Component Description
NGEC0462
When the air conditioner is on, the IAC valve-FICD solenoid valve
supplies additional air to adjust to the increased load.
ECM Terminals and Reference Value
NGEC0463
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM’s transistor. Use a ground other than ECM terminals, such as the ground.
