EVAP system leak inspection using leak tester
1. Perform the following SST (EVAP System Tester 134-01049) self-test:
NOTE:
1. Verify that the control valve on the panel is in the HOLD position then open the nitrogen bottle
valve.
2. Connect the vehicle interface hose (part of the SST ) to the SELF-TEST port located on the control
panel. Hand tighten the fitting. (Do not overtighten.)
3. Turn the control valve to the TEST position.
4. The gauge should read 331-381 mm {13-15 in} of water.
If the gauge is not reading in this range, adjust the pressure by turning the black knob on the
low pressure regulator at the nitrogen bottle.
5. Turn the control valve to the HOLD position.
6. Verify that the gauge holds pressure and that the flow meter reads no flow.
If there is no drop in pressure and no flow, the tester passes the self-test.
If the gauge leaks down, refer to the tester operators manual.
