What does Sunload sensor do?
Sunload sensors monitor the intensity of sunlight and adjust the HVAC control to improve the comfort level of the driver and passengers on sunny days. Sunload sensors are usually located at the top of the dash and are often mounted on a removable plate, speaker grill, or defroster vent.
What does the sunload sensor on a Mazda do?
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. The RCC Module monitors the Solar Radiation Sensor. The RCC Module sets the OBDII code when the Solar Radiation Sensor is not to factory specifications.
Why is my sun load sensor not working?
The sun load sensor contains a photo diode that’s sensitive to sun light. Resistance in the sensor increases as sun load increases. If the sensor is covered with a dash cover or a window sticker, the control module will receive inaccurate information and make incorrect adjustments.
Where is the sun load sensor on the dash?
Sun Load Sensor Test: It’s on the dash usually close to the headlight sensor. As sunlight increases, the sensor’s signal voltage decreases. View voltage readings in a capable scan tool datastream. Park the vehicle in bright sunlight. With ignition on KOEO check voltage readings against specifications.
What does bright sunlight do to a sunload sensor?
Bright sunlight conditions can result in the fan speed increasing, and blend doors opening to improve cooling. NOTE: Sunload sensors do not respond to fluorescent light, which is read as darkness.
