Intake Sensor Test

Intake Sensor:

INTAKE SENSOR
The intake sensor converts temperature of air after it passes through the evaporator into a resistance value which is then input to the auto amplifier.

Intake Sensor:

After disconnecting intake sensor harness connector, measure resistance between terminals 33 and 37 at sensor harness side, using the table below.
