This is the sensor to detect the fuel tank leakage in way which it measures the differential pressure between the

inside and outside of the fuel tank.

Check that fuel level is over 15%. If not, this inspection is not available. The vehicle must be running and at idle.

Don't forget it.

1. Prepare a voltmeter and connect it to FTP pins as shown.

2. After 20 min.' idling , inspect the voltage.

System voltage : 5V

At acceleration : Max. 4.5, Min. 0.5V

3. At idle make sure that voltage changes as rpm changes.

If voltage is not within specification, there is a leak. Inspect the fuel tank and hoses toward canister and

fuel neck. Then repair or replace relevant parts.
