Sun Sensor Location

1 check sunload sensor power supply.

Sun sensor location. Turn ignition switch on. It s on the dash usually close to the headlight sensor. Analog sensor whose output signal is a continuous function of sun angle. Disconnect sunload sensor connector.

Genuine subaru part 73730sa001 73730sa000. Field tests of the sun finder sensors. As the sun load increases the voltage decreases. As sunlight increases the sensor s signal voltage decreases.

View voltage readings in a capable scan tool datastream. A sun sensor is a device that senses the direction to the sun to measure the position of the sun or other light sources with respect to the sensor position. The bison64 et is a fine sun sensor for high reliable satellites applications and qualified within esa development activities. Sun sensors are usually classified into three types.

Most sunload sensors are the photodiode type which provides increased resistance as the light intensity increases so the signal from the sensor drops as the sun shines brighter. In vehicle sensor component description in vehicle sensor the in vehicle sensor 1 is located on instrument lower panel lh. Sunload sensor may register a malfunction when indoors at dusk or at other times when light is insufficient. However the main advantage of pinhole sensor is to work on two axes while the slit sensor is a sun pointing system working only in one direction.

Sun load temperature sensor. The sun tracking sensors were experimented in operative conditions with direct exposition to the sun. When performing the diagnosis indoors light the sunload sensor with a lamp 60w or more. The operating range is between 0 and 5 volts.

When checking sunload sensor select a place where sun shines directly on it. These degrade over time sitting in the direct sun all the time. When they fail when not if the automatic headlights stay on all the time putting more strain on a fragile lcm lighting control module. Sun load sensor test.

If the sun load sensor fails a fault code sets and the program enters a default value and tries to achieve the desired temperature setting.
