The backup lights may also function through the Transmission Range Sensor (TRS) if it is an external component. The code is telling you that the computer has recognized a failure in the TRS sensor. The sensor is either sending an erroneous or no signal at all to the computer identifying the gear position. The computer receives signals from the vehicle speed sensor as well as the TRS.
