P0137 with secondary o2 disabled?

The error code I got was p0137 and it came back. "O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)

This is with my secondary o2 sensor disabled and a wideband in its place. Any ideas? I want this gone before I hit the track.

This happened after I had my Kidd Racing Header installed, so I know its not life or death, but I want to be able to rely on my CEL again and I can't do that as long as it's throwing this at me.

Anyone know what to do? I need to get it fixed asap so I can go get my tune.

With a MAP or AFM calibration? What is wired into the secondary o2 pin in the place of the secondary o2?

It's map.

I have a innovate wideband in the secondary o2 bung but it is not wired to anything on the ECU. Is that the issue?

I use it as part of my nitrous setup and it has a lean shut off switch.

Can you post the calibration and a datalog?
