just ran tech stream
on wifes 07 GS350. Did health check and got a couple codes for A/C. B1421 and B1424. Solar sensors and I did the check inside my garage. Was wondering if I did it again out in the sunlight would that clear them? Anyone notice these codes?

Huh, I had no ideas they did this...
DESCRIPTION
The solar sensor, which is installed on the upper side of the instrument panel, detects sunlight and
controls the air conditioning AUTO mode. The output voltage from the solar sensor varies in accordance
with the amount of sunlight. When the sunlight increases, the output voltage increases. As the sunlight
decreases, the output voltage decreases.
The air conditioning amplifier detects changes in the output voltage from the solar sensor.

I am guessing the thermostat and light sensor give the same feed to the computer. They are 2 different feed but they act the same, the feed for that sensor increases and decrease and the computer need A/D to translate that voltage to digital.

they can't use the light sensor to do temperature, it's completely different. You are reading it wrong.
