B2631 NISSAN Possible Causes 1 Faulty Sunload Sensor 2 Sunload Sensor harness is open or shorted 3 Sunload Sensor circuit poor electrical connection 4 Faulty Air Condition (A/C) Automatic Amplifier More …
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.
How does the sunload sensor work on a Nissan Maxima?
The sensor converts the sunload into a current value, which is then input into the A/C auto amp. The A/C auto amp. also equips a processing circuit which averages the variations in detected sunload over a period of time.

When to use sunload sensor for circuit diagnosis?
• Sunload sensor may register a malfunction when indoors, at dusk, or at other times when light is insufficient. When performing the diagnosis indoors, use a lamp (60 W or more) that is pointed at the sunload sensor. 1. Turn ignition switch ON. 2. Select “Self Diagnostic Result” mode of “HVAC” using CONSULT-III.
Where are the sunload sensors on the dash?
Sunload Sensors Explained. 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.
