Code P2195 2012 Toyota Corolla Description
The P2195 code in a 2012 Toyota Corolla indicates an issue with the Oxygen Air/Fuel Sensor Signal being stuck lean on Bank 1 Sensor 1. This means that the oxygen sensor in the exhaust system is detecting a lean air/fuel mixture in the engine's cylinders. The air/fuel mixture in an engine needs to be at a specific ratio for optimal combustion and performance. When the mixture is too lean, there is an excess of air in relation to fuel, which can cause issues with engine performance, fuel efficiency, and emissions.
