Evaporative (EVAP) emission system includes following components: fuel tank, EVAP vent solenoid, fuel tank pressure sensor, fuel pipes and hoses, vapor lines, fuel cap, EVAP emission canister, purge lines, and EVAP purge solenoid.
A leaking purge solenoid, EVAP purge and engine vacuum lines switched at EVAP purge solenoid, or EVAP purge solenoid driver circuit shorted to ground, will set DTC. Condition for setting DTC is when a continuous open purge flow condition is detected during the diagnostic test, fuel tank pressure decreases to less than -11 in. H2O.
