Code P0222 2010 Toyota Camry Description

The P0222 diagnostic trouble code (DTC) in a 2010 Toyota Camry indicates a problem with the Throttle/Pedal Position Sensor/Switch 'B' Circuit, specifically a low input signal. This sensor is crucial for the proper functioning of the vehicle's electronic throttle control system. The throttle position sensor (TPS) is responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). The ECM uses this data to determine the appropriate air-fuel mixture for combustion in the engine.
