LEAKAGE INSPECTION
1. Perform the following
SST
(Evaporative Emission System Tester 134-01049) self-test:
1. Verify that the gas cylinder valve is closed and the control valve located on the tester is in the
TEST position. All tester displays should be off at this time.
2. Connect the long hose (part of
SST
) to the tester.
3. Connect the manifold assembly (part of
SST
) to the long hose as shown.
4. Open the gas cylinder valve and verify the gas cylinder regulator left gauge reads
69-82 kPa {0.71-
0.83 kgf/cm
2
, 10-12 psi}
(preset at factory).
z
If not, refer to the tester operators manual to contact tester manufacturer.
5. Press the ON/OFF switch to turn on the
SST
and make sure the left display reads
0.0.
6. Turn the control valve on the tester to the FILL position.
7. Verify the left display reading is
within 13.9
to
14.0
in of water.
z
If not, adjust the pressure using the regulator knob located on the right side of the tester.
8. Turn the control valve to TEST position and press the START switch.
9. After the
2-min
countdown (left display) is completed, the right display shows the total pressure
loss for that period. A
0.5
in of water loss is acceptable on the self-test.
z
If the loss is
more than 0.5
in of water, do one or more self-test. If the failed test repeats,
check for leak using the ultrasonic leak detector (part of
SST
).
2. Press the RESET switch to set the left display reading to
0.0.
3. Connect the fuel cap receiver assembly (part of
SST
) to the manifold assembly and fuel-filler cap from
the vehicle.
z
If the fuel-filler cap is not a genuine part, replace it.

If the tester does not work correctly during self-test, refer to the
tester operators manual for more detailed procedures.
