My Mazda keeps throwing check engine codes high voltage low voltage no voltage no detection on O2 sensors and then sometimes they don't read it all

Gonna need a lot more specific information. But the obvious question is, have you checked the O2 sensors wiring? Which sensor is it complaining about?

dannyboy26001

Every time I drive the car I get a different engine code sometimes it reads low voltage on the O2 sensors sometimes it reads no voltage on the O2 sensors and then sometimes it reads high voltage on the O2 sensors and then it also throws codes dealing with the sensors underneath the intake it's a different code every time I hook up my reader

The different codes I get is p0134 p0 130sometimes they say high voltage sometimes they say low voltage sometimes they say non-detection

So that bank 1 sensor 1 is your front O2 sensor. Sounds like it's very damaged, or the wiring to it is.
I wouldn't drive the car like this.

Specific codes please.

It's possible there's an electrical issue that's playing havoc with your systems, but lets confirm physical damage to each sensor first.
Maybe clean your grounding points and battery terminals just in case.

Well the two codes that it keeps throwing now is p134 p130 and then on both of those codes it tells me low voltage no voltage or high voltage every time I hook it up it reads different

i have had my rx8 for a few weeks now and i decided to take it out yesterday and it was misting all day. it started fin in the morning drove it to work still fine went to lunch still fine. decided to go to the store after work and the starter wouldnt crank so i bump started it to get it home i pulled in the driveway and decided to see if it would start again and it did iv had this issue in the past and it seemed to be fixed by a new starter relay but im staring to think other wise.

A little bit of mist wouldn't cause an issue for your starter. Would be either a bad battery or starter unit if its not cranking fast enough to start.

Could be a coincidence.
I had some weird fuel pump issues that seemed to occur in certain situations, but it eventually progressed to more random occurences.

Check your terminals, they tend to stretch.
Wouldn't hurt to shim or replace them if you can move them by hand.
