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 applying vacuum using the vacuum pump. · At Cold Engine [Engine Coolant Temperature < 60°C(140°F)] Engine Operating Condition Applied Vacuum Result Idle 0.5kgf/cm² (50kPa,7.3psi) Vacuum is held 3,000rpm · At Warmed Engine [Engine Coolant Temperature > 80°C(176°F)] Engine Operating Condition Applied Vacuum Result Idle 0.5kgf/cm² (50kPa,7.3psi) 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 0.5kgf/cm² (50kPa,7.3psi) Vacuum will be held momentarily, after which, it will be released

1.	Turn ignition switch OFF and disconnect the negative (-) battery cable.

2.	Disconnect the PCSV connector.

3.	Disconnect the vapor hose which is connected with 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 valve operation when applying battery voltage to the PCSV or not. Battery Voltage Valve Vacuum Connected Open Released Disconnected Close Maintained

6.	Measure the coil resistance of the PCSV. Specification: 19.0 ~ 22.0Ω [20°C(68°F)]
