Fuel Tank Pressure Sensor: Testing and Inspection

CIRCUIT DIAGRAM








Inspection
Check to look that fuel level is over 15%. If not, this inspection is not available.

The vehicle must be in turn-on and at idle. Don't forget it.
1. Prepare a voltmeter and connect it to FTP pins as shown.
2. After 20 minutes idling, inspect the voltage.

System voltage 5 V At accelerate Max. 4.5, Min. 0.5 V

3. At idle, inspect that voltage fluctuates up to accelerate rpm up and down.

NOTE: If voltage is not within specifications, there is leakage. Inspect the fuel tank and hoses toward canister and fuel neck. Then repair or replace relevant parts.
