Toyota Repair: 2006 TOYOTA COROLLA CHECK ENGINE LIGHT, air fuel ratio, 2006 toyota corolla

Question
2006 TOYOTA COROLLA CHECK ENGINE LIGHT IS ON THE CODE READS P0171B THEN HE RESET THE LIGHT. THE 2ND TIME THE LIGHT CAME ON THE CODE WAS P0032. HE TOLD ME THAT ONE OF THE BANKS IN THE ENGINE IS RUNNING LEAN. I WAS TOLD SHOULD BE AN O2 SENSOR BUT DONT KNOW WHICH ONE. ANY IDEAS OR DOES THIS SOUND CORRECT?

Answer
The P0032 code is for the air/fuel ratio sensor bank one which is located in the exhaust manifold, you can see it by looking between the engine and the firewall, if the code P171 is fixed then replace this sensor.
