Code P2195 2008 Toyota Prius Description
The P2195 diagnostic trouble code (DTC) for a 2008 Toyota Prius indicates that the Oxygen Air/Fuel Sensor Signal is stuck lean on Bank 1 Sensor 1. This means that the oxygen sensor located in the exhaust system before the catalytic converter is detecting a consistently lean air/fuel mixture in the exhaust gases. The engine control module (ECM) uses this sensor's data to adjust the air/fuel ratio for optimal combustion. When the sensor signal is stuck lean, it can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
