"After I installed my Stainless Works header kit, I’ve been stuck with code P0132 (O2 Sensor Circuit High Voltage). I’ve ensured all bolts are tightened, even after several heat cycles. I also installed a new O2 sensor, checked the fuses, and recorded live data.

I am running a BBK cold air intake, and someone suggested I reinstall the stock intake to test it. However, since the O2 sensor is stuck at 1.25V, I don’t see how the intake would be the issue. While driving, my fuel trims stay deep in the negatives (ranging from 0.0 down to -80). I just don’t understand why the voltage is stuck at 1.25V. I also removed the bracket that held the two 02 sensors together, which was held down with a nut, and when I look from up top and down below, I don't see the wires touching or rubbing against the headers.

Did the headers require o2 extensions?

Check to make sure the wires go to the correct cavities in the extensions. Make sure none of the pins backed out of the connector when they were plugged in. Make sure the harness isn't laying on the metal header on the passenger side.
