Code P0222 2007 Toyota Camry Description

The P0222 code for a 2007 Toyota Camry specifically refers to a fault in the Throttle/Pedal Position Sensor/Switch 'B' Circuit, indicating a low input signal being detected by the Engine Control Module (ECM). This sensor is responsible for monitoring the position of the throttle pedal and sending this information to the ECM, which then adjusts the air-fuel mixture and engine performance accordingly. A low input signal suggests that the sensor is not providing the expected voltage signal, which can lead to a variety of performance issues.
