Carbon Canister Solenoid Valve
Inspection
Simulation Test
1. Inspect carbon canister solenoid valve. (Refer
to Troubleshooting, Inspection of Engine
Control System, Inspection of Carbon Canister
Solenoid Valve)
l If it is not as specified, perform further
inspection for the carbon canister solenoid
valve.
Airflow Inspection
Attention:
l Perform the following test only when
necessary.
1. Disconnect negative battery cable.
2. Remove carbon canister solenoid valve.
3. Inspect airflow of carbon canister solenoid
valve under the following conditions.
l If normal, inspect for open/short circuit,
improper layout of vacuum hose,
deformation or leakage.
l If abnormal, replace carbon canister
solenoid valve.
Open/Short Circuit Inspection
1. Inspect for any open or short circuit in the
following wiring harnesses.
l If any, repair or replace relevant wiring
harnesses.
Open Circuit
l GND circuit (between connector terminal 1
of carbon canister solenoid valve and ECU
connector terminal 46 through common
connector).
l Power circuit (between connector terminal 2
of carbon canister solenoid valve and
connector terminal E of main relay through
common connector).
Main relay
Short Circuit
l Circuit between carbon canister solenoid
valve connector terminal 2 and ECU
connector terminal 46 through common
connector.
2. Connect carbon canister solenoid valve.
3. Reconnect negative battery cable.
