INSPECT INTAKE AIR CONTROL VALVE ASSY NO. 2




a. Apply 26.7 kPa (200 mmHg, 7.9 in.Hg) of vacuum to the actuator. Check if the actuator rod pulls the lever and causes the valve to rotate open, as shown in the illustration.
b. Apply the vacuum for 1 minute. Check that the actuator rod does not return.

If the result is not as specified, replace the IAC valve assy No. 2.

b. Apply the vacuum for 1 minute. The actuator should continue to be keeping the valve open.

If the result is not as specified, replace the IAC valve assy No. 3.
