Code P050B 2009 Toyota Camry Description

The Electronic Throttle Control System (ETCS) controls the engine idling speed. The ETCS operates the throttle actuator to open and close the throttle valve and adjusts the intake air amount to achieve the target idling speed. In addition, the Engine Control Module (ECM) retards the ignition timing and the ETCS increases the intake air amount to quickly increase the catalyst temperature at the cold start to reduce emissions. The Diagnostic Trouble Code (DTC) will set when the temperature of the catalyst inlet does not rise to the proper temperature when the engine is started with pre-warming up condition.
