I was driving the other day and my CEL came on. Code was for Bank 2 Sensor 2 High voltage. I cleared it out and monitiored it on a 20 minute drive and the voltage stayed around .20-.28. The other 3 sensors read as high as .80.
My question I have is is Bank 2 the Passager or Driver side? I am just replaced the passanger valve cover gasket and just wanna make sure it isn't leaking. It doesn't appear to be from what I can see but that O2 sensor worries me that it may have leaked out of the rear onto the sensor.
O2 Sensor

Re: O2 Sensor
Bank 2 sensor 2 would be the passenger side rear.

Re: O2 Sensor
Thats what I was affraid of. Hopefully the O2 sensor is just bad and my valve cover isn't leaking anymore.

Re: O2 Sensor
I have same code on my '99 and I bought a replacement O2 sensor, but was wondering...
...are their any driveability issues with a bad bank 2 rear O2 sensor?

Re: O2 Sensor
No real drivability issues with the rear o2 sensors. Slight fuel trim modificaction. just depends on what your sensor is reading on how close your ttrims will be.
