Code P2195 2009 Honda Accord Description
The P2195 code for a 2009 Honda Accord indicates an issue with the Rear Air/Fuel (A/F) Sensor 1 on Bank 1, specifically that the signal is stuck lean. This sensor is responsible for 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 sensor detects a lean condition, it means that there is an excess of oxygen in the exhaust, which can lead to a variety of performance issues.
Common Causes of P2195 2009 Honda Accord
- Faulty rear A/F sensor
- Vacuum leak in the intake system
- Clogged fuel injector
- Malfunctioning fuel pressure regulator
- ECM issue
Symptoms of P2195 2009 Honda Accord
- Rough idling or stalling
- Decreased fuel efficiency
- Hesitation or lack of power during acceleration
- Check Engine Light illuminated
