P0031 Front oxygen (A/F) sensor heater circuit low input this is what it is but what does it mean exactly and why would it occur....no new mods lately, I'm at stage 2 with an SS protune, am about due for an oil and tranny fluid change but not sure if they relate, just wanted to give some background info......any help would be super thanks!!!
Nasioc said that it's either a wiring problem and/or sensor related.... so just looking for more input before troublshooting...
I'm stumped as well. One easy thing you could do would be to unplug the connector and blow inside each end of the connector and make sure it is clean. You can also give a gentle tug to each individual wire and make sure the pins are tight in the connector. Also take a look at all of the wires. Look for anywhere that the wires may be pinched or may have rubbed through. If all of this turns out okay, it may be the sensor. Hope this helps
plug connectors? could there be an 02 sensor problem with a stage 2 set-up?....thought the sensors were turned off?....good news is I just passed emission before this happened...:sx:
The front O2 is not disabled in any stage as it is used for closed loop feedback. I'm guessing you either have a pinched/melted wire, a loose sensor, or a bad sensor.
I reset it last night and it came back immediately when I started it up this morning I'll check it out thanks Moose
