P0061

HO2S Heater Resistance (Bank 2, Sensor 3)

DTC P0061, sometimes indicated as P006100 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing ho2s heater resistance (bank 2, sensor 3).

The purpose of the oxygen sensor heater is to keep the sensor's element hot so that it can quickly respond to changes in the air/fuel ratio. The DTC P0061 is set when the heater resistance is out of specification. This may be caused by a faulty heater, a wiring problem, or a bad sensor.
