Code P2195 BMW Description
The P2195 code for BMW vehicles indicates that the O2 sensor signal is stuck lean on Bank 1 Sensor 1. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the O2 sensor signal is stuck lean, it means that the sensor is detecting an abnormally low level of oxygen in the exhaust gases on Bank 1, which can lead to a lean air-fuel mixture.
Common Causes of P2195 BMW
- Malfunctioning O2 sensor
- Vacuum leak
- Fuel delivery problem
- Clogged fuel injector
- Exhaust system leak
Symptoms of P2195 BMW
- Decreased fuel efficiency
