Description
The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank. The sensor modifies a voltage signal from the ECM. The modified signal returns to the ECM as the fuel temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
<Reference data>
*: These data are reference values and are measured between ECM terminals 95 (Fuel tank temperature sensor) and 104 (sensor ground).

3.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-I
4.CHECK ENGINE COOLANT TEMPERATURE
With CONSULT
With GST
Follow the procedure "With CONSULT" above.
5.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-II
With CONSULT
With GST
Follow the procedure "With CONSULT" above.
6.PERFORM COMPONENT FUNCTION CHECK (FOR MALFUNCTION B)
Perform component function check. Refer to EC-271, "Component Function Check".
NOTE: Use the component function check to check the overall function of the FTT sensor circuit. During this check, a 1st trip DTC might not be confirmed.
7.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
8.PERFORM DTC CONFIRMATION PROCEDURE B
NOTE: The vehicle must be cooled with the food open.
