P0151 - Heated Oxygen Sensor (HO2S) 

Circuit Low Voltage Bank 2 Sensor 1

P0151 Meaning 

The front warmed oxygen sensor (or O2 sensor 1) is set into the ventilation system. It identifies the measure of oxygen in the fumes gas contrasted with the external air. The warmed oxygen sensor 1 has a shut end tube made of fired zirconia. The zirconia produces voltage from roughly 1V in more extravagant conditions to 0V in less fatty conditions. The warmed oxygen sensor 1 sign is shipped off the Engine Control Module (ECM). The ECM changes the infusion beat term to accomplish the best air-fuel proportion. The best air-fuel proportion happens close to the extreme change from 1V to 0V.
