ON-VEHICLE INSPECTION
1. INSPECT IAC VALVE FOR OPERATING SOUND
Check that there is a clicking sound immediately after stopping
the engine.
If operation is not as specified, check the IAC valve, wiring and
ECM.
2. INSPECT IAC VALVE RESISTANCE
NOTICE:
ºColdº and ºHotº in these sentences express the tempera-
ture of the coils themselves.
ºColdº is from -10°C (14°F) to 50°C (122°F) and ºHotº is
from 50°C (122°F) to 100°C (212°F).
Using an ohmmeter, measure the resistance between the ter-
minals (B1 (or B2) to others).
Resistance:
Cold15 - 25 W
Hot20 - 30 W
If resistance is not as specified, replace the IAC valve.
