Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The EVAP canister shut-off valve is open and the fuel tank system is vented. The canister purge (CP) valve is pulsed and because of the vacuum in the intake manifold the engine starts to suck air through the EVAP canister.
Because the EVAP canister shut-off valve is open the pressure in the fuel tank will start to drop slowly, if the pressure in the fuel tank drops too rapidly diagnostic trouble code (DTC) EFI-614 (EVAP canister shut-off valve, flow fault) is stored.

Substitute value
None.
