Help me out

Ive gotten the P0138 and P0152 codes over the month. It says high voltage or something like that. I got both at the beginning of the month but my gas pedal gets sticky sometimes when I stop then go to hit it and sometimes it makes me look like im racing at the light and figured that caused high output to the o2 sensors and cleared it. Well 3 weeks later it showed up again today without the sticky pedal. Whats causing it? Bank 1 sensor was replaced when I replaced knock sensor.

Both of those codes refer to Bank 2. p0152 is Sensor 1 responding with a high voltage; p0138 is Sensor 2 responding with a high voltage.

Both codes refer to a bad harness or bad sensors. I would check the harness connectors for water ingress, or if they're loose. The connectors are all on the B1 valve cover. If there's no water, and they're firmly attached, I'd probably just shotgun them.
