Code P0144 Ford Description
The P0144 diagnostic trouble code for Ford vehicles indicates an issue with the O2 sensor circuit on Bank 1 Sensor 3, specifically detecting high voltage. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring the amount of oxygen in the exhaust gases to help the engine control module adjust the air-fuel mixture for optimal combustion. When the sensor detects high voltage, it suggests that there is an excess of oxygen in the exhaust system, which could lead to a lean air-fuel mixture.
