Inspection

[System Inspection]

1. | Disconnect the vapor hose from the throttle body and connect a vacuum pump to the nipple on the throttle body.

2. | Check the following points with applied vacuum using a vacuum pump. · At Cold Engine [Engine Coolant Temperature < 60°C(140°F)]

Engine Operating Condition | Applied Vacuum | Result
Idle | 14.5 inHg (0.5 kgf/cm², 49.0kPa) | Vacuum is held
3,000rpm

· At Warmed Engine [Engine Coolant Temperature > 80°C(176°F)]

Engine Operating Condition | Applied Vacuum | Result
Idle | 14.5 inHg (0.5 kgf/cm², 49.0kPa) | 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 | 14.5 inHg (0.5 kgf/cm², 49.0kPa) | 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: 19.0 ~ 22.0Ω [20°C(68°F)]

[EVAP. Leakage Test]

1. | Select "Evap. Leakage Test".

2. | Proceed with the test according to the screen introductions.
