Turn ignition switch on.
Sun sensor location.
Sun sensors are usually classified into three types.
The sun tracking sensors were experimented in operative conditions with direct exposition to the sun.
Field tests of the sun finder sensors.
Sun presence sensor which provides a constant output signal.
Sunload sensor may register a malfunction when indoors at dusk or at other times when light is insufficient.
1 check sunload sensor power supply.
When performing the diagnosis indoors light the sunload sensor with a lamp 60w or more.
It s on the dash usually close to the headlight sensor.
Genuine subaru part 73730sa001 73730sa000.
As the sun load increases the voltage decreases.
As sunlight increases the sensor s signal voltage decreases.
Sun load temperature sensor.
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.
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.
The sun sensor is designed for missions with demanding lifetime radiation thermal and mechanical requirements and can be used in leo meo geo and beyond.
Disconnect sunload sensor connector.
Analog sensor whose output signal is a continuous function of sun angle.
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.
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.
In vehicle sensor component description in vehicle sensor the in vehicle sensor 1 is located on instrument lower panel lh.
Sun load sensor test.
These degrade over time sitting in the direct sun all the time.
When checking sunload sensor select a place where sun shines directly on it.
The sun load sensor is what controls the automatic headlights in the ford crownvictoria mercury grand marquis and many other ford products.
