wide band oxygen sensore, is this working?
I bought an innovate wide band oxygen sensor (model 3795) a while back, and it didn't appear to be working properly. I recently replaced the actual oxygen sensor part, which is a bosch brand and plugs into the innovate harness, thinking it was damaged during installation.
It reads (from memmory) 22.4 while the car is running, and drops to 7.5 when the truck is off. It was my impression that this should be changing as I rev the engine, but it basically pops on to 22.4 when started and back to 7.5 when turned off. I've had this mounted deeper into the exhaust pipe, thinking it wasn't getting enough air flow, but no change. Is this working properly? Any thoughts? Thanks.

That's interesting voltage. I need to look this up to find out what is proper in all scenarios.
I use a bluetooth obdII adapter and Torque Pro to monitor my truck and the O2 sensors jump all over the place on voltage. Usually around 3-7 volts all the time while driving. I need to pay more attention to that number again and find the specs on those factory style sensors.
So I wouldn't think a wide band sensor would work with a stock computer. Wouldn't think it would be able to read it properly to take advantage of its readings. Am I wrong about that?

I have an android radio in the truck with torque, I'm pretty sure it is pro. I also have a bluetooth obd reader, but I think the tuner needs a wideband reading which is why I bought this expensive thing (twice).

The factory sensor should read between 0 and 1 volt. It bounces around a lot as the PCM is constantly adjusting mixture ratio.

Think I would try and get it up closer to the collectors on the headers. Most any exhaust shop should be able to do you up. (well, if you were in the states anyway.....) Get the sensor as far into the center of the exhaust stream as you can. (that's where the most flow is.)
Wide band should report mixture ratio, not voltage.... 22.something is incredibly lean, and HAS to be wrong.
