CUSTOMER CONCERN Customer reports the fuel-pump nozzle repeatedly shuts off while refueling. DTC P1450 may be stored in the Powertrain Control Module. CAUSE Inspection confirmed a restriction in the EVAP fresh-air pipe, preventing the fuel-tank vapor system from venting properly during refueling. CORRECTION Clean the restricted EVAP fresh-air pipe, remove the obstruction, and verify normal refueling and EVAP system operation.
