Air/Fuel gauge problems

Ok so I just installed an Air/fuel ratio gauge last night. I decided to wire it to the driver side o2 sensor for signal (the one behind the second cat) and I test drove it last night and the gauge worked perfectly fine. Well this morning I drove to class and right when I left my garage, I got a check engine light . The code is a P0158 as well as P0606 now I looked up the code and its 02 Sensor Circuit High Voltage (Bank 2 Sensor 2). As far as I know (someone correct me if I'm wrong) that's the passenger side sensor. I'm kinda stuck as to what to do about it.

I know that its a narrowband and not a wideband and most of my searching just turned up people saying that the narrowband is crap and the wideband is the best. I am trying to avoid those kind of responses, I just want to solve this problem. Any help would be appreciated.

 

Thats what I was thinking but why would the error be for the passenger side sensor?

 

You A/F gauge is messing up the signal to the computer from the O2 Sensor as previously stated. As you know Narrowband is complete crap. On another note. The point of a A/F gauge is to tell you how your engine is running. Placing it after a device that burns up any excess fuel in the exhaust stream is completely useless information anyways. It gives you absolutely no indication of the A/F that your engine is running. Another thing is that this information is pretty useless and of very little interest unless you are running a boosted application. Your CPU keeps tight reigns on the A/F ratio based on the O2 sensors and knock sensors. no need to keep an eye on it.

 

The 'Bank 2 Sensor 2' unit is one of the two Heated O2 Sensors - the same component you say you wired the A/F Ratio gauge into.

Like PRS 2 TiFJ already noted, I have no idea why you'd want to wire an A/F Ratio gauge into one of the Heated O2 Sensors.

For the locations of the A/F Ratio Sensors (Bank 1 Sensor 1; Bank 2 Sensor 1), see:

 

Thanks for the responses, I wired it to that sensor because it was easier to get to and I didn't think there was a difference between the two.
I hope to get a blower this summer and when I do I will go for the wideband but this was just the gauge that I got with the pod pillar.
I was trying to follow these instructions: http://www.autometer.com/download_instruction/2650-1163-00rA.pdf Is there a wire in the ecm that I could use instead of going directly to the sensor itself?

(Oh and I disconnected the gauge and that got rid of the CEL)
