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.
