Purge Port Vacuum

CHECK CONDITION:

Engine coolant temperature: 85-95°C (185-205°F)





1. Disconnect the vacuum hose from the throttle body purge hose nipple and connect a hand vacuum pump to the nipple.





2. Start the engine and check to see that, after raising the engine speed by racing the engine, vacuum remains fairly constant.

NOTE: If there is no vacuum created, it is possible that the throttle body port may be clogged and require cleaning.
