DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 2.
2.CHECK ENGINE COOLANT TEMPERATURE SENSOR FUNCTION
With CONSULT
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
3. Check that “COOLAN TEMP/S” is above 10 °C (50 °F).
With GST
Follow the procedure “With CONSULT” above.
Is it above 5
°C (41°F)?
YES >> INSPECTION END
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
1. Start engine and run it for 65 minutes at idle speed.
2. Check 1st tip DTC.
If “COOLAN TEMP/S” indicatio n increases to more than 10°C (50 °F) within 65 minutes, stop engine
because the test resu lt will be OK.
CAUTION:
Be careful not to overheat engine.
With GST
Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected?

To judge malfunctions, this diagnosis measures response
time of the A/F signal computed by ECM from the A/
F sensor 1 signal. The time is compensated by engi ne operating (speed and load), fuel feedback control con-
stant, and the A/F sensor 1 temperature index. Judgment is based on whether the compensated time (the A/F
signal cycling time index) is inordinately long or not.
DTC CONFIRMATION PROCEDURE

NO >> INSPECTION END
6.CHECK AIR-FUEL RATIO SELF-LEARNING VALUE
With GST
1. Start engine and warm it up to normal operating temperature.
2. Select Service $01 with GST.
3. Calculate the total value of “Short term fuel trim” and “Long term fuel trim” indications.
Is the total percentage within
±15%?
YES >> GO TO 8.
NO >> GO TO 7.
7.DETECT MALFUNCTIONING PART
Check the following.
• Intake air leaks
• Exhaust gas leaks
• Incorrect fuel pressure
• Lack of fuel
• Fuel injector
• Incorrect PCV hose connection
• PCV valve
• Mass air flow sensor
>> Repair or replace malfunctioning part.
8.PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
5. Let engine idle for 1 minute.

DTC No. CONSULT screen terms
(Trouble diagnosis content) DTC detecting condition Possible cause
P0196 EOT SENSOR
(Engine oil temperature sensor
range/performance) A)
Rationally incorrect voltage from the
sensor is sent to ECM, compared with
the voltage signals from EOT sensor
and intake air temperature sensor. • Harness or connectors
(EOT sensor circuit is open or short-
ed)
• EOT sensor
B) The comparison result of signals trans-
mitted to ECM from each temperature
sensor (IAT sensor, ECT sensor, FTT
sensor, and EOT sensor) shows that the
signal voltage of the EOT sensor is high-
er/lower than that of other temperature
sensors when the engine is started with
its cold state. • Harness or connectors
(High or low resistance in the EOT
sensor circuit)
• EOT sensor
