Ok, I posted before about my daughters 97 626 shifting hard and the engine light being on. Maybe they are related maybe not. Took it to Autozone today and had them run the codes.

We got
P1130
P1131

Along with a whole list of things that these codes could be. I am leaning towards teh 02 sensor husband is saying a short.
Has anyone had these codes before? Any way I can narrow down this list?

 

Well, I found this site.

According to the codes both that I am getting when matched with Mazda is the O2 sensor.
We are going to try that first.

The factory manual says the following for the FS (ATX) engine:

P1130 indicates the fuel control system has reached its maximum compensation for lean or rich condition and the HO2S is not switching.

P1131 indicates the fuel/air ratio is correcting rich for an overly lean condition . The HO2S voltage is less than 0.45 volts.

Also says that the 2 codes are related to the Upstream Heated Oxygen Sensor (HO2S 11)
