P0141 O2 Sensor Heater Circuit (Bank 1 Sensor 2) Low
The P0141 code means the heater in the oxygen sensor located after the catalytic converter is not drawing the expected current. The engine keeps running normally, but the catalyst monitor never completes and the vehicle will not pass an emissions inspection. It is a low severity code and you can keep driving.
