Verification of the system variation of the valve timing system at Honda Accord VII

To test the VTEC system in the Honda Chord 7 system, you need to:

(1) Delete the distribution shaft of inlet valves.

2) Rotate the muff counterclockwise and make sure it is locked.

(3) If it is rotating, it must be replaced.

4) Install the filler holes in the preset wall near the muff, except one window to control the advance.

(5) Compressed air in the hole and check the pity of the rotation of the muff.

6) If it is not flat, it must be replaced.
