ON VEHICLE SERVICE:
ISC Solenoid Valve Resistance Check
1.
With the ignition switch OFF, disconnect the IAC solenoid valve coupler.
2.
Connect an ohmmeter to each IAC solenoid valve terminal and measure resistance. Resistance should be 5.4-6.6 ohms at 20°C (68°F). If resistance
is out of specification, replace the IAC valve.
REMOVAL:
1.
Disconnect the negative battery terminal.
2.
Disconnect the IAC solenoid valve coupler.
3.
Remove the IAC solenoid valve wire harness terminals from the coupler after unlocking the terminal lock of coupler.
4.
Remove the IAC solenoid valve from the throttle body.
CAUTION: The IAC solenoid valve is an electrical component and must NOT be soaked in any liquid solvent or cleaner. Otherwise damage may
occur.
ISC Solenoid Valve Operation
5.
Connect battery voltage to the IAC solenoid valve terminals momentarily (within 1 second) and disconnect it immediately. While doing so, check
the valve for operation. When another check is necessary, wait for longer than 10 seconds before rechecking. Refer to DIAGNOSIS AND
TESTING PROCEDURES/DIAGNOSTIC CHARTS/C CHARTS/CHART C2.
INSTALLATION:
1.
Install the IAC solenoid valve into the throttle body.
2.
Install the IAC solenoid valve wire terminals into the coupler and install the terminal lock.
3.
