Auxiliary Air Control (AAC) Valve Test (Except Maxima VG30E)
To test AAC valve, check resistance across AAC valve connector terminals. If resistance is not approximately 10 ohms, replace AAC valve. Ensure plunger does not stick and plunger spring is not broken.
NOTE:
On Maxima VG30E, AAC valve is a stepper motor with multiple sets of windings.
