Code P2122 2006 Toyota Camry Description
The P2122 diagnostic trouble code for a 2006 Toyota Camry indicates a problem with the Throttle Pedal Position Sensor/Switch 'D' Circuit Input being too low. This sensor is crucial for the vehicle's Electronic Throttle Control System (ETCS) as it monitors the position of the throttle pedal and communicates this information to the Engine Control Module (ECM). When the sensor detects that the throttle pedal position is too low, it can cause issues with engine performance and overall drivability. If left unaddressed, this issue can lead to reduced fuel efficiency, poor acceleration, and potential stalling of the vehicle.
