Evaporative Emission Control System: Diagnosis Kia Soul I рестайлинг

(System Inspection)

1. Disconnect the vapor hose from the intake manifold and connect a vacuum pump to the nipple on the intake manifold. At Cold Engine [Engine Coolant Temperature < 60°C(140°F)] Engine Operating Condition Applied Vacuum Result Idle Min. 20 inHg (Min. 0.7 kgf/cm 2 , Min. 67.7 kPa) Vacuum is held 3, 000rpm
2. Check the following points with applied vacuum at the purge control solenoid valve (PCSV). At Warmed Engine [Engine Coolant Temperature > 80°C(176°F)] Engine Operating Condition Applied Vacuum Result Idle Min. 20 inHg (Min. 0.7 kgf/cm 2 , Min. 67.7 kPa) Vacuum is held Within 3 minutes after engine start at 3, 000 rpm Try to apply vacuum Vacuum is released In 3 minutes after engine start at 3, 000 rpm Min. 20 inHg (Min. 0.7 kgf/cm 2 , Min. 67.7 kPa) Vacuum will be held momentarily, after which, it will be released

Scheme 21

1. Turn ignition switch OFF and disconnect the negative (-) battery cable.
2. Disconnect the PCSV connector (A).
3. Disconnect the vapor hose (B) which is connected to the intake manifold from the PCSV. [1.6 GDI] [2.0 MPI]
4. After connecting a vacuum pump to the nipple, apply vacuum.
5. With the PCSV control line grounded, check the valve operation with battery voltage applied to the PCSV(Open) and removed(Closed). Battery Voltage Valve Vacuum Connected Open Released Disconnected Close Maintained
6. Measure the coil resistance of the PCSV. Specifications: 22.0 ~ 26.0ohms [20°C(68°F)]

Scheme 23

1. Select "Evap. Leakage Test".
2. Proceed with the test according to the screen introductions.

Scheme 24

1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2. Remove the fuel tank. (Refer to " «FUEL TANK»(ref-537217-S35824273632013032200000) " in FL group)
3. Disconnect the vapor hoses (A).
4. Remove the canister close valve (B) after removing the installation bolts.
5. Remove the canister assembly (C) in the direction of the arrow after removing the installation bolts (D).

Scheme 25

1. Check for the following items visually. Cracks or leakage of the canister Loose connection, distortion, or damage of the vapor hose/tube Canister <--> Atmosphere Canister <--> Intake manifold Canister <--> Fuel tank
