What is the P2196 Error Code?
The P2196 error code is an OBD-II (On-Board Diagnostics) trouble code that signifies "O2 Sensor Signal Stuck Rich (Bank 1 Sensor 1)." This code is triggered when the oxygen sensor on bank 1 detects that the fuel mixture is too rich, meaning there is too much fuel and not enough air.

Several issues can lead to the P2196 error code in your Ford Focus:
- Faulty Oxygen Sensor: The sensor itself might be defective.
- Fuel Pressure Issues: Too high fuel pressure can cause a rich mixture.
- Leaking Fuel Injectors: Leaks can lead to excess fuel in the combustion chamber.
- Intake Manifold Leaks: Air leaks can disrupt the air-fuel balance.
- Exhaust Leaks: These can affect the oxygen sensor readings.
