Which O2 sensor is bad? (p0132 error code)

Check Engine light is on and im getting this code:

P0132 (M)
O2 Sensor Circuit High Voltage (Bank 1 Sensor 1)

Which O2 sensor is this exactly? My jeep has 4 sensors.

Thanks

2001 Jeep 4.0 by the way

EDIT: One more thing, if i clear the code it will only come back after the engine has been running for 2-3 minutes or so. I thought this was odd.

It probably has to do with it having two converters so you know which one bad out of the 4 is bad

it says there could be a short wiring.

your problem should be related to one of pre o2 sensors. you may try to disconnect one of pre p2 sensors. then you can check codes. if no signal from same sensor you found it.
