Code P0151 2012 Ford Mustang Description
The P0151 diagnostic trouble code (DTC) for a 2012 Ford Mustang indicates an issue with the O2 sensor circuit low voltage in Bank 2 Sensor 1. The O2 sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel ratio for optimal combustion. In this case, the low voltage reading from Bank 2 Sensor 1 suggests that there may be a problem with the sensor itself, the wiring, or the ECM.
