Code P2195 2004 Toyota Highlander Description
The P2195 diagnostic trouble code (DTC) for a 2004 Toyota Highlander indicates that the Oxygen Air/Fuel Sensor Signal is stuck lean on Bank 1 Sensor 1. This means that the air/fuel mixture in the engine is too lean, indicating that there is an imbalance in the ratio of air to fuel being delivered to the engine. The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gases, which helps the engine control module (ECM) adjust the air/fuel mixture for optimal combustion. When the sensor signal is stuck lean, it means that the ECM is receiving a consistently low voltage signal from the oxygen sensor, indicating a lean condition.
