Code P2195 2007 Toyota Prius Description
The P2195 code for a 2007 Toyota Prius indicates that the Oxygen Air/Fuel Sensor Signal is stuck lean on Bank 1 Sensor 1. This means that the sensor responsible for monitoring the air/fuel mixture in the engine is reporting a lean condition consistently. The oxygen sensor plays a crucial role in the engine's performance by providing feedback to the engine control module (ECM) to adjust the air/fuel mixture for optimal combustion. A lean air/fuel mixture can lead to poor engine performance, reduced fuel efficiency, and increased emissions.
