Code P2241 2007 Toyota Camry Description

The P2241 diagnostic trouble code (DTC) on a 2007 Toyota Camry indicates an issue with the Oxygen A/F Sensor Pumping Current Circuit Low on Bank 2 Sensor 1. This sensor plays a crucial role in monitoring the air-fuel mixture in the exhaust gases before they enter the catalytic converter. It measures the oxygen content in the exhaust and sends this data to the engine control module (ECM) to adjust the fuel-air ratio for optimal combustion.
