Engine Oil
Inspection
2.
1.Park the vehicle on level ground, and turn off theengine. Allow the oil a few minutes to drain backinto the oil pan so the dipstick will show the actuallevet,
Make certain that the oil level indicated on the dip-stick is between the upper and lower marks. Insertthe dipstick carefully to avoid bending it.
lf the level has dropped close to the lower mark,add oil until it reaches the upper mark.

Replacement
CAUTION: Remove the drain plug caretuly white theengino is hot; the hot oil may cause scalding.
1. Warm up the engine.
2. Drain the engine oil.
WASHERR€place.ORAIN BOL4il N.m {4.5 kgtm,33 lbf.ft)Do not overtighten.
3. Reinstall the drain bolt with a new washer, and refill
with the recommended oil.
RequirementAPI Service Grade: Use "Energy
Conserving " SJ or "Energy
Conserving ll" SH grade oil. SAE
5W - 30 preferred: You can also
use an oil that bears the API
CERTIFICATION mark.
Capacity3.5 { (3.7 US qt,3.1 lmp qt)
at oil change.
3.8 / (4.0 US qt,3.3 lmp qr)
at oil change including filter.
4.6 { (4.9 US qt, 4.0 lmp qt)
after engine overhaul.
Change
Inlerval
Every 7,500 miles (12,000 km) or12 months (Normal conditions)
Every 3,750 miles (6,000 km) or 6months (Severe conditions).
NOTE: Under normal conditions, the oil filtershould be replaced at every other oil change. Undersevere conditions, the oil filter should be replacedat each oil change.

ll. Engine Controt Module (EcM)/Powertrain Control Module {PCM) Reset Procedure
Either of the following actions will reset the ECM/PCM.
. use the oBD ll scan tool or Honda PGM Tester to clear the ECM's/PCM's memory. (see the oBD ll scan tool or
Honda PGM Tester user's manuals for specific operating instructions )
. Turn the ignition switch oFF. Remove the BACK UP (RADIO) (7.5 A) fuse from the under-hood fuse/relay box for 10
seconos.
lll. Final Procedure {this procedure must be done after any troubleshooting)
1. Remove the SCS Service Connector if it is connected. lf the SCS service connector is connected. and there are no
DTCS stored in the ECM/PCM, the MIL will stay on when the ignition switch is turnsd oN (ll).
2. Do the ECM/PCM Reset Procedure.
3. Turn the ignition switch OFF
4. Disconnect the OBD ll scan tool orHonda PGM Tester from the Data Link Connector ( 16P)'

Troubleshooting
Troubleshooting Procedures (cont'd)
lf the inspection for a particular code requires voltage or resistance checks at the EcM/pcM connectors, remove the rightkick panel. Unbolt the EcM/PcM. and connect the backprobe sets and a digital multimeter as described below, check thesystem according to the procedure described for the appropriate code(s) listed on the following pages.
How to Us6 tho Backprobe S6ts
Backp.obo Adapto.
BACKPROBE SET
connect the backprobe adapters to the stacking patch cords. and connect the cords to a multimeter. Using the wire insula-tion as a guide for the contoured tip of the backprobe adapter, gently slide the tip into the connector from the wire sideuntil it comes in contact with the terminal end of the wire.

HO2S
Feedback
Loop Status
Loop status is indicated as "open" or "closed".
Closed: Based on the HO2S output, the ECM/pCM deter-mines the airlfuel ratio and controls the amount ofinjected fuel.
Open: ignoring HO2S output, the ECM/pCiM refers to sig,nals from the TP, MAP, and ECT sensors to control theamount of injected fuel.
At idle speed: closed
YES
Short Term
Fuel Trim
The airlfuel ratio correction coefficient for correcting theamount of injected fuel when HO2S feedback is in theclosed loop status. When the signal from the HO2S isweak, short term fuel trim gets higher, and the ECM/PCMincreases the amount of injected fuel. The airlfuel ratiogradually gets richer, causing a higher HO2S output.Consequently. the short term fuel trim is lowered. andthe ECM/PCM reduces the amount of injected fuel.This cycle keeps the airfuel ratio close to the stoichio-metric ratio when in closed looD status.
t:20y"
YES
Long Term
Fuel Trim
Long term fuel trim is computed from shon term fueltrim and indicates changes occuring in the fuel supplysystem over a long period.
lf long term fuel trim is higher than 1,00. the amount ofinjected fuel must be increased. lf it is lower than L00.the amount of injected fuel must be reduced.

Intake Air
Temperature
(IAT)
The IAT sensor converts intake air temperature into volt-age and signals the ECrU/PCM. When intake air tempera-ture is low, the internal resistance of the sensorincreases, and the voltage signal is higher.
With cold engine:
Same as ambient temper-
ature and ECTYES

Based on the accelerator pedal position, the openingangle of the throttle valve is indicateo.At idle speed:

lgnition timing is the ignition advance angle set by theECM/PCM. The ECM/PCM matches ignition timing to thedriving conditions.
