Inspection

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

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

   
   · With a warm engine [engine coolant temperature > 80 °C]

   Engine Operating Condition	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
