Description
In this circuit, the compressor receives a refrigerant compression demand signal from the air conditioning amplifier. Based on this signal, the compressor changes the degree of refrigerant compression.
Hint:
*: Compressor and pulley for 2az-fe, compressor and magnetic clutch for 2gr-fe

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 ...
Throttle actuator control system
Description
The throttle actuator is operated by the ecm, and opens and closes the
throttle valve using gears. The
opening angle of the throttle valve is detected by the throttle position (tp)
sensor, which is mounted on
the throttle body. The tp sensor provides feedback to the ecm in ord ...
