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.

6. Tighten the locknut to the specified torque, and recheck the clearance. Repeat the adjustment if
necessary. 7. Rotate the crankshaft 180 ° clockwise (camshaft
pulley turns 90 °).
8. Check and, if necessary, adjust the valve clearance on the No. 3 cylinder.
9. Rotate the crankshaft 180 ° clockwise (camshaft pulley turns 90 °).

4. Insert the feeler gauge (A) between the adjusting screw (B) and the end of the valve stem, then slide
it back and forth, you should feel a slight amount of
drag. 5. If you feel too much or too little drag, loosen the

1. Clean the crankshaft pulley (A), crankshaft (B), bolt(C), and washer (D). Lubricate with new engine oil
as shown.
2. Install the crankshaft pulley, and hold the pulley with the holder handle (A) and holder attachment
(B). 3. Tighten the bolt to 49 N·m (5.0 kgf·m, 36 lbf·ft) with
a torque wrench and the socket, 19 mm (C). Do not
use an impact wrench. If the pulley bolt or
crankshaft are new, tighten the bolt to 177 N·m
(18.0 kgf·m, 130 lbf·ft), then remove the bolt and
tighten it to 49 N·m (5.0 kgf·m, 36 lbf·ft).
4. Mark the bolt head (A) and the crankshaft pulley (B) as shown, then tighten the bolt an additional 90 °
(The mark on the bolt head line up with the mark on
the crankshaft pulley).
5. Install the drive belt (see page 4-31).
6. Install the splash shield (see step 40 on page 5-20).
7. Install the right front wheels.
