Toyota RAV4 Service Manual: Evaporator temperatur sensor
Removal
- Remove air conditioning unit
- Remove the air conditioning radiator (see page ac- 185).
- Remove evaporator temperature sensor (see page ac-193)
Inspection
- Inspect evaporator temperature sensor
- Measure the resistance of the sensor.
Standard resistance 
Notice:
- Even slightly touching the sensor may change the resistance value. Be sure to hold the connector of the sensor.
- When measuring, the sensor temperature must be almost the same as the ambient temperature.
Hint:
As the temperature increases, the resistance decreases (see the graph).
If the result is not as specified, replace the sensor.
Installation
- Install evaporator temperature sensor (see page ac-193)
- Install air conditioning unit
- Install the air conditioning unit (see page ac-197).

Intake air temperature circuit malfunction
Description
The intake air temperature (iat) sensor, mounted on the mass air flow (maf)
meter, monitors the iat.
The iat sensor has a built-in thermistor with a resistance that varies according
to the temperature of the
intake air. When the iat is low, the resistance of the thermist ...
