  1. Perform the following SST (Evaporative Emission System Tester 134-01049) self-test: NOTE: If the tester does not work correctly during self-test, refer to the tester operators manual for more detailed procedures. Verify the gas cylinder valve is closed and the control located on the tester on the tester is in the TEST position. All tester display should be off at this time. Connect the long hose (part of SST ) to the tester. Connect the manifold assembly (part of SST ) to the long hose as shown. Open the gas cylinder valve and verify the gas cylinder regulator left gauge reads 10 to 12 psi (preset at factory). If not, refer to the tester operators manual to contact tester manufacturer. Press the ON/OFF switch to turn on the SST and make sure the left display reads 0.0. Turn the control valve on the tester to the FILL position. Verify the left display reading is within 13.9 to 14.0 inches of water. If not, adjust the pressure using the regulator knob located on the right side of the tester. Turn the control valve to TEST position and press the START switch After the 2-minute countdown (left display) is completed, the right display shows the total pressure loss for that period. A 0.5 inch of water, do one or more self-test. If the loss is more than 0.5 inch 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. If the fuel-filler cap is not genuine part, replace it.
  4. Turn the control valve tot he FILL position.
  5. Wait (maximum 20 seconds) until the left display reads 13.9 to 14 inches of water. If the reading is slightly below, adjust it using the regulator knob. If the reading s far below, the fuel-filler cap has leak. Replace it.
  6. Turn the control valve to the TEST position and press the START switch.
  7. After the 2-minute countdown (left display) is completed, check the test result (the failed/passed light on the tester). If the green light turns on, the fuel-filler cap is OK. If the red light turns on, the fuel-filler cap has leakage. Replace it.
  8. Close the gas cylinder valve.
  9. Turn the control valve tot he FILL position.
  10. Press the ON/OFF switch to turn off the tester.

Scheme 10: AIR FILTER INSPECTION
  1. Remove the air filter.
  2. Blow from port A and verify that there is airflow from port B. If not as specified, replace the air filter.
  3. Blow from port B and verify that thee is airflow from port A. If not as specified, replace the air filter.

Scheme 11: OBD II Regulation vehicle
  1. Remove the charcoal canister. (See «EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM COMPONENT REMOVAL/INSTALLATION»(ref-178040-S37799001532005061000000) .)
  2. Plug ports A and C, then blow air into port B. CAUTION: Do not apply the pressure more than 20 kPa {0.2 kgf/cm 2 , 2.8 psi} to the charcoal canister. Doing so will damage the charcoal canister.
  3. Verify that there is no air leakage from the case. If not as specified, replace the charcoal canister.

Scheme 12

Scheme 12: Non-OBD II Regulation Vehicle
  1. Remove the charcoal canister. (See «EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM COMPONENT REMOVAL/INSTALLATION»(ref-178040-S37799001532005061000000) .)
  2. Plug the atmosphere side pot and purge solenoid valve side pot of the charcoal canister.
  3. Blow air into the charcoal canister from the fuel tank side port and verify that there is no air leakage from the case. If not as specified, replace the charcoal canister.

  1. Disconnect the negative battery cable.
  2. Remove the fuel tank side of EVAP control system component. (See «EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM COMPONENT REMOVAL/INSTALLATION»(ref-178040-S37799001532005061000000) .)
  3. Remove in the order indicated in the illustration.
  4. Install in the reverse order of removal.
