Engine Compression Inspection

NOTE: On the 2005-2006 models: After this inspection,
you must reset the engine control module (ECM)/
powertrain control module (PCM), otherwise ECM/PCM
will continue to stop the injectors from functioning.
Select ECM/PCM reset using the Honda Diagnostic
System (HDS) (see page 11-4).

1. Warm up the engine to normal operating

temperature (cooling fan comes on).

2. Turn the ignition switch OFF.

3. 2002-2004 models: Remove the No. 17 (15 A) fuse

from the under-dash fuse/relay box.
2005-2006 models: Connect the HDS to the data link
connector (DLC) (see step 2 on page 11-3). Turn the
ignition switch ON (II), then select PGM-FI,
INSPECTION, then All INJECTORS OFF function on
the HDS.

4. Remove the four ignition coils (see page 4-26).

5. Remove the four spark plugs.

6. Attach the compression gauge to the spark plug

hole.

7. Open the throttle fully, then crank the engine with

the starter motor and measure the compression.

8. Measure the compression on the remaining

cylinders.

9. If the compression is not within specifications,

check the following items, then remeasure the
compression.

• Damaged or worn valves and seats
• Damaged cylinder head gasket
• Damaged or worn piston rings
• Damaged or worn piston and cylinder bore

10. Remove the compression gauge from the spark

plug hole.

11. Install the four spark plugs.

12. Install the four ignition coils (see page 4-26).

13. 2002-2004 models: Install the No. 17 (15 A) fuse

from the under-dash fuse/relay box.
2005-2006 models: Select ECM/PCM reset
(see page 11-4) to stop the ALL INJECTORS OFF
function on the HDS.

07ZAJ-PNAA200

C
07ZAJ-PNAA100

• Air pressure regulator 07AAJ-PNAA100
• VTEC air adapter 07ZAJ-PNAA100
• 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 OFF.

2. Remove the cylinder head cover (see page 6-28).

3. Set the No. 1 piston at top dead center (TDC) (see

step 1 on page 6-14).

4. Verify that the intake primary rocker arm (A) moves

independently of the intake secondary rocker arm
(B).

• If the intake primary rocker arm does not move,

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, and test.

• If the intake primary rocker arm moves freely, go

to step 4.

5. Repeat step 3 on the remaining intake primary

rocker arms with each piston at TDC. When all the
primary rocker arms pass the test, go to step 5.

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 6-11).

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 air pressure

regulator (E).
