Code P2195 2010 Toyota Corolla Description
The P2195 code for a 2010 Toyota Corolla indicates that the oxygen sensor in Bank 1 Sensor 1 is reporting a lean air/fuel mixture. This means that there is an imbalance in the ratio of air to fuel in the engine's combustion process. The oxygen sensor is responsible for monitoring the oxygen levels in the exhaust gases and sending this information to the engine control module (ECM) for proper fuel delivery. When the sensor detects a lean condition, it means that there is too much oxygen in the exhaust, indicating that the engine is running with a higher air-to-fuel ratio than optimal.
Common Causes of P2195 2010 Toyota Corolla
- Faulty oxygen sensor
- Vacuum leak in the intake system
- Clogged fuel injector
- Malfunctioning mass airflow sensor
- Fuel delivery system issue
