Sedona EX V6-3.5L (2002)
Air Flow Meter/Sensor: Testing and Inspection
AFS, IATS
The air flow sensor adopts the feature of maintaining a certain temperature of the heater for sensor to make the hot film element detect the air flow and
send related signal to the ECM. The ECM then determines the fuel amount and ignition timing and check the information to apply the fuel and A/C load
correction.
The IAT is used to detect the temperature of intake air to support the correction of fuel flow and ignition timing, and the compensation of air temperature
for idle control.
