Code B1260 GMC Description

Under normal operation, the solar radiation sensor receives a ground through the circuit. A 5-volt reference voltage is supplied to the solar radiation sensor from the Electronic Automatic Temperature Control (EATC) Module through. The EATC Module monitors the Solar Radiation Sensor. The EATC Module sets the OBDII code when the Solar Radiation Sensor is not to factory specifications.
