P0140
I keep getting this code P0140.
"P0140 Heated Oxygen Sensor (HO2S) Circuit Insufficient Activity Bank 1 Sensor 2 "
Can anyone tell me if it's the rear/front/left/right O2 sensor.I read that the P0140 and P0160 are rear O2 sensor related...or are these front related?

Bank 1 is driver's side of the engine ....
Sensor 2 is the one behind the cats ....
First thing to check is the wiring to the sensor .... sometimes (especially if you have headers) the wiring insulation is damaged by the heat and the exposed wire can cause the problems you are seeing.
