IN-VEHICLE SENSOR
IN-VEHICLE SENSOR
Description
INFOID:0000000009950982
COMPONENT DESCRIPTION
• The in-vehicle sensor (1) is installed to the finisher.
• The in-vehicle sensor converts the interior air temperature of the
passenger room sucked by the aspirator detected with the ther-
mistor into the voltage, and the A/C auto amp. inputs this voltage.
ASPIRATOR
The aspirator (1) generates the vacuum by the air blown from the A/
C unit assembly and draws the air of the passenger room to the in-
vehicle sensor area via the aspirator duct.
INTERIOR AIR TEMPERATURE CORRECTION
• The A/C auto amp. inputs the temperature detected with the in-vehicle sensor as the interior air temperature.
• Perform the correction of the temperature detected with the in-vehicle sensor for each air conditioner control.
Diagnosis Procedure
INFOID:0000000009950983
1.
CHECK IN-VEHICLE SENSOR POWER SUPPLY CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect the in-vehicle sensor connector.
3.
Turn the ignition switch ON.
4.
Check voltage between in-vehicle sensor harness connector and the ground.
