Pinpoint Test 2: Excessive Fuel Odor

PINPOINT TEST 2: EXCESSIVE FUEL ODOR

PINPOINT TEST 2 EXCESSIVE FUEL ODOR
STEP INSPECTION ACTION
1 TEST THE EVAPORATIVE EMISSION (EVAP) RUNNING LOSS SYSTEM MONITOR Yes See DIAGNOSTIC TROUBLE CODE NUMBERS  .
No Go to next step.
2 TEST FOR RESTRICTIONS IN THE EVAP SYSTEM FROM THE EVAPORATIVE EMISSION TEST PORT THROUGH THE CANISTER VENT SOLENOID
  • Connect the Evaporative Emission System Leak Tester to the evaporative emissions test port.
  • Attempt to pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
  • Does the pressure drop immediately? 
 Yes CARRY OUT the evaporative emission system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST  on. If the system passes the leak test, CARRY OUT the evaporative emission repair verification drive cycle. See EVAPORATIVE EMISSION REPAIR VERIFICATION DRIVE CYCLE  . Go to next step.
No GO to PINPOINT TEST 1: HISS WHEN OPENING FUEL CAP  .
3 TEST FOR A RESTRICTED TUBE BETWEEN THE FUEL TANK AND THE EVAPORATIVE EMISSION CANISTER
  • Connect the Evaporative 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 pressure drop immediately? 
 Yes 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 EVAP CANISTER TUBE OR FUEL VAPOR VENT VALVE ASSEMBLY BLOCKAGE
  • Disconnect the fuel vapor vent valve assembly from the EVAP canister tube.
  • Connect the EVAP System Leak Tester to the fuel filler pipe.
  • Pressurize the EVAP system to 3.48 kPa (14 inches H2 O).
  • Does the pressure drop immediately? 
 Yes INSTALL a new EVAP canister tube and/or fuel vapor tube(s) between the fuel tank and the EVAP canister and bracket assembly. 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 fuel vapor vent valve(s) or assembly. 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  .
