Code P0136 Ford Description

The P0136 diagnostic trouble code for Ford vehicles indicates a malfunction in the heated oxygen sensor circuit for bank 1 sensor 2. The heated oxygen sensor (HO2S) is responsible for monitoring the oxygen content in the exhaust gases and sending this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. Bank 1 sensor 2 refers to the sensor located downstream of the catalytic converter on the side of the engine where cylinder 1 is located.
