VTEC Rocker Arm Test

Special Tools Required
• Air pressure regulator 07AAJ-PNAA101
• VTEC air adapter 07ZAJ-PNAA101
• VTEC air stopper 07ZAJ-PNAA200
• Air joint adapter 07ZAJ-PNAA300
1. Start the engine, and let it run for 5 minutes, then
turn the ignition switch to LOCK (0).
2. Remove the cylinder head cover (see page 6-25).
3. Set the No. 1 piston at top dead center (TDC) (see
step 5 on page 6-13).
4. Move the secondary rocker arm (A) for the No. 1
cylinder. The secondary rocker arm should move
independently of the mid rocker arm (B).
• If the secondary rocker arm does not move,
remove the mid, primary, and secondary rocker
arms as an assembly, and check that the pistons
in the rocker arms move smoothly. If any rocker
arm needs replacing, replace the mid, primary,
and secondary rocker arms as an assembly, then
retest.
• If the secondary rocker arm moves freely, go to
step 5.
