Code P2195 2007 Toyota Highlander Description
The diagnostic trouble code P2195 for a 2007 Toyota Highlander indicates that the Oxygen Air/Fuel Sensor Signal is stuck lean on Bank 1 Sensor 1. This means that the oxygen sensor located before the catalytic converter is detecting a consistently lean air/fuel mixture in the exhaust gases. This can lead to inefficient combustion, reduced engine performance, and increased emissions. The Engine Control Module (ECM) uses the oxygen sensor's readings to adjust the air/fuel mixture for optimal combustion. When the sensor is stuck lean, it can cause drivability issues and potentially damage the catalytic converter over time.
Common Causes of P2195 2007 Toyota Highlander
- Faulty oxygen sensor
- Vacuum leaks in the intake system
- Fuel delivery issues
- Exhaust leaks
- Wiring or connector problems
