Blink Code 47
IAC: Short to Ground
IAC = Idle Air Control, part of the EFI system.
The IAC is a non-serviceable item. If it is faulty, it must be replaced.
1-2, 30 ohms
2-3, 30 ohms
1-3, 60 ohms
4-5, 30 ohms
5-6, 30 ohms
4-6, 60 ohms
All other combinations = OPEN
I can't tell by the wiring diagram on my PC which wire would be ground.
Since the fault says Short to Ground, one of the "All other combinations = OPEN" should be closed.
Such as 1-4, 1-5, 1-6 etc.
Make a table on a piece of paper or spreadsheet and map out all combinations. Then test.
If all the pins in the table above read correctly, and all other combinations read open, the Short to Ground is elsewhere.
Let us know what you find.
