Solar Radiation Sensor Inspection

WARNING: This page is about a different car, the 2007 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

Shine a fluorescent light or expose the solar radiation sensor to natural sunlight.
Connect the positive (+) lead to terminal A and the negative (-) lead to terminal B of the solar radiation sensor, and verify that the voltages are as shown in the table.
- If the voltage is not as specified, replace the solar radiation sensor.
