Pinpoint Test 1: Excessive Fuel Odor

PINPOINT TEST 1 - EXCESSIVE FUEL ODOR

PINPOINT TEST 1	EXCESSIVE FUEL ODOR
STEP	INSPECTION		ACTION
1	TEST THE EVAP RUNNING LOSS SYSTEM MONITOR Perform EVAP Running Loss System Repair Verification Drive Cycle. See DRIVE CYCLES . Are PCM DTCs retrieved?	Yes	For DTC P0442, P0455, P1443 or P1450, refer to appropriate DTC Troubleshooting.
1		No	Go to next step.
2	TEST FOR RESTRICTIONS IN THE EVAP SYSTEM FROM THE EVAP TEST PORT THROUGH THE CANISTER VENT SOLENOID Connect the EVAP System Leak Tester to the EVAP test port. Key ON, Engine OFF (KOEO). Close the Canister Vent, (CV) solenoid by accessing Output Test Mode. Attempt to pressurize the EVAP system to 3.48 kPa (14 in-H2O). Press STOP (#4) on the NGS Tester to open the CV solenoid. Does the pressure drop immediately?	Yes	Perform EVAP Emission System Leak Test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, perform EVAP Running Loss System Repair Verification Drive Cycle. See DRIVE CYCLES . Go to next step
2		No	Go to PINPOINT TEST 2: HISS WHEN OPENING FUEL CAP .
3	TEST FOR A RESTRICTED TUBE BETWEEN THE FUEL TANK AND THE EVAP CANISTER Connect the EVAP System Leak Tester to the fuel filler pipe. Attempt to pressurize the EVAP system to 3.48 kPa (14 in-H2O). Does the pressure drop immediately?	Yes	Perform EVAP Emission System Leak Test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, perform EVAP Running Loss System Repair Verification Drive Cycle. See DRIVE CYCLES .
3		No	Go to next step.
4	TEST FOR EVAP CANISTER TUBE OR FUEL VAPOR VENT VALVE ASSEMBLY BLOCKAGE Disconnect the fuel vent valve assembly from the EVAP canister tube. Connect the EVAP System Leak Tester to the fuel filler pipe. Attempt to pressurize the EVAP system to 3.48 kPa (14 in-H2O). 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. Perform EVAP Emission System Leak Test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, perform EVAP Running Loss System Repair Verification Drive Cycle. See DRIVE CYCLES .
4		No	Install new fuel vapor vent valve(s) or assembly. Perform EVAP Emission System Leak Test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, perform EVAP Running Loss System Repair Verification Drive Cycle. See DRIVE CYCLES .
