NOTE: If the oil pressure warning indicator stays on
with the engine running, check the engine oil l
evel. If
the oil level is correct do the following test:
1. With the engine stopped, remove the oil pressure switch (see page 8-9), then install an oil pressure
gauge (A).
2. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem
before continuing.
3. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should
be:
4. If the oil pressure is out of specifications, inspect these items:
 Blocking of oil filter (see page 8-11).
 Blocking of oil screen.
 Inspect the oil pressure relief valve (see page 8-15).
 Inspect the oil pump (see page 8-17). 1. Warm up the engine.
2. Remove the drain bolt (A), and drain the engine oil.
3. Reinstall the drain bolt with a new washer (B).
4. Refill the engine with the recommended oil
(see page 3-2).
Do not overtighten.

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.

6. If four numbers or marks (1 to 4 or to )
are printed around the outside of the filter, use the
following procedure to tighten the filter.
 Spin the filter on until its seal lightly seats against the engine block, and note which number or
mark is at the bottom.
 Tighten the filter by turning it clockwise three numbers or marks from the one you noted. For
example, if number 2 is at the bottom when the
seal is seated, tighten the filter until the number 1
comes around the bottom.
