P0131 Code...what to do?

[Stormtrooper77]

I just took the car in to the dealer because my CEL was coming on and going out every so often. P0131 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 1) (according to the code list on this site) is what was revealed. Do I need a new O2 sensor, new battery or shell out the $200 - $300 to get it looked at and fixed?

New sensor. You can even get a Mazda OEM universal replacement part that is cheaper than the Protege OEM O2... The part number is FSD7-18-861A, here in Qc it was 95$ instead of 200+$ ! Other that the wire color shceme that is a diffrent and that le length of the wiring is slightly longer (use some tie-wrap if you don't want it to hit the rad's fans!) it's simply perfect!

That's what I did when I had the same code last spring and my car have been running with this part for the last 6 months and everything is as it was before...

BTW, I received the info about the universal part from someone I know who works Parts in a Mazda Dealership.

Where does this sensor get installed (location)?

It's the primary O2 sensor in the exhaust manifold.

Hahaha! Got it. By the way, my car has been smelling really gassy on and off. Any connection?

Yes..Its likely running way rich due to the faulty sensor.

I got this code this week......I like the price of the Generic O2 sensor has anyone else used it on an MSP?

I did for mine and I also know a couple of other owner up north here that did too following the recommendation from our source at Mazda...
