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.

VTC Actuator Inspection
A B
1. Remove the cam chain (see page 6-18).
2. Loosen the rocker arm adjusting screws: K20Z2 engine (see step 2 on page 6-43)
 K20Z3 engine (see step 2 on page 6-44)
3. Remove the camshaft holder:  K20Z2 engine (see step 3 on page 6-43)
 K20Z3 engine (see step 3 on page 6-44)
4. Remove the intake camshaft.
5. Check that the variable valve timing control (VTC) actuator is locked by turning the VTC actuator
counterclockwise. If not locked, turn the VTC
actuator clockwise until it stops, then recheck it. If it
is still not locked, replace the VTC actuator.
6. Seal the advance holes (A) and the retard holes (B) in the No. 1 camshaft journal with tape.
7. Punch a hole in the tape over one of the advance holes.
8. Apply air to the advance hole to release the lock. 9. Check that the VTC actuator moves smoothly. If the
VTC actuator does not move smoothly, replace the
VTC actuator.
10. Remove the tape and adhesive residue from the No. 1 camshaft journal.
11. Make sure the punch marks on the VTC actuator and the exhaust camshaft sprocket are facing up,
then set the camshafts in the rocker shaft holder:
 K20Z2 engine (see step 6 on page 6-61)
 K20Z3 engine (see step 6 on page 6-62)
12. Set the camshaft holders and cam chain guide B in place:
 K20Z2 engine (see step 7 on page 6-61)
 K20Z3 engine (see step 7 on page 6-62)
13. Tighten the camshaft holder bolts to the specified torque:
 K20Z2 engine (see step 8 on page 6-61)
 K20Z3 engine (see step 8 on page 6-62)
14. Hold the camshaft, and turn the VTC actuator clockwise until you hear it click. Make sure to lock
the VTC actuator by turning it.
15. Install the cam chain (see page 6-21).
16. Adjust the valve clearance:  K20Z2 engine (see page 6-12)
 K20Z3 engine (see page 6-14)

NOTE: Connector the Honda Diagnostic System (HDS)
to the data link connector (DLC) (see step 2 on page
11-3), and monitor the engine coolant temperature
(ECT) sensor 1 with the HDS. Adjust the valve clearance
only when the engine coolant temperature is less than
38 °C (100 °F). 1. Remove the cylinder head cover (see page 6-36).
2. Set the No. 1 piston at top dead center (TDC). The punch mark (A) on the variable valve timing control
(VTC) actuator and the punch mark (B) on the
exhaust camshaft sprocket should be at the top.
Align the TDC marks (C) on the VTC actuator and
the exhaust camshaft sprocket. 3. Select the correct feeler gauge for the valve
clearance you are going to check.
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.

Camshaft lock pin set 07AAB-RWCA120
NOTE: Keep the cam chain away from magnetic fields.
 Before doing this procedure, check that the variable valve timing control (VTC) actuator is locked by
turning the VTC actuator counterclockwise. If not
locked, turn the VTC actuator clockwise until it stops,
then recheck it. If it is still not locked, replace the VTC
actuator.
1. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with
the pointer (B) on the engine block.
2. Set the camshafts to TDC. The punch mark (A) on the VTC actuator and the punch mark (B) on the
exhaust camshaft sprocket should be at the top.
Align the TDC marks (C) on the VTC actuator and
the exhaust camshaft sprocket. 3. To hold the intake camshaft, insert a camshaft lock
pin (07AAB-RWCA120) (A) into the maintenance
hole in camshaft position (CMP) pulse plate A (B)
and through No. 5 rocker shaft holder (C).
4. To hold the exhaust camshaft, insert a camshaft lock pin (A) into the maintenance hole in CMP pulse
plate B (D) and through No. 5 rocker shaft holder
(C).
