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.

1.CHECK FUEL TANK TEMPERATURE SENSOR
Subwoofer
Description
The AV control unit sends audio signals to the BOSE speaker amp. The BOSE
speaker amp. amplifies the
audio signals before sending them to the subwoofers using the audio signal
circuits.
Diagnosis Procedure
1.CONNECTOR CHECK
Check the AV control unit, BOSE speaker amp. and subwo ...
Towing recommended by NISSAN
CAUTION
Never tow CVT models with the front
wheels on the ground or 4 wheels on
the ground (forward or backward), as
this may cause serious and expensive
damage to the transmission. If it is necessary
to tow the vehicle with the rear
wheels raised always use towing dollies
under the ...
