EFI MAIN RELAY
INSPECTION
1. REMOVE EFI MAIN RELAY (Marking: EFI)
2. INSPECT EFI MAIN RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals 1 and 2.
If there is no continuity, replace the relay.
(b) Check that there is no continuity between terminals 3 and
5.
If there is continuity, replace the relay.
3. INSPECT EFI MAIN RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is continuity be-
tween terminals 3 and 5.
If there is no continuity, replace the relay.
4. REINSTALL EFI MAIN RELAY

(b) Check that there is continuity between terminals +B and
FC.
If there is no continuity, replace the relay.
(c) Check that there is no continuity between terminals +B
and FP.
If there is continuity, replace the relay.
4. INSPECT CIRCUIT OPENING RELAY OPERATION
(a) Apply battery voltage across terminals STA and E1.
(b) Using an ohmmeter, check that there is continuity be-
tween terminals +B and FP.
If there is no continuity, replace the relay.

VSV FOR EVAPORATIVE
EMISSION (EVAP)
INSPECTION
1. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals.
Resistance: 30 − 34 Ω at 20°C (68°F)
If there is no continuity, replace the VSV.
2. 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.
3. INSPECT VSV OPERATION
(a) Check that air does not flow from pipe E to pipe F.
(b) Apply battery voltage across the terminals.
(c) Check that air flows from pipe E to pipe F.
If operation is not as specified, replace the VSV.
