Inspection
[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/cm², 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/cm², 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/cm², Min. 67.7 kPa) | Vacuum will be held momentarily, after which, it will be released
[PCSV Inspection]
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.
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 ~ 26.0Ω [20°C(68°F)]
[EVAP. Leakage Test]
1. | Select "Evap. Leakage Test".
2. | Proceed with the test according to the screen introductions.
