Self-Diagnosis Mode of Combination MeterINFOID:0000000005395014
SELF-DIAGNOSIS MODE FUNCTION
• Self-diagnosis can check for continuity between meter control circuit and each meter (speedometer, tachom- eter and fuel gauge).
• Self-diagnosis can check for odo/trip meter and A/T indi cator (with A/T) or CVT indicator (with CVT) seg-
ment, low-fuel level warning lamp, low water temperature indicator lamp, and high water temperature warn-
ing lamp.
OPERATION PROCEDURE
1. Turn the ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”. NOTE:

P0116 ECT SENSOR
DescriptionINFOID:0000000005398334
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor
modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the change in temperature. The electrical resistance of the ther-
mistor decreases as temperature increases.

*: These data are reference values and are measured between ECM terminal 38
(Engine coolant temperature sensor) and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output vo ltage. Doing so may result in damage to the ECM's transis-
tor. Use a ground other than ECM terminals, such as the ground.
DTC LogicINFOID:0000000005398335
DTC DETECTION LOGIC
NOTE:
If DTC P0116 is displayed with P0117 or P0118, first perform the trouble diagnosis for DTC P0117,
P0118. Refer to EC-161, "
DTC Logic".
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC confirmation procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and warm it up to normal operating temperature.
2. Rev engine up to 2,000 rpm for more than 10 minutes.
3. Move the vehicle to a cool place, then stop engine and turn ignition switch OFF.
4. Check resistance between “fuel level s ensor unit and fuel pump” terminals 4 and 5.

5. Soak the vehicle until the resistance between “fuel level sensor unit and fuel pump” terminals 4 and 5
becomes 0.5 k Ω higher than the value measured before soaking.
CAUTION:
Never turn ignition switch ON during the soaking time.
NOTE:
Soak time changes depending on ambient ai r temperature. It may take several hours.
6. Start engine and let it idle for 20 minutes.
7. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> EC-160, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000005398336
1.CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connections E15, 24. Refer to EC-119, "
Ground Inspection".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK ENGINE COOLANT TEMPERATURE SENSOR
Refer to EC-160, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace engine coolant temperature sensor.
3.CHECK INTERMITTENT INCIDENT
Refer to EC-114, "
Diagnosis Procedure".
>> INSPECTION END
Component InspectionINFOID:0000000005398337
1.CHECK ENGINE COOLANT TEMPERATURE SENSOR
1. Turn ignition switch OFF.
2. Disconnect engine coolant temperature sensor harness connector.
3. Remove engine coolant temperature sensor.
4. Check resistance between engine coolant temperature sensor terminals by heating with hot water as shown in the figure.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace engine coolant temperature sensor.
