Pinpoint Test A : Slow To Fill: Notes
WARNING: This page is about a different car, the 2017 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
Normal Operation
Under normal operation, fuel should flow at a steady rate through the fuel tank filler pipe into the fuel tank. As fuel enters the fuel tank, air is vented through the filler pipe or the On-Board Refueling Vapor Recovery (ORVR) system.
This pinpoint test is intended to diagnose the following:
- Fuel tank filler pipe vent tube, if equipped
- Fuel tank filler pipe
- Evaporative Emission (EVAP) system
- Fuel tank inlet check valve (part of the fuel tank)
- Fuel level vent valve, if equipped
