0158 Code (O2 Sensor Circuit High Voltage) Bank 2 Sensor 2

Viperholics,

I keep throwing this code about every 100 miles. Light stays on until I reset it. Stock headers/new OEM cats/Corsa Exhaust. Is the rear passenger O2 sensor tripping this error code? If so, I may just try to replace them (I have an extra set). Although, they are from a 2001 GTS vs. my 1998 GTS. They are front sensors as well, which I hope are the same as the rears.

Are all 4 O2 sensors the same, and do they vary from 1998-2001? If memory serves, I recall reading that these are all the same.

Thanks.

All the rear sensor does is indicate that the cat is working. I would have someone look at it with a scan tool. You can tell quickly if the sensor is working.
