Front O2 not reading

[FilmerDude]

My O2 sensor only reads .02 to .03 volts and I replaced it and it still shows the same readings. I am using ecu+ to read the output. Any idea what's going on?

Have you tried different mafs? I had the same problem where my 02 didn't cycle because of a bad maf.

Yeah I have another one I'm going to try. I'm thinking it was bad because I left it sitting out in the rain
