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 ...

Check power steering ecu
Hint:
Measurements cannot be performed on the c connector
side of the power steering ecu.
Measure the voltage and resistance of the
connectors.
If the result is not as specified, the ecu may have a
