With Federal or Canada Emissions

1. Disconnect the vacuum hose (red stripes) from the throttle body and connect it to a hand vacuum pump.





2. Plug the nipple from which the vacuum hose was removed.
3. When the engine is cold and hot, apply a vacuum while the engine is idling, and check the condition of the engine and the vacuum.

When engine is cold [Engine coolant temperature: 40°C (104°F or less]

Vacuum Engine status Normal condition
53 kPa 3,500 r/min Vacuum is maintained
(15.7 in.Hg.)

When engine is hot [Engine coolant temperature: 80°C (17609 or higher]

Vacuum Engine status Normal condition
53 kPa Idling Vacuum is maintained
(15.7 in.Hg) 3,500 r/min Vacuum will leak for approximately 3 minutes after the engine is started. After 3 minutes have elapsed, the vacuum will be maintained momentarily, after which it will again leak. *


NOTE: * The vacuum will leak continuously if the atmospheric pressure is approximately 77 kPa (22.8 in.Hg) or less, or the temperature of the intake air is approximately 50°C (122°F) or higher.
