Code P22AE Description

The P22AE diagnostic trouble code indicates an issue with the O2 sensor located in Bank 1 Sensor 2 of the vehicle's exhaust system. The O2 sensor plays a crucial role in monitoring the oxygen content in the exhaust gases to help the engine control module (ECM) adjust the air-fuel mixture for optimal combustion. When the signal circuit of this sensor is open, it means that there is a break or interruption in the electrical connection between the sensor and the ECM.
