Inspection procedure
Hint: if different dtcs related to different systems that have terminal e2 as the ground terminal are output simultaneously, terminal e2 may be open. If dtc p0441 (purge flow), p0446 (vsv for ccv), p0451, p0452 or p0453 (evaporative pressure sensor) is output with dtc p0442 or p0456, ...

Circuit description
The intake air temperature (iat) sensor, mounted on the mass air flow (maf) sensor, monitors the intake air temperature. The iat sensor has a thermistor that varies its resistance depending on the temperature of the intake air. When the air temperature is low, the resistance in the thermisto ...
