1. Disconnect a vacuum hose (with a red strip) from throttle knot and instead of it connect the vacuum pump with a vacuum hose. |
2. Check the following parameters on the cold engine at temperature of cooling liquid less 40°C and on the hot engine at temperature of cooling liquid more 80°C.
At operation of the cold engine in a mode of idling and frequency of 3000 mines–1 at creation of depression of 50 kPas the vacuum should be supported.
At operation of the hot engine in an idling mode at creation of depression of 50 kPas the vacuum should be supported.
During 3 mines after increase in frequency of rotation to 3000 mines of-1 hot engine and attempt to change depression the vacuum should be absent.
Through 3 mines after increase in frequency of rotation to 3000 mines of-1 hot engine and creation of depression of 50 kPas the vacuum should is supported quickly then should be absent.
