Code P0221 2010 Toyota Camry Description

The P0221 diagnostic trouble code (DTC) for a 2010 Toyota Camry indicates a Throttle/Pedal Position Sensor/Switch 'B' Circuit Range/Performance Problem. This code is typically triggered when the Engine Control Module (ECM) detects that the voltage signal from the throttle position sensor or pedal position sensor is outside the expected range or performance parameters. The throttle position sensor (TPS) and pedal position sensor (PPS) play crucial roles in the proper operation of the vehicle's engine management system. The TPS informs the ECM about the position of the throttle plate, while the PPS provides input on the position of the accelerator pedal.
