All codes went away after some skinny pedal action while merging onto roadway.

I suspect maybe a wire-harness needs some attention ? Somewhere?:_thinking

My guess...CPU brainfart...if it comes back, I'm wrong...:_wrench:.:yesgray:

X2

That's a lot of codes isolated to a small group of sensors. Sounds like a CPU brainfart to me too.

Clean and check battery terminals, I had all kinds of codes pop up after I installed a new battery.....cleaned crude off the terminals and viola no codes!!!

Codes are back on. Battery and terminals are new .

I would check the wiring going to O2 sensor.. If a couple wires melted together and are shorting it could cause that part of the ecm to freak out.

Please forgive the obvious question but is the battery installed with the proper polarities?

Forgiven.

Battery is properly installed. I will check the o2 sensor wiring again.
