PINPOINT TEST 3: UNABLE TO REFUEL (ORVR)

PINPOINT TEST 3 UNABLE TO REFUEL (ORVR)
STEP INSPECTION ACTION
1 TEST THE FUEL FILLER PIPE AND THE FUEL FILLER PIPE CHECK VALVE
  • Remove the fuel filler cap.
  • Connect the Evaporative Emission System Leak Tester to the fuel filler pipe.
  • Close the canister vent solenoid. See CANISTER VENT SOLENOID CLOSING PROCEDURE  .
  • Access PCM PID FTP V.
  • Pressurize the EVAP System to 3.48 kPa (14 inches H2 O).
  • Is PID FTP V reading 3.11 kPa to 3.86 kPa (12.5 to 15.5 inches H 2O) (4.22 to 4.90 volts)? 
 Yes Go to next step.
No INSTALL a new fuel filler pipe and the fuel filler pipe check valve. CARRY OUT the evaporative emissions repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  .
2 TEST THE EVAP SYSTEM FOR RESTRICTION
  • Open the canister vent solenoid.
  • Attempt to pressurize the EVAP System to 3.48 kPa (14 inches H2 O).
  • Does the system pressurize? 
 Yes Go to next step.
No CARRY OUT the evaporative emissions system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST  . If the system passes the leak test, Carry out the evaporative emissions repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  .
3 TEST FOR FUEL VAPOR CONTROL VALVE TUBE ASSEMBLY BLOCKAGE
G03723752
  • Disconnect the evaporative emission canister purge outlet tube.
  • Connect the Evaporate Emission System Leak Tester to the fuel filler pipe.
  • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
  • Does the system pressurize? 
 Yes INSTALL a new fuel tank assembly. See FUEL TANK . CARRY OUT the evaporative emission system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST  . If the system passes the leak test, Carry out the evaporative emission repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  .
No Go to next step.
4 TEST FOR CHECK VALVE BLOCKAGE
G03723753
  • Remove the EVAP canister and bracket assembly from the vehicle. See EVAPORATIVE EMISSION CANISTER .
  • Connect the Evaporative Emission System Leak Tester to the EVAP canister purge outlet tube.
  • Disconnect the check valve assembly.
  • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
  • Does the system pressurize? 
 Yes Go to next step.
No INSTAL a new check valve. CARRY OUT the evaporative emission system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST  . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  .
5 TEST FOR DUST SEPARATOR BLOCKAGE
G03723754
  • Disconnect the dust separator and hose assembly.
  • Connect the Evaporative Emission System Leak Tester to the EVAP canister purge outlet tube.
  • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
  • Does the system pressurize? 
 Yes Go to next step.
No INSTALL a new dust separator and hose assembly. See DUST SEPARATOR . CARRY OUT the evaporative emission system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST  . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  .
6 TEST FOR EVAPORATIVE EMISSION CANISTER VENT SOLENOID BLOCKAGE
G03723755
  • Remove the evaporative emission canister vent solenoid.
  • Connect the Evaporative Emission System Leak Tester to the EVAP canister purge outlet tube.
  • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
  • Does the system pressurize? 
 Yes Go to next step.
No INSTALL a new evaporative emission canister vent solenoid. CARRY OUT the evaporative emission system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST  . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  .
7 TEST FOR EVAPORATIVE EMISSION CANISTER BLOCKAGE
G03723756
  • Remove the evaporative emission canister purge outlet tube.
  • Connect the Evaporative Emission System Leak Tester to the EVAP canister purge outlet tube.
  • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
  • Does the system pressurize? 
 Yes INSTALL a new evaporative emission canister purge outlet tube. CARRY OUT the evaporative emission system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST  . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  .
No INSTALL a new evaporative emission canister. CARRY OUT the evaporative emission system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST  . If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  .
