DTC DETECTION LOGIC
This diagnosis detects leakage in the EVAP purge line using engine intake manifold vacuum.
If pressure does not increase, the ECM will check for leakage in the line between the fuel tank and EVAP canister purge volume control solenoid valve, under the following "Vacuum test" conditions.
The EVAP canister vent control valve is closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve will then be opened to depressurize the EVAP purge line using intake manifold vacuum. After this occurs, the EVAP canister purge volume control solenoid valve will be closed.
CAUTION:
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
TESTING CONDITION:
NOTE: Check that EVAP hoses are connected to EVAP canister purge volume control solenoid valve properly.
2.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
COOLAN TEMP/S: 0 - 70C (32 - 158F) INT/A TEMP SE: 0 - 30C (32 - 86F)
Follow the instructions displayed.
NOTE: If the engine speed cannot be maintained within the range displayed on the CONSULT screen
3.PERFORM COMPONENT FUNCTION CHECK
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 FOR EVAP LEAKAGE
6.CHECK DRAIN FILTER
7.CHECK EVAP CANISTER VENT CONTROL VALVE
Check the following.
Refer to FL-16, "Removal and Installation".
8.CHECK IF EVAP CANISTER IS SATURATED WITH WATER
Remove EVAP canister with EVAP canister vent control valve and EVAP control system pressure sensor attached.
9.CHECK EVAP CANISTER
Weigh the EVAP canister with the EVAP canister vent control valve and EVAP control system pressure sensor attached.
The weight should be less than 2.1 kg (4.6 lb).
10.DETECT MALFUNCTIONING PART
Check the following.
11.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
With CONSULT
Vacuum should exist.
12.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
Without CONSULT
Vacuum should exist.
13.CHECK VACUUM HOSE
Check vacuum hoses for clogging or disconnection.
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 PURGE LINE
Check EVAP purge line (pipe, rubber tube, fuel tank and EVAP canister) for cracks or improper connection.
18.CLEAN EVAP PURGE LINE
Clean EVAP purge line (pipe and rubber tube) using air blower.
19.CHECK EVAP/ORVR LINE
Check EVAP/ORVR line between EVAP canister and fuel tank for clogging, kinks, looseness and improper connection.
20.CHECK RECIRCULATION LINE
Check recirculation line between filler neck tube and fuel tank for clogging, kinks, cracks, looseness and improper connection.
21.CHECK REFUELING EVAP VAPOR CUT VALVE
22.CHECK FUEL LEVEL SENSOR
23.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. Refer to FL-10, "Exploded View".
CAUTION: Use only a genuine fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the MIL may illuminate.
