Code P2196 2005 Toyota Prius Description
The P2196 diagnostic trouble code for a 2005 Toyota Prius indicates that the Oxygen Air/Fuel Sensor Signal is stuck rich on Bank 1 Sensor 1. This means that the oxygen sensor located in the exhaust system before the catalytic converter is detecting a consistently rich air/fuel mixture in the exhaust gases. The engine control module (ECM) uses this sensor to monitor the oxygen content in the exhaust and adjust the air/fuel mixture for optimal combustion. When the sensor signal is stuck rich, it means that the engine is running with too much fuel compared to the amount of air, leading to a rich fuel mixture.
