I'm getting error code P0152, which indicates O2 sensor: "high voltage, bank 2, sensor 1", but there are several O2 sensors on the vehicle. Which sensor (location) is this referring to, and what is causing the error code to register??? Any help / advice would be appreciated. Thanks!

 

bank 2 is passenger side, sensor 1 is the closest to the engine..and im guessing its a bad sensor.

 

had the same problem. i cant remeber if it was p0152 or p0155. it might have been the 55.... actually no, it was the one before the cat....the upstream...changed that and problems went bye bye. dont forget to reset your computer after installing it.
