Hey guys! I'm a new 8 owner, don't hate please I have the 4-speed automatic, only because I got it for a steal and every one where we looked wanted WAAAY too much for the car, this one has good compression but could use a tune up. Any how the CEL is on and we plugged a scanner into it and it shows that the rear O2 sensor is flat lined with no voltage at all, while the loop is closed and it says all other systems complete the tests, the car still runs fine starts right up with no issues and has plenty of power but is using way more gas than it should, I'm just unsure what to do, please help? The loop is closed and I read on another forum that if the front O2 sensor is bad the loop wouldn't be able to close, so with that said, any suggestions as to the actions I take from here? I know a lot and did a lot of research before getting the car, and it's throwing a too lean code because of the sensor issue. So should I'm thinking I should just replace both sensors with the OEM replacement and get a new cat and call it done, do you guys think that would likely fix my issue?
The rear O2 malfunctioning won't affect the performance of the car but if the wiring is good just replace it, the rear O2 sensor is cheap.
OK, just wanted to see if this was a normal thing, because I tried looking this up and every other thread I find says "low voltage" and mine says none whatsoever

This is a pretty good discussion on troubleshooting the various types of O2 sensors. Denso is the OEM O2 sensor if I'm not mistaken. I just replaced both of mine (doing a rebuild and one was bad), I found pretty good pricing on eBay and RockAuto.

I will probably order one from Rock Auto, I would prefer to go with the OEM because the Bosch or whatever I've just had bad luck with, they are kind of hit and miss
Search the web for a 5% discount code for RockAuto if you don't have one. If you can't find one, PM me.
Sounds good, hoping this will make the codes go away so when I'm finished paying it off In a month I can get it inspected and be done with worrying about that, then it's time for upgrades or just going for an RX-8 6 speed mt to make a project car
So I replaced the rear O2 sensor today and on the OBD2 scanner I have it still doesn't show any voltage for either of the O2 sensors, but my fuel trim leveled out perfectly, this is kind of funny to me, any suggestions? On my Honda civic it shows the voltages of the O2 sensors fine, but on my 8 it doesn't show hardly any voltage for either of them
Also, I'm having an issue with my passenger side tail light, the actual light itself lights up fine, and the lights on my drivers side work perfect, but the little decorative red lights on the outside of the tail light on the passenger side don't work, and if you go to O'Reilly or autozone they can't even get them, so what are they called and how do I get them working again?
