indicating the system is being pressurized. Continue to depress the remote starter button until the ball stops descending. Once the indicator ball has

Leak Verification After Repair
a.
If the measurement is below the indicator flag the system has passed. The test procedure is complete. Remove the Smoke Machine Test
equipment from the vehicle and reconnect the large EVAP Canister Purge Valve manifold vacuum hose and the test port's green cap.

Using WDS Datalogger or NGS select the FTPV PID.
10.
Remove Fuel Cap and turn the vehicle's ignition switch to the run position and check the FTPV PID.
11.
The nominal value for the FTPV PID is 2.6V. If the value is greater than 2.8V or less than 2.4V, the FTP sensor is out of range and should be
replaced. Verify the repair by checking to see if the new sensor is in range. For all except Windstar, LS, Thunderbird & PZEV Focus - if the
sensor is within range, the concern is no longer present. (Windstar, LS, Thunderbird & PZEV Focus go to Step 12.)
12.
For Windstar, LS, Thunderbird & PZEV Focus only verify that filler neck clamps are in good working order and tightened. Repair as necessary. If
no problem is found with clamps, replace the fuel cap.
