Idle Speed/Throttle Actuator - Electronic: Testing and Inspection
BAC VALVE
Bypass Air Control Valve Removal
1. Remove the BAC valve screws and remove the BAC valve from the throttle body.
Bypass Air Control Valve
2. Blow air through the valve from port "A" and check that air comes out of port "B" when the BAC valve is cold.
3. Place the BAC valve into hot water (more than 80~C [176~F]) for one minute.
4. Blow air through the valve from port "A" and check that no air comes out of port "B".
5. If not correct, replace the BAC valve.
6. Disconnect the solenoid valve (ISC) connector.
Measuring Idle Speed Control Valve Resistance
7. Connect an ohmmeter to the terminals of the solenoid valve.
8. Check the resistance. It should be 7.7-9.3 Ohms (at 23~C [73~F]).
9. If not as specified, replace the BAC valve.
10. Clean the mating surfaces of the BAC valve and throttle body.
11. Using a new gasket and "O"-ring, install the BAC valve onto the throttle body, tightening the screws to 2.5-3.4 Nm (25-35 cm-kg; 22-30 in-lb).
