Both o2 Sensors getting NO Voltage?!?!?!

Post by A Psycho Martyr »

I had my uncle take the Vibe into his work (Toyota Dealership) and run the computer to see why I was getting all these codes thrown and such a horrible idle.He brought the Vibe back to me and said that NEITHER o2 sensor is showing anything. Neither is getting voltage, so the MAF sensor is reading high, causing me to run lean. He tried different MAF sensor, didn't fix it. He tried a new o2 sensor, still nothing.He suggests letting a friend with a Vibe who's computer matches the numbers on mine swap and see if that fixes it. Then I'll know if my computer is bad. If that's not it, then we have to search the vehicle for a shorted out wire somewhere I'm sad guys

Each car gets their own issues every now and again. This can be fixed and you'll be back on the road in no time! Sure it depresses me that my rear bumper is horribly gauged and the paint is peeling away, but I know that it is something simple that can, and will, be fixed in a matter of time. If it is a wire, than that should be real easy to fix. But hey, we're all sad to see our cars down and out. I hope all turns out well for you!

You have it fixed yet? There seem to be alot of connections between the power source and the O2 sensors.

Not fixed yet. Haven't looked over anything either. When I get done with today's classes, my bro is coming to detail his T-A and help me with the Vibe. We're gonna look over everything as best we can. If I find anything I'll update
