Code P2196 2006 Ford Fusion Description
The P2196 code for a 2006 Ford Fusion indicates that the oxygen sensor signal for Bank 1 Sensor 1 is biased or stuck rich. This means that the oxygen sensor is detecting a consistently high level of fuel in the exhaust gases, indicating a rich air-fuel mixture. The oxygen sensor is a crucial component of the vehicle's emissions system, as it measures the amount of oxygen in the exhaust gases and sends this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
Common Causes of P2196 2006 Ford Fusion
- Faulty oxygen sensor
- Vacuum leak in the intake system
- Malfunctioning fuel injectors
- Issues with the engine's air intake system
