4) Screw new filter on oil filter stand by hand until the filter O-ring contacts mounting surface.
CAUTION!
To tighten oil filter prop erly, it is important to
accurately identify the position at which filter
O-ring first contacts mounting surface.

5) Tighten the filter (1) 3/4 tu rn from the point of contact
with the mounting surface using an oil filter wrench
(2).
Tightening torque
Oil filter (b): 14 N·m (1 .4 kgf-m, 10.5 lb-ft) for
reference
6) Replenish oil until oil leve l is brought to FULL level
mark on dipstick (oil pan and oil filter capacity). The
filler inlet is at the top of the cylinder head cover. It is
recommended to use engine oil of SG, SH, SJ, SL or
SM grade. Select the appropriate oil viscosity
according to the proper engine oil viscosity chart [A].
NOTE
Engine oil capacity is specified as the
following.
However, note that the amount of oil required
when actually changing oil may somewhat
differ from the data depending on various
conditions (temperature, viscosity, etc.).

Engine oil specification
Oil pan capacity: About 3.7 liters (7.8 / 6.5 US /
lmp pt.)
Oil filter capacity: About 0.2 liter (0.4 / 0.3 US /
lmp pt.)
Others: About 0.3 liter (0 .6 / 0.5 US / lmp pt.)
Total: About 4.2 liters (8.9 / 7.4 US / lmp pt.) 7) Check oil filter and drain plug for oil leakage.
8) Start engine and run it for 3 minutes. Stop it and wait
another 5 minutes before checking oil level. Add oil,
as necessary, to bring oil le vel to FULL level mark (1)
on dipstick.
Engine Coolant ChangeS7RS0B0206005
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if cap is
taken off too soon.

CAUTION!
When changing engine coolant, use mixture
of 50% specified water and 50% ANTIFREEZE
/ ANTICORROSION COOLANT for the
purpose of corrosion protection and
lubrication.

Change engine coolant with new one referring to
“Cooling System Flush and Refill in Section 1F”.

DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out by 2 persons, a driver and a tester, on a level road.

NOTE
Check to make sure that the following conditions are satisfied when using this “DTC Confirmation
Procedure”.
• Intake air temperature at engine start: –10 °C (14 °F) to 80 °C (176 °F)
• Intake air temperature: –10 °C (14 °F) to 70 °C (158 °F)
• Engine coolant temperature: 70 °C (158 °F) to 150 °C (302 °F)
• Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)

1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and warm up to normal operating temperature. (ECT approx. 90 – 95 °C, 194 – 203 °F)
4) Drive vehicle with engine speed: more than 2500 rpm for 1 min.
5) Increase vehicle speed to 80 km/h (45 mile/h) at 5th gear or D range.
6) Release accelerator pedal to decrease vehicle speed to 40 km/h (25 mile/h).
7) Stop vehicle and run it idle for 1 min.
8) Check DTC and pending DTC.
DTC Troubleshooting
NOTE
• When measuring circuit voltage, resistance and/ or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors re ferring to “Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.

Step Action YesNo
1 Was “Engine and Emission Control System Check”
performed? Go to Step 2.
Go to “Engine and
Emission Control
System Check”.
2 Visual inspection
Check MAF sensor and air intake system for:
• Objects which block measuring duct and resistor of MAF
sensor.
• Other air flow which does not pass the MAF sensor.
Are they in good condition? Go to Step 3.
Repair or replace.
3 MAF sensor and its circuit check
1) With ignition switch turned OFF, connect scan tool.
2) Start engine and warm up to normal operation
temperature.

2 DTC check
1) With ignition switch turned OFF, install scan tool to DLC.
2) Turn ON ignition switch and check DTC with scan tool.
Is DTC P0118 displayed? Go to “DTC P0118:
Engine Coolant
Temperature Circuit
High”.
Go to Step 3.
3 Engine coolant temp. check
1) Turn ON ignition switch and check engine coolant temp.
displayed on scan tool.
2) Warm up engine to normal operating temp. and check engine coolant temp. displayed on scan tool.
Does engine coolant te mp. vary more than 1
°C (1 °F) and
rise higher than 70
°C (158 °F)? Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
Go to Step 4.
4 Thermostat check
Is there a symptom due to thermostat remaining open (it
takes a long time before vehicle heater becomes effective or
before engine is warmed to normal operating temp., etc.)? Check thermostat
referring to “Thermostat
Inspection in Section
1F”.
Go to Step 5.

• Intake air temperature: –10 °C (14 °F) to 70 °C (158 °F)
• Engine Coolant temperature: 70 °C (158 °F) to 150 °C (302 ° F)
• Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)

1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and warm up to normal operating temperature.
4) Drive vehicle at 40 mph (60 km/h) or higher. (engine speed: 2500 – 3000 r/min.)
5) Keep above vehicle speed for 6 min. or more. (Throt tle valve opening is kept constant in this step.)
6) Release accelerator pedal and with engine brake applied, keep vehicle coasting (with fuel cut for 3 sec. or more)
and then stop vehicle.
7) Check if DTC and pending DTC exist by using scan tool. If not, check if oxygen sensor monitoring test has been
completed by using scan tool. If not in both of above c hecks (i.e., no DTC and pending DTC and oxygen sensor
monitoring test not completed), check vehicle cond ition (environmental) and repeat Step 3) through 6).
DTC Troubleshooting
NOTE
• When measuring circuit voltage, resistance and/ or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors re ferring to “Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.
