Code P1150 2000 Ford F150 Description

The P1150 diagnostic trouble code (DTC) for a 2000 Ford F150 indicates a lack of upstream heated oxygen sensor switch adaptive fuel limit on bank 2. This means that the oxygen sensor located before the catalytic converter on the side of the engine with cylinder 2 is not functioning properly. The upstream oxygen sensor is responsible for measuring 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.
