Code p0031 and P0037

Test all the fuses in the car using a test light with the key on.

P0031= Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 1
P0037= Oxygen Sensor Heater Control Circuit Low Bank 1 Sensor 2

Check the fuses and check the wiring harness that leads to the sensors. These codes can be caused by power failure to the heater circuit or an open circuit to ground.
Both of those share the same ground wire and are spliced partway up the harness before they reach connector C111. Check for continuity between the grounds of the sensors and the chassis. No ground = broken wire or bad connector.

Got the Versa figured out yet?

Change both sensor but light still on, use a small scanner to erase codes but still coming back, can i damage something by driving it like that?

Did you test the fuses as I suggested in the first response?
You got 2 responses and neither of them suggested replacing any sensors.

I check the ones close to the battery, all fine Where are connector C111 located? ?? can i drive the car on freeway? need to go out of town like 500 ml round trip

C111 is in the harness coming from the O2 sensors under the vehicle. Not near the battery. The grounds both break out and are attached at ground point G100 which is on the transmission.

check the grounds, fuses, everything's fine, including disconnecting the ground from the battery what else?

Hello,

It sounds like its time to check some wiring, here is a wiring diagram and a guide so you can do some testing.
