I don't understand what's going on. I replaced the upstream 2x already. Took old one in saying the had a manufacturer defect got 2 new ones. Got a new maf. I cleaned battery post, grounds redid my wiring. Clean air filter, fixed exhaust leaks. New spark plugs gapped to .52... I don't understand what's going on.

My car says it is federal emissions but the car is rigged for California. And I only have 2 sensors not three. 2006 Mazda 3 2.3 manual.. has anyone has this issue before?

DownerMazda you just summed up the total of your lack of getting training in a school by saying how crazy newer vehicle electronics are. They are a breeze to find and solve electrical issues if you know what to look for .
This OPS wiring is a mess of wires and is not something that shops do contrary to one member that say they would take it on. I am sure their shops insurance would have question if that customers car burned down because of a NONE oem wire repair. You may have read I recommend that the OP go to an Auto Electric shop and not a general service shop for the repair. Maybe you didn't notice the current state of DIY mismatch color wires and poor connections? :rolleyes:

Now where is that popcorn eating emocon?? LOL
When referring to nightmare electrical concerns I’m not talking about finding a short or open wire in a simple circuit. I’m talking more on the line of CAN-FD, automotive Ethernet, and other new technologies that technician is being introduced to for the first time, not just new or untrained techs. I have extensive electrical training and experience as that is my main job in the shop is figuring out electrical concerns that others can’t. If I was diagnosing and fixing this vehicle it would be repaired properly to ensure a robust repair and attempt to prevent future concerns. Your arrogance is almost sickening and I’m glad I don’t have to work with anybody in my shop that believes they are gods gift to the automotive industry.
