REMOVE EFI MAIN RELAY (Marking:EFI)

3.

INSPECT EFI MAIN RELAY

(a)

Inspect the relay continuity.
(1)

Using an ohmmeter, check that there is continuity
between terminals 1 and 2.

If there is no continuity, replace the relay.

(2)

Check that there is no continuity between terminals
3 and 5.

If there is continuity, replace the relay.

(b)

Inspect the relay operation.
(1)

Apply battery positive voltage across terminals 1
and 2.

(2)

Using an ohmmeter, check that there is continuity
between terminals 3 and 5.

If there is no continuity, replace the relay.

INSPECTION

1.

REMOVE ENGINE COVER

Remove the 4 nuts and engine cover.

2.

REMOVE VSV

3.

INSPECT VSV

(a)

Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the terminals.
Resistance: 27 – 33

F)

If there is no continuity, replace the VSV.

(b)

Inspect the VSV for ground.
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.

If there is continuity, replace the VSV.

(c)

Inspect the VSV operation.
(1)

Check that air does not flows from the ports.

(2)

Apply battery positive voltage across the terminals.

(3)

Check that air flows from the ports.

If operation is not specified, replace the VSV.
