How to fix P0031 Code: HO2S Heater Control Circuit Low (Bank 1 Sensor 1)
An oxygen sensor monitors how much oxygen was burned off during combustion. The computer uses the information to adjust the air/fuel ratio mixture.
Oxygen sensors have heating elements that preheats the sensor during cold start conditions. This speeds up the process of getting the oxygen sensor up to operating temperature.
Common causes of a P0031 code include an open heater power (usually 12v) circuit, a damaged connector, and a defective oxygen sensor heater element.
