Q: What does code P0062 mean?

HO2S Heater Control Circuit (Bank 2 Sensor 3). P0062 indicates that the powertrain control module has detected a fault in the heater control circuit for the downstream oxygen sensor on bank 2, which is the side of the engine that does not contain cylinder number one. The heater element inside the sensor is not drawing the current the computer expects when it commands the heater on, so the sensor may not reach operating temperature quickly enough to provide accurate exhaust readings.
