What is the P2196 Error Code?

The P2196 error code is a diagnostic trouble code (DTC) that occurs when the oxygen (O2) sensor on bank 1 detects too much fuel and not enough oxygen in the exhaust gas. This imbalance can affect the performance and fuel efficiency of your vehicle.

Causes of P2196 in Ford Mustang

Several factors can lead to the P2196 error code in your Ford Mustang:

  • Faulty O2 Sensor: The most common cause is a defective oxygen sensor that needs replacement.
  • Fuel Pressure Issues: High fuel pressure can lead to excess fuel in the engine, triggering this error.
  • Leaking Injectors: Fuel injectors that leak can also cause a rich fuel condition.
  • Exhaust Leaks: Leaks in the exhaust system near the O2 sensor can lead to incorrect readings.
  • Engine Misfires: Misfiring can cause unburnt fuel to exit the engine, leading to a rich condition.
