IDLE AIR CONTROL VALVE (IAC VALVE)
REMOVAL
1) Remove throttle body from intake manifold referring to
“Throttle Body Removal” section.
2) Remove IAC valve from throttle body.
INSPECTION
1) Connect each connector to IAC valve (1), TP sensor and IAT
sensor.
2) Check that rotary valve (2) of lAC valve opens and closes
once and then stops in about 60 ms as soon as ignition
switch is turned ON.
INSTALLATION
1) Install new gasket (2) to IAC valve (1).
2) Install IAC valve (1) to throttle body (3).
Tighten IAC valve screws to specified torque.
Tightening torque
IAC valve screw (a) : 3.5 N·m (0.35 kg-m, 2.5 lb-ft)
3) Install throttle body to intake manifold referring to “Throttle
Body Installation” section.
NOTE:
This check should be performed by two people, one
person turns on ignition switch while the other checks
valve operation.
As valve operation is momentary, it may be over-
looked. To prevent this, perform this operation check 3
times or more continuously.
If rotary valve of lAC valve does not operate at all,
check wire harness for open and short. If wire harness
is in good condition, replace lAC valve and recheck.
