NOTICE:
"Cold" and "Hot" in these sentences express the tempera-
ture of the coils themselves. "Cold" is from –10°C (14°F) to
50°C (122°F) and "Hot" is from 50°C (122°F) to 100°C
(212°F).

INSPECT IAC VALVE OPERATION
Initial conditions:
D
Engine at normal operating temperature
D
Idle speed set correctly
D
Transmission in neutral position
Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843–18020
After the engine speed is kept at 900 – 1,300 rpm for 5 se-
conds, check that it returns to idle speed.
Remove the SST from the DLC1.
SST 09843–18020
INSPECT IAC VALVE RESISTANCE
Disconnect the IAC valve connector.
Using an ohmmeter, measure the resistance between ter-
minal +B and other terminals (ISCC, ISCO).
Resistance:
Cold
Hot
Reconnect the IAC valve connector.
