B1259 Lincoln Code - Solar Radiation Sensor Circuit Open
Quick Answer
Sunload Sensor (Solar Radiation Sensor) contains a photovoltaic (sunlight sensitive) diode, which measures sunlight entering vehicle and inputs signal to the Remote Climate Control (RCC) module. Common causes include Faulty Sunload Sensor (Solar Radiation Sensor), Sunload Sensor harness is open or shorted, Sunload Sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
