1. 1
   Disconnect the vapor hose from the throttle body and connect a vacuum pump to the nipple on the throttle body.
2. 2
   Using the vacuum pump, check the following items by applying vacuum. • With cold engine [engine coolant temperature < 60 °C]

   Engine Status	Applied vacuum	Result
   Idle	0.5 kgf/cm² (50 kPa, 7.3 psi)	Vacuum is applied
   3000 rpm

   
   • With warm engine [engine coolant temperature > 80 °C]

   Engine Status	Applied vacuum	Result
   Idle	0.5 kgf/cm² (50 kPa, 7.3 psi)	Vacuum is applied
   Within 3 minutes after starting the engine at 3000 rpm	Try to apply vacuum	Vacuum is released
   3 minutes after starting the engine at 3000 rpm	0.5 kgf/cm² (50 kPa, 7.3 psi)	Vacuum will be held momentarily, then released

3. 3
   Turn the ignition switch OFF and disconnect the negative (-) battery cable.
4. 4
   Disconnect the PCSV connector (A).
5. 5
