Concern
| Causes
|
DEFINITION: Difficulty in refueling the vehicle
when equipped with an ORVR fuel system.
|
Difficult to fill
|
| • | The check valve is stuck closed. |
| • | The fill limiter vent valve is stuck closed. |
| • | The evaporative emission (EVAP) canister is restricted. |
| • | The EVAP-canister vent solenoid is stuck closed. |
| • | Restricted vapor lines |
| • | Fuel with high Reid Vapor Pressure characteristics |
| • | High fuel temperatures |
| • | The fuel filler hose or the pipe is pinched, is kinked, or is
blocked. |
|
Over-fill
|
| • | The pressure relief valve in the fill limiter vent valve is stuck
open. |
| • | The pressure relief valve in the fill limiter vent valve is leaking. |
| • | The fill limiter vent valve is stuck open. |
| • | The fill limiter vent valve is leaking. |
|
Premature shut-off of the fuel-dispensing nozzle
|
| • | The fill limiter vent valve is stuck closed. |
| • | A restricted EVAP canister |
| • | A stuck-closed EVAP-canister vent solenoid. |
| • | Restricted fuel vapor lines |
| • | Fuel with high Reid Vapor Pressure characteristics |
| • | High fuel temperatures |
|
Fuel Backflow
|
| • | The check valve is stuck open. |
| • | The check valve is stuck closed. |
| • | The check valve is leaking. |
| • | Fuel with high Reid Vapor Pressure characteristics |
| • | High fuel temperatures |
|
Liquid fuel in the EVAP canister.
|
| • | The fill limiter vent valve is stuck open. |
| • | The fill limiter vent valve is leaking. |
|
Liquid fuel leak
|
| • | The pressure relief valve in the fill limiter vent valve is stuck
open. |
| • | The pressure relief valve in the fill limiter vent valve is leaking. |
| • | A torn fuel filler hose or a loose fuel filler hose |
| • | The fill limiter vent valve is stuck open. |
|
Fuel Odor
|
| • | Pressure relief in the fuel limiter vent valve stuck open. |
| • | The pressure relief valve in the fill limiter vent valve is leaking. |
| • | A fuel-saturated EVAP canister |
