there is only ONE solar sensor in the ltd Tundra, located on the driver's side, at the windshield. there is no solar sensor (aka light sensor) on the pass side. perhabs there may be one in the sequoia. the toyota documents are common for both models in that regard.

the sole function of the solar sensor is to info the climate control that there is a sunny day ---> that means that the solar rays warm up the skin and the uper body will feel somewhat hotter that the rest of the body ---> therefore the [earlier mentioned] "air bypass damper" will open up and the air blowing from the upper vents will be a little bit colder than the set temp. all of that happens only in auto function mode! if you manualy set the temp and blower, the solar sensor feedback is DISREGARDED.

the solar sensor provides the a/c amp module with the output voltage of 0.8 to 4.8 Volts depending on how sunny it is. anything below 0.8 volt is considered by a/c amp module as dark/no sun condition.
