This diagnosis detects a very large leakage (fuel filler cap fell off etc.) in EVAP system between the fuel tank and EVAP canister purge volume control solenoid valve.
CAUTION:
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
CAUTION: Never remove fuel filler cap during the DTC Confirmation Procedure.
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
Check that EVAP hoses are connected to EVAP canister purge volume control solenoid valve properly.
TESTING CONDITION:
2.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
COOLAN TEMP/S: 0 - 70C (32 - 158F) INT/A TEMP SE: 0 - 60C (32 - 140F)
Follow the instructions displayed.
NOTE: If the engine speed cannot be maintained within the range displayed on the CONSULT screen
3.CHECK DTC
Check DTC.
4.PERFORM DTC CONFIRMATION PROCEDURE
With GST
NOTE: Be sure to read the explanation of EC-26, "SRT Set Driving Pattern" before driving vehicle.
Diagnosis Procedure
1.CHECK FUEL FILLER CAP DESIGN
2.CHECK FUEL FILLER CAP INSTALLATION
Check that the cap is tightened properly by rotating the cap clockwise.
3.CHECK FUEL FILLER CAP FUNCTION
Check for air releasing sound while opening the fuel filler cap.
4.CHECK FUEL TANK VACUUM RELIEF VALVE
5.CHECK EVAP PURGE LINE
Check EVAP purge line (pipe, rubber tube, fuel tank and EVAP canister) for cracks, improper connection or disconnection.
6.CLEAN EVAP PURGE LINE
Clean EVAP purge line (pipe and rubber tube) using air blower.
7.CHECK DRAIN FILTER
8.CHECK EVAP CANISTER VENT CONTROL VALVE
Check the following.
9.CHECK FOR EVAP LEAKAGE
10.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
With CONSULT
Vacuum should exist.
11.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
Without CONSULT
Vacuum should exist.
12.CHECK VACUUM HOSE
Check vacuum hoses for clogging or disconnection
13.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
With CONSULT
14.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
15.CHECK FUEL TANK TEMPERATURE SENSOR
16.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
17.CHECK EVAP/ORVR LINE
Check EVAP/ORVR line between EVAP canister and fuel tank for clogging, kinks, looseness and improper connection.
18.CHECK RECIRCULATION LINE
Check recirculation line between filler neck tube and fuel tank for clogging, kinks, cracks, looseness and improper connection.
19.CHECK REFUELING EVAP VAPOR CUT VALVE
20.CHECK INTERMITTENT INCIDENT
Component Inspection
FUEL TANK VACUUM RELIEF VALVE (BUILT INTO FUEL FILLER CAP)
1.CHECK FUEL FILLER CAP
Pressure: 15.3 - 20.0 kPa (0.156 - 0.204 kg/cm2, 2.22 -
2.90 psi)
Vacuum: −6.0 to −3.3 kPa (−0.061 to −0.034 kg/cm2,
−0.87 to −0.48 psi)
2.REPLACE FUEL FILLER CAP
Replace fuel filler cap.
CAUTION: Use only a genuine fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the MIL may illuminate.

WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur
from high pressure
coolant escaping from the radiator. Wrap a thick cloth around the radiator cap.
Slowly turn it a quarter
turn to allow built-up pressure to escape. C ...
