INSPECTION
INSPECT IAC VALVE OPERATION
(a) Connect the positive (+) lead form 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.
If operation is not as specified, replace the IAC valve.

EFI MAIN RELAY
INSPECTION
1. REMOVE EFI MAIN RELAY (Marking: EFI MAIN)
LOCATION: In the engine compartment relay box.
2. INSPECT EFI MAIN RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals 86 and 85.
If there is no continuity, replace the relay.
(b) Check that there is no continuity between terminals 87
and 30.
If there is continuity, replace the relay.
3. INSPECT EFI MAIN RELAY OPERATION
(a) Apply battery voltage across terminals 86 and 85.
(b) Using an ohmmeter, check that there is continuity be-
tween terminals 87 and 30.
If there is no continuity, replace the relay.
4. REINSTALL EFI MAIN RELAY

INSPECTION
1. REMOVE VSV
2. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals.
Resistance: 33 - 39 W at 20°C (68°F)
If there is no continuity, replace the VSV.
3. 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.
4. 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.
5. REINSTALL VSV
