P2237 Check engine light

Alright so I seem to throw this code every other week or so, its random. I'll clear it then it'll come back after a week.

My hand held tuner gives me the description but.

I don't know what "o2 sensor possitive current control ckt open" means

any ideas?

I'd check the wiring to bank 1's O2 sensor. If that checks out OK, it is probably the sensor itself.

Right (passenger) side is bank one, if I recall correctly.
