IDLE AIR CONTROL (IAC) VALVE
ON−VEHICLE INSPECTION
1. INSPECT IAC VALVE OPERATION
(a) Initial conditions:
Engine at normal operating temperature
Idle speed set correctly
Transmission in neutral range
(b) Using SST, connect terminals TE1 and E1 of the
DLC1.
SST 09843−18020
(c) After engine rpm are kept at 1,000 − 1,500 rpm for 5 se-
conds, check that they return to idle speed.
If the rpm operation is not as specified, check the IAC valve, wir-
ing and ECU.
(d) Remove SST.
SST 09843−18020
2. INSPECT IAC VALVE RESISTANCE
NOTICE:
”Cold” and ”Hot” in the following sentences express the
temperature 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).
(a) Disconnect the IAC valve connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal +B and other terminals (RSC, RSO).
Resistance:
Cold: 21.5 − 28.5Ω
Hot: 17.0 − 24.5Ω
If resistance is not as specified, replace the IAC valve.
(c) Reconnect the IAC valve connector.
