INTAKE SENSOR

INTAKE SENSOR

Description

INFOID:0000000000959964

Intake Sensor
The intake sensor (1) is located on the heater & cooling unit assem-
bly. It converts temperature of air after it passes through the evapo-
rator (2) into a resistance value which is then input to the unified
meter and A/C amp.
