02 grand p0155 error

The error code displayed is p0155. the mopar shop manual says "2/1 O2 sensor heater failure" and then under brief description of DTC it says "oxygen sensor heater element malfunction" I am going to replace one of the O2 sensors but which one upstream or down stream? In reading the manual it would seem like the downstream, but i defer to the experts!
