Would the tire have anything to do with this, maybe having knocked a ground wire loose or something? Could all these things really be wrong, or is there just a simple solution(hopefully). I need to get this taken car of, my inspection is up this month, and I can't get it inspected until there's not CEL.

Looks like you blew the Exhaust voltage fuse. Check in the underhood fuseblock. This fuse supplies voltage to the HO2s and MAF sensor plus a few others like MAP and intake temp

I had read that on another site. I thought I had checked all the fuses before, but I guess I missed that one. Went out to double check, saw it was blown. reset the ecm and let it run for a few minutes. Seems to be working now. I have to go pick up my fiance from work here in about half an hour. Will report whether the MIL comes back on.
Thank you for the help.

Well, down the road and back and no codes. Thank you Coby for that bit of knowledge which has potentially saved me a ton of money.

I think you broke one of the two engine grounds or both, the one in front where the transmission and engine bolt together. This is the ground for TCM and ECM, also for fuel sending unit and a bunch of sensors too.

Checking for power to the ECM is easy. Get the wiring pinout for the ECM, find the power and ground wire and use a volt meter and connect leads, will tell you if you're getting voltage. Sounds like a ground to me, but could be the ECM going out.

If you read codes ECM has power. Pull the fuses one by one check them for continuity and re-install flipped from original installation. This cleans contacts and seats in different spot. Especially the ECM/TCM fuse in the BCM fuse block.

That doesn't mean ECM is getting power. OBDII has battery power all the time. You need a CANDi ready scan tool.

MAF sensor gets its power from ECM, if you have the 10 Volts there that means ECM is powered up.

Right where the transmission meets the engine in the front is Ground 105.
