Engine Compression Inspection
NOTE: After this inspection, you must reset the engine
control module (ECM)/powertrain control module
(PCM), otherwise the ECM/PCM will continue to stop
the fuel injectors from operating. 1. Warm up the engine to normal operating temperature (cooling fan comes on).
2. Turn the ignition switch to LOCK (0).
3. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
4. Turn the ignition switch to ON (II).
5. Make sure the HDS communicates with the vehicle and the ECM/PCM. If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
6. Select ALL INJECTORS STOP in the PGM-FI, INSPECTION menu with the HDS.
7. Turn the ignition switch to LOCK (0).
8. Remove the four ignition coils (see page 4-21).
9. Remove the four spark plugs.
10. Attach the compression gauge to a spark plug hole. 11. Step on the accelerator pedal to open the throttle
fully, then crank the engine with the starter motor,
and measure the compression.
12. Measure the compression on the remaining cylinders.
13. If the compression is not within specifications, check the following items, then remeasure the
compression.
 Incorrect valve clearance
 Confirmation of cam timing
 Damaged or worn cam lobes
 Damaged or worn valves and seats
 Damaged cylinder head gasket
 Damaged or worn piston rings
 Damaged or worn piston and cylinder bore
14. Remove the compression gauge from the spark plug hole.
15. Install the four spark plugs.
16. Install the four ignition coils (see page 4-21).
17. Select the ECM/PCM reset (see page 11-4) in the PGM-FI INSPECTION menu to cancel ALL
INJECTORS STOP with the HDS.

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 6-36).
3. Set the No. 1 piston at top dead center (TDC) (see step 5 on page 6-18).
4. Move the intake primary rocker arm (A) for the No. 1 cylinder. The primary rocker arm should
move independently of the intake secondary rocker
arm (B).
 If the intake primary rocker arm moves freely, go to step 5.
 If the intake primary rocker arm do not move independently, remove the primary and
secondary rocker arms as an assembly and check
that the pistons in the secondary and primary
rocker arms move smoothly. If any rocker arm
needs replacing, replace the primary and
secondary rocker arms as an assembly, then
retest. 5. Repeat step 4 on the remaining intake primary
rockerarmswitheachpistonatTDC.Whenallthe
primary rocker arms pass the test, go to step 6.
6. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa
(4 kgf/cm , 57 psi).
7. Inspect the valve clearance (see page 6-12).
8. Remove the sealing bolt (A) from the relief hole, and install the VTEC air stopper (B).
9. Remove the No. 2 and No. 3 camshaft holder bolts, and install the VTEC air adapters (C) finger-tight.
10. Connect the air joint adapter (D) and the air pressure regulator (E).
11. Loosen the valve on the air pressure regulator, and apply the specified air pressure.
NOTE: If the rocker arm piston does not move after
applying air pressure, move the primary or
secondary rocker arm up and down manually by
rotating the crankshaft clockwise.

12. With the specified air pressure applied, move the
intake primary rocker arm (A) for the No. 1 cylinder.
The primary rocker arm and secondary rocker arm
(B) should move together.
 If the primary and the secondary rocker arm move together, go to step 13.
 If the intake secondary rocker arm do not move together, remove the primary and secondary
rocker arms as an assembly, and check that the
pistons in the primary and secondary rocker
arms move smoothly. If any rocker arm needs
replacing, replace the primary and secondary
rocker arms as an assembly, then retest.
13. Repeat step 12 on the remaining primary rocker arms with each piston at TDC. When all the primary
rocker arms pass the test, go to step 14.
14. Remove the air pressure regulator, the air joint adapter, the VTEC air stopper and VTEC air
adapters.
15. Tighten the camshaft holder mounting bolts to 22 N·m (2.2 kgf·m, 16 lbf·ft).
16. Tighten the sealing bolt to 20 N·m (2.0 kgf·m, 14 lbf·ft).
17. Install the cylinder head cover (see page 6-37).  VTEC air stopper 07ZAJ-PNAA200

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 6-36).
3. Set the No. 1 piston at TDC (see step 5 on page 6-18).
4. Move the secondary rocker arm (A) for No. 1 cylinder. The secondary rocker arm should move
independently of the mid rocker arm (B).
 If the secondary rocker arm moves freely, go to step 5.
 If the secondary rocker arm do not move independently, 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.
5. Repeat step 4 on the remaining secondary rocker arms with each piston at TDC. When all the
secondary rocker arms pass the test, go to step 6.
6. Check that the air pressure on the shop air compressor gauge indicates over 400 kPa
(4.0 kgf/cm , 57 psi).
7. Inspect the valve clearance (see page 6-14).
