Disconnect the vacuum hose from the throttle body, and connect a vacuum pump to the vacuum hose.
Check the following points when the engine is cold [engine coolant temperature 60°C(140°F) or below] and when it is warm [engine coolant temperature 80°C(176°F) or higher].
Engine operating condition | Applied vacuum | Result |
Idling | 50 kPa (7.3 psi) | Vacuum is held |
3,000 rpm |
Engine operating condition | Applied vacuum | Result |
Idling | 50 kPa (7.3 psi) | Vacuum is held |
Within 3 minutes after engine start at 3,000 rpm | Try to apply vacuum | Vacuum is released |
After 3 minutes have passed after engine start at 3,000 rpm | 50 kPa (7.3 psi) | Vacuum will be held momentarily, after which, it will be released |
