WITH INTELLIGENT AIR CONDITIONER SYSTEM : DescriptionINFOID:0000000003884752
COMPONENT DESCRIPTION
Gas Sensor
The gas sensor (1) is attached on the bumper upper retainer. It
detects smell of exhaust gas and converts it into a duty ratio which is
then input into the A/C auto amp.
Gas Sensor Circuit
SMELL OF EXHAUST GAS INPUT PROCESS
Gas sensor detects ambient atmospheric CO and NO2, and converts them to values of resistance. The values
are converted to signals with the gas sensor internal circuit, then auto amp. inputs the signals.
Gas sensor has a construction that detects CO and NO
2 by gas sensor element from the air intake of the case
through a filter (waterproof sheet). It sends output signals to auto amp. in response to a resistance value con-
version by gas sensor elements. Output signals prevent a smell of exhaust gas from getting into vehicle by
performing corrections according to various driving conditions.

B2630, B2631 SUNLOAD SENSOR
B2630, B2631 SUNLOAD SENSOR
DescriptionINFOID:0000000003884756
COMPONENT DESCRIPTION
Sunload Sensor
 The sunload sensor (1) is located on the driver’s side speaker
grille.
 It detects sunload entering through windshield by means of a
photo diode. The sensor converts the sunload into a current value
which is then input into the A/C auto amp.
Sunload Sensor Circuit
SUNLOAD INPUT PROCESS
The A/C auto amp. also equips a processing circuit which averages the variations in detected sunload over a
period of time. This prevents drastic swings in the air temperature control system operation due to small or
quick variations in detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor varies whenever the trees obstruct the sunlight. The processing circuit aver-
ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the air temperature control system operation. On the
other hand, shortly after entering a long tunnel, the system recognizes the change in sunload, and the system
reacts accordingly.
