Temperature sensors
1) Solar sensor
2) Interior air temperature sensor
The automatic climate control system
employs several sensors. These sensors
are delicate. If they are treated incorrectly and become damaged, the system may
not be able to control the interior tempera-
ture correctly. To avoid damaging the
sensors, observe the following precau-tions: –
Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors.
The sensors are located as follows:– Solar sensor: beside windshield
defroster grille– Interior air temperature sensor: on the
side of the driver-side part of the center panel – Outside temperature sensor: behind
front grille. Climate control
