U0606Lost Communication With Throttle/Pedal Position Sensor/Switch A

U0606 is a communication fault where one control module on the vehicle's Controller Area Network (CAN) bus has stopped receiving valid messages from the module responsible for the throttle or pedal position sensor A circuit. The computer that set the code did not detect an electrical failure inside the sensor itself, but rather a loss of the digital data broadcast that describes the pedal or throttle position.
