Code P2240 2011 Toyota Camry Description

The P2240 diagnostic trouble code (DTC) for a 2011 Toyota Camry indicates a problem with the Oxygen A/F (Air-Fuel) Sensor Pumping Current Circuit Open on Bank 2 Sensor 1. This sensor is responsible for measuring the oxygen content in the exhaust gases and sending this data to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. In this case, the circuit for the sensor on Bank 2 Sensor 1 is open, meaning there is an interruption in the electrical connection between the sensor and the ECM.
