DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

V
(EVAP canister purge 
volume control solenoid 
valve)

the vehicle is stopped while the engine is 
running, even when EVAP canister purge 
volume control solenoid valve is completely 
closed.

• EVAP control system pressure sensor
• EVAP canister purge volume control sole-

noid valve
(The valve is stuck open.)

• EVAP canister vent control valve
• EVAP canister
• Hoses

(Hoses are connected incorrectly or 
clogged.)

B

The canister purge flow is detected during 
the specified driving conditions, even when
