Code P0152 2000 Ford F150 Description

The P0152 diagnostic trouble code (DTC) for a 2000 Ford F150 indicates an issue with the O2 sensor circuit high voltage for Bank 2 Sensor 1. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases to help the engine control module (ECM) adjust the air-fuel mixture for optimal combustion. Bank 2 refers to the side of the engine that does not contain the number one cylinder.
