CAUTION: The canister vent solenoid must not be energized for more than nine minutes at one time.

Failure to allow the component to cool may create a false failure in the diagnostics, causing unnecessary repairs.
1. Connect the scan tool and select the output test mode.
2. If PID monitors are not active, select PIDs.
3. Select the fuel tank pressure (FTP) and the volts (V) parameter identification (PID) for monitoring.
