2. Check “COOLANT TEMP/S” value.

With GST

Follow the procedure “With CONSULT” above.
“COOLANT TEMP/S” less than 60

C (140

F)?

YES

>> INSPECTION END

>> GO TO 5.

PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-II

With CONSULT

FTT SENSOR
(Fuel temperature sensor a cir-
cuit range/performance)

Rationally incorrect voltage from the
sensor is sent to ECM, compared with
the voltage signals from ECT sensor
and intake air temperature sensor.

• Harness or connectors

(The FTT sensor circuit is open or
shorted)

• FTT sensor

The comparison result of signals trans-
mitted to ECM from each temperature
sensor (IAT sensor, ECT sensor, EOT
sensor, and FTT sensor) shows that
the voltage signal of the FTT sensor is
higher/lower than that of other temper-
ature sensors when the engine is start-
ed with its cold state.

• Harness or connectors

(High or low resistance in the FTT
sensor circuit)

• FTT sensor

PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-

dure 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.

TESTING CONDITION:

•

Before performing the following procedure, do not add fuel.

•

Before performing the following procedure, check that fuel level is between 1/4 and 4/4.

•

Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

>> GO TO 8.

PERFORM DTC CONFIRMATION PROCEDURE B

1. Move the vehicle to a cool place.

NOTE:

−

C (14

F) and 35

C (95

F).

2. Turn ignition switch OFF and leave the vehicle for 12 hours.

CAUTION:

Never turn ignition switch ON during this procedure.

NOTE:

The vehicle must be cooled with the hood open.

3. Start engine and let it idle for 5 minutes or more.

CAUTION:

Never turn ignition switch OFF during idling.

4. Check 1st trip DTC.
Is 1st trip DTC detected?

YES
