Fuel Gauge Pointer Fluctuates, Indicator Wrong Value or VariesNKS0006A
1. CHECK FUEL GAUGE FLUCTUATION
Test drive vehicle to see if gauge fluctuates only during driving or at the instant of stopping.
Does the indication value vary only during driving or at the instant of stopping?
YES >> The pointer fluctuation may be caused by fuel level change in the fuel tank. Condition is normal.
NO >> Ask the customer about the situation when the symptom occurs in detail, and perform the trouble
diagnosis.
Fuel Gauge Does Not Move to FULL PositionNKS0006B
1. QUESTION 1
Does it take a long time for the pointer to move to FULL position?
YES >> GO TO 2.
NO >> GO TO 3.
2. QUESTION 2
Was the vehicle fueled with the ignition switch ON?
YES >> Be sure to fuel the vehicle with the ignition switch OFF. Otherwise, it will take a long time to move
to FULL position because of the characteristic of the fuel gauge.
NO >> GO TO 3.
3. QUESTION 3
Is the vehicle parked on an incline?
YES >> Check the fuel level indication with vehicle on a level surface.
NO >> GO TO 4.
4. QUESTION 4
During driving, does the fuel gauge pointer move gradually toward EMPTY position?
YES >> Check the fuel level sensor unit. Refer to DI-23, "FUEL LEVEL SENSOR UNIT" .
NO >> The float arm may interfere or bind with any of the components in the fuel tank.

Revision: 2006 November2007 350Z
TRIPLE METERSPFP:24845
System DescriptionNKS0006F
TRIPLE METER
Oil pressure gauge and voltmeter are controlled by the triple
meter.
Trip computer is controlled by the signals from the unified meter
and A/C amp.
Triple meter operation can be checked with self-diagnosis mode
of combination meter.
UNIFIED METER AND A/C AMP.
Refer to DI-45, "TRIPLE METER CONTROL FUNCTION" in “UNIFIED METER AND A/C AMP”.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
through 10A fuse [No. 19, located in the fuse block (J/B)]
to triple meter terminal 2.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 14, located in the fuse block (J/B)]
to triple meter terminal 3.
Ground is supplied
to triple meter terminal 1
through grounds M30 and M66.
VOLTMETER
When ignition switch is turned to the ON position, the voltmeter indicates the battery voltage.
OIL PRESSURE GAUGE
With the ignition switch in the ON or START position, power is supplied
through triple meter terminal 9
to oil pressure sensor terminal 1.
Ground is supplied
to triple meter terminal 7
through oil pressure sensor terminal 3.
And triple meter reads oil pressure signal from oil pressure sensor
from oil pressure sensor terminal 2
to triple meter terminal 8.
NOTE:
Triple meter judges an oil pressure condition by oil pressure signal, and transmits oil pressure warning
lamp signal to combination meter through unified meter and A/C amp. with communication line.
Oil pressure gauge is not designed to indicate the low oil level. Use the oil level gauge to check the oil
level.

TRIP COMPUTER
Function
When the ignition switch is turned ON, the display scrolls all the modes. And then shows the mode chosen
before the ignition switch is turned OFF.
Trip computer is operated by the trip computer switch.
Trip computer receives a switch signal from combination meter
through the unified meter and A/C amp. with communication
line.
The mode of the trip computer is the following.
Vehicle speed
Ambient air temperature
DTE (distance to empty)
Average fuel consumption
Average vehicle speed
Trip time
Trip distance
St op watc h
Shift-up indicator setting mode
How to Change/ Reset the Displayed Mode
The displayed mode can be selected in the following order by momentarily pressing the trip computer
mode switch.
–Vehicle speed → Ambient air temperature → DTE → Average fuel consumption and average vehicle
speed → Trip time and trip distance → Stopwatch → Shift-up indicator setting
Holding the trip computer setting switch for more than 1 second resets the displayed mode (Average fuel
consumption, average vehicle speed, trip time, trip distance or stopwatch).
NOTE:
When the ambient air temperature warning, the tire pressure warning, and the DTE warning, match warning
conditions at the same time, the display automatically displays the ambient air temperature warning.
Vehicle Speed
Trip computer receives vehicle speed signal from combination meter through the unified meter and A/C
amp. with communication line.
Trip computer displays the vehicle speed according to vehicle speed signal.
Ambient Air Temperature
Unified meter and A/C amp. reads ambient air temperature signal from ambient air temperature sensor.
Signal is supplied
–from unified meter and A/C amp. terminal 39
–through ambient sensor terminal 1 and 2
–to unified meter and A/C amp. terminal 49.
Trip computer receives ambient air temperature signal from the unified meter and A/C amp. with commu-
nication line.
Trip computer displays ambient air temperature according to ambient air temperature signal.
NOTE:
Indication range is between −30 and 55 °C (−22 and 131 °F).
When ambient air temperature is less than −30 °C (−22 °F) or more than 55 °C (131 °F), the display
shows “--”.
When ambient air temperature is less than 3 °C (37 °F) continuously, the display shows “ICY” as warning.
At more than 4 °C (39 °F) the display stops showing “ICY”.
