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.
  1. At Cold Engine (Engine Coolant Temperature < 60°C (140°F)) OPERATING CONDITION REFERENCE Engine Operating Condition Applied Vacuum Result Idle 0.5 kgf/cm 2 (50 kPa, 7.3 psi) Vacuum is held 3, 000 RPM
