EVAP Service Port

Positive pressure is delivered to the EVAP system through the EVAP service port. If fuel vapor leakage in the EVAP system occurs, use a leak detector to locate the leak.

CAUTION:
  • Never use compressed air or a high pressure pump.
  • Do not exceed 4.12 kPa (0.042 kg/cm2 , 0.6 psi) of pressure in EVAP system.
NOTE:
  • Do not start engine.
  • Improper installation of EVAP service port adapter to the EVAP service port may cause a leak.
