Replaced my post cat drivers side O2 sensor tonight because I was getting zero voltage and a p0430 code. This is bank 2 sensor 1.
But I'm still reading zero voltage!! How could I still be getting zero voltage?? I checked the connections and they are firm. Checked every single fuse in car.
After my recent accident, the center console lights don't illuminate. My nav door doesn't close too. Could these all be related?? The connector for the O2 sensor is right next to the console, so maybe there is a loose connection or plug or perhaps a stray ground?? I do have wires all over the place in under the shifter bezel from aftermarket stuff..
What do you all think? This is driving me freakin nuts. If you have any ideas please let me know!!!
Thanks!!
Yeah, I actually did install back up sensors as well as front sensors. The rear sensors are powered by the back up lights in the trunk, but in the front I piggybacked onto one of the fuses. I will check after work. How could the O2 sensor be related???
Correction: I wired the parking sensors to the fuse box in the cabin kick panel on the drivers side. This morning I noticed there was some abrasion near the shifter where you stick something in to release the wheel lock. That's just inches away from the connector for the 02 sensor on the drivers side that isn't supplying power... Looks like I will need to get a test light/voltmeter and check connections when I open the shifter bezel??

I just wanted to find out if you were in that fuse box for the sensor power. You said it was inside the drivers side cabin.
Also, the fuse I listed in the previous post supplies power to bank 1 & 2, sensor 2. Or both downstream O2 sensors.

Holy cow I am going to check as soon as I can?! That would be awsome if that was the problem, ie just a fuse. But I'm sure I already check that one. Hopefully I am wrong

Hey Buddy, I'm getting zero voltage from bank 2 sensor 1. Isn't that the post cat sensor on the drivers side?? What fuse governs this sensor?? I'm not sure if I understand your post sorry for the confusion :-)
I must have made a mistake...
Okay just to be clear,
Bank 1, drivers side, left
Bank 2, passengers side, right
Sensor 1, before the cat, closest to the engine
Sensor 2, after the cat, closest to the muffler.

This would be the O2 sensor on the passenger side, right side and sensor 1 is before the cat, closest to the engine.
Omg are you kidding me! I thought Bank 2 sensor 1 was the post cat sensor on driver side!!! So this is the one one the PASSENGER side pre-cat?! Correct?
Wow I feel very stupid! Looks like I just need to check/swap the pre-cat sensor on passenger side just like you advised!! This would make sense since the douche mechanic probably had to unhook this at some point to do the engine sway and probably broke or left unhooked!

New oxygen sensor reading 0 voltages
