INSPECTION
INSPECT IAC VALVE OPERATION
(a) Connect the positive (+) lead from the battery to terminal
+B and negative (−) lead to terminal RSC, and check that
the valve is closed.
(b) Connect the positive (+) lead from the battery to terminal
+B and negative (−) lead to terminal RSO, and check that
the valve is open.

INSPECTION
1. 4WD:
REMOVE BATTERY
2. REMOVE VSV
3. INSPECT VSV
4. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals.
Resistance: At 20°C (68°F): 33 − 39 Ω
If there is no continuity, replace the VSV.
5. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between
each terminal and the body.
If there is continuity, replace the VSV.
6. INSPECT VSV OPERATION
(a) Check that air flows from ports E to G.
(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from port E to the filter.
If operation is not as specified, replace the VSV.
7. REINSTALL VSV

2. REMOVE VSV
3. INSPECT VSV
4. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals.
Resistance: At 20°C (68°F): 30 −34 Ω
If there is no continuity, replace the VSV.
5. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between
each terminal and the body.
If there is continuity, replace the VSV.
6. INSPECT VSV OPERATION
(a) Check that air does not flow from ports E to F.
NOTICE:
Never apply more than 60 kPa (0.61 kgf/cm
2, 8.7 psi) of
pressure compressed air to the VSV.
(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from ports E to F.
If operation is not as specified, replace the VSV.
