Evaporative Emissions System Pinpoint Test 3: Unable To Refuel Vehicle

EVAPORATIVE EMISSIONS SYSTEM PINPOINT TEST 3: UNABLE TO REFUEL VEHICLE

PINPOINT TEST 3		UNABLE TO REFUEL VEHICLE
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 Tester to the fuel filler pipe. Close the canister vent solenoid. Access PCM PID FTP V. Pressurize the EVAP system to 3.48 kPa (14 in-H2O). Is PID FTP V reading 3.11 kPa to 3.86 kPa (12.5 to 15.5 in-H2O) (4.22 to 4.90 volts)?	Yes	Go to next step.
1		No	Install a new fuel filler pipe and fuel filler pipe check valve. Carry out the evaporative emission repair verification drive cycle. See DRIVE CYCLES .
2	TEST THE EVAP SYSTEM FOR RESTRICTION Connect the EVAP System Leak Tester to the fuel filler pipe. Attempt to pressurize the EVAP system to 3.48kPa (14 in-H2O). Does the system pressurize?	Yes	Go to next step.
2		No	Carry out the EVAP system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, carry out the EVAP system repair verification drive cycle. See DRIVE CYCLES .
3	TEST FOR CANISTER VENT HOSE BLOCKAGE Remove the canister vent hose from the canister vent solenoid. Connect the Evaporative Emission System Tester to the fuel filler pipe. Attempt to pressurize the EVAP system to 3.48kPa (14 in-H2O). Does the system pressurize?	Yes	Go to next step.
3		No	Replace the canister vent hose. Perform the evaporative emission system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, carry out the EVAP system repair verification drive cycle. See DRIVE CYCLES .
4	TEST FOR EVAP CANISTER BLOCKAGE Remove the canister vent solenoid from the EVAP canister. Connect the Evaporative Emission System Tester to the fuel filler pipe. Attempt to pressurize the EVAP system to 3.48kPa(14in-H2O). Does the system pressurize?	Yes	Go to next step.
4		No	Install a new canister vent solenoid. Perform the EVAP system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, carry out the EVAP system repair verification drive cycle. See DRIVE CYCLES .
5	TEST FOR EVAP CANISTER BLOCKAGE Disconnect the EVAP canister tube from the EVAP canister. Connect the Evaporative Emission System Tester to the fuel filler pipe. Attempt to pressurize the EVAP system to 3.48kPa(14in-H2O). Does the system pressurize?	Yes	Go to next step
5		No	Install a new EVAP canister. Perform the EVAP system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, perform the EVAP system repair verification drive cycle. See DRIVE CYCLES .
6	TEST FOR FUEL VAPOR VALVE TUBE ASSEMBLY BLOCKAGE Disconnect the EVAP canister tube from the fuel vapor valve tube assembly. Connect the Evaporative Emission System Tester to the fuel filler pipe. Attempt to pressurize the EVAP system to 3.48 kPa (14 in-H2O). Does the system pressurize?	Yes	Install a new fuel vapor valve tube assembly. Perform the EVAP system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, perform EVAP System Repair Verification Drive Cycle. See DRIVE CYCLES .
6		No	Install a new EVAP canister tube. Perform the EVAP system leak test. See EVAPORATIVE EMISSION SYSTEM LEAK TEST . If the system passes the leak test, perform EVAP System Repair Verification Drive Cycle. See DRIVE CYCLES .
