INSPECTION
1. REMOVE VSV
2. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is a continuity between
the terminals.
Resistance: 24 - 30 W at 20°C (68°F)
If there is no continuity, replace VSV.
3. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between
each terminal and the body.
If there is a continuity, replace VSV.
4. INSPECT VSV OPERATION
(a) Check that air flows from the ports A to B.
(b) Apply the battery positive voltage across the terminals.
(c) Check that air does not flow from the ports A to B.
If operation is not as specified, replace VSV.
5. REINSTALL VSV

INSPECTION
1. REMOVE VSV
2. INSPECT VSV
(a) Inspect VSV for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the terminals.
Resistance: 30 - 36 W at 20°C (68°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 a continuity, replace the VSV.
(c) Inspect the VSV operation.
(1) Check that air flows from the ports E to F.
(2) Apply the battery positive voltage across the termi-
nals.
(3) Check that air flows from the ports E to F.
If operation is not as specified, replace VSV.
3. REINSTALL VSV

INSPECTION
1. INSPECT POWER SOURCE VOLTAGE OF VAPOR
PRESSURE SENSOR
(a) Disconnect the vapor pressure sensor connector.
(b) Turn the ignition switch ON.
(c) Using a voltmeter, measure the voltage between connec-
tor terminal 1 and 3 of the wiring harness side.
Voltage: 4.5 - 5.5 V
(d) Turn the ignition switch OFF.
(e) Reconnect the vapor pressure sensor connector.
2. INSPECT POWER OUTPUT OF VAPOR PRESSURE
SENSOR
(a) Turn the ignition switch ON.
(b) Remove the fuel tank cap.
(c) Connect a voltmeter to terminal 2 and 3, and measure the
output voltage.
Voltage: 3.0 - 3.6 V
(d) Reinstall the fuel tank cap.
(e) Turn the ignition switch OFF.

INSTALLATION
NOTICE:

Never use SRS parts from another vehicle. When re-
placing parts, replace them with new parts.

Never reuse the airbag sensor assembly involved in
a collision when the airbag has deployed.

Never repair a sensor in order to reuse it.
HINT:
For step 2 to 6, refer to page BO-91.
1. INSTALL AIRBAG SENSOR ASSEMBLY
(a) Install the airbag sensor assembly with the 3 bolts.
Torque: 17.5 N´m (178 kgf´cm, 13 ft´lbf)
(b) Connect the airbag sensor connectors.
NOTICE:

Connection of the connector is done after the sensor
assembly has been installed.

Make sure the sensor assembly is installed with the
specified torque.

If the sensor assembly has been dropped, or there are
cracks, dents or other defects in the case, bracket or
connector, replace the sensor assembly with a new
one.

When installing the sensor assembly, take care that
the SRS wiring does not interfere with other parts and
is not pinched between other parts.

After installing, shake the sensor assembly to check
that there is no looseness.
