Joe more information for ya......


In-Car Temperature Sensor
The A/C-heater programmer monitors the temperature of the air
inside of the vehicle by applying a reference voltage to the in-car
thermistor temperature sensor. A slight vacuum in the A/C-heater
plenum draws passenger compartment air through an aspirator hose to
the in-car temperature sensor.
