5. Run the engine for more than 3 minutes, then checkfor oil leakage.
6. Turn the ignition switch to LOCK (0).
7. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
8. Turn the ignition switch to ON (II).
9. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain
control module (PCM). If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
10. Select GAUGES in the BODY ELECTRICAL menu with the HDS.
11. Select ADJUSTMENT in the GAUGES menu with the HDS.
12. Select SERVICE REMINDER in the ADJUSTMENT menu with the HDS.
13. Select RESET in the SERVICE REMINDER menu with the HDS.
14. Select RESETTING THE ENGINE OIL LIFE with the HDS.
NOTE: If you changed the automatic transmission
fluid (ATF) at the same time with the engine oil,
select RESETTING THE ENGINE OIL LIFE AND ATF
with the HDS instead. Oil filter wrench 07HAA-PJ70101
1. Remove the oil filter with the oil filter wrench.
2. Inspect the filter to make sure the rubber seal is not stuck to the oil filter seating surface of the engine.
3. Inspect the threads (A) and rubber seal (B) on the new filter. Clean the seat on the engine block, then
apply a light coat of new engine oil to the filter
rubber seal. Use only filters with a built-in bypass
system.
4. Install the oil filter by hand.
5. After the rubber seal seats, tighten the oil filter clockwise with the oil filter wrench.

1. Remove the oil jet, and inspect it as follows. Make sure that a 1.1 mm (0.04 in.) diameter drillwill go through the nozzle hole (A) (1.2 mm
(0.05 in.) diameter).
 Insert the other end of a 1.1 mm (0.04 in.) drill into the oil intake (1.2 mm (0.05 in.) diameter).
Make sure the check ball (B) moves smoothly and
has a stroke of approximately 4.0 mm (0.16 in.).
 Check the oil jet operation with an air nozzle. It should take at least 200 kPa (2.0 kgf/cm , 28 psi)
to unseat the check ball.
NOTE: Replace the oil jet assembly if the nozzle is
damaged or bent.
2. Carefully install the oil jet. The mounting torque is critical.

TORQUE CURVE
 The i-VTEC system has a variable valve timing control (VTC) mechanism on the intake camshaft in addition to the
usual VTEC.
This system improves fuel efficiency and reduces exhaust emissions at all levels of engine speed, vehicle speed,
and engine load.
 The VTEC system changes the valve lift and timing by using more than one cam profile.
 The VTC system changes the phase of the intake camshaft via oil pressure. It changes the intake valve timing continuously.
Driving Condition VTC Control Description
Light-load Base Position For stable combustion, the cam angle is retarded, and reduces the entry of exhaust gas into the cylinder.
Medium/high-load Advance Control Cam phase angle is controlled to optimize valve timing, improving fuel efficiency and reducing
emissions.
High speed Advance-Base Position To reduce pumping loss, the intake valve is closed quickly. This gives the air/fuel mixture a charging
effect that helps to maximize engine power.

 The VTC system makes continuous intake valve timing changes based on operating conditions.
 Intake valve timing is optimized to allow the engine to produce maximum power.
 Cam angle is advanced to obtain the EGR effect and reduce pumping loss. The intake valve is closed quickly to
reduce the entry of the air/fuel mixture into the intake port and improve the charging effect.
 The system reduces the cam advance at idle, stabilizes combustion, and reduces engine speed.
 If a malfunction occurs, the VTC system control is disabled and the valve timing is fixed at the fully retarded position.
 The VTEC system changes the cam profile to correspond to the engine speed. It maximizes torque at low engine speed and output at high engine speed.
 The low lift cam is used at low engine speeds, and the high lift cam is used at high engine speeds.

4. Install a locknut plate (A) and a new locknut (B).
5. Using the special tool, tighten the new locknut (A) to the specified torque.
NOTE: After tightening, make sure the marks are still aligned.
 After installation, check the base gasket, visually or by hand, to make sure it is not pinched. 6. Connect the fuel tank unit 4P connector, then
connect the quick-connect fitting.
7. Reconnect the negative cable to the battery, and turn the ignition switch to ON (II) (but do not
operate the starter motor). The fuel pump will run
for about 2 seconds, and fuel pressure will rise.
Repeat this two or three times, then check that
there is no leakage in the fuel supply system.
8. Install the access panel (A) to the floor.
9. Install the rear floor upper cross-member (A).
10. Install the rear seat cushion (see page 20-131).
11. Install the fuel fill cap.
