Code P0221 2007 Toyota Camry Description

The P0221 diagnostic trouble code (DTC) for a 2007 Toyota Camry indicates a Throttle/Pedal Position Sensor/Switch 'B' Circuit Range/Performance Problem. This code is triggered when the Engine Control Module (ECM) detects that the signal from the throttle position sensor or pedal position sensor 'B' does not fall within the expected range or is not performing as it should. The throttle position sensor (TPS) is responsible for monitoring the position of the throttle valve, while the pedal position sensor detects the position of the accelerator pedal. Both sensors play a crucial role in the engine management system by providing input to the ECM to adjust fuel delivery and ignition timing.
