2.CHECK DTC WITH “COMBINATION METER”
Refer to CONSULT-III Function (METER/M&A).
Is the inspection result normal?
YES>>GO TO 3.
NO>>Go to Component Function Check.
3.CHECK FUEL TANK TEMPERATURE SENSOR POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.
2. Disconnect “fuel level sensor unit and fuel pump” harness connector.
3. Turn ignition switch ON.
4. Check the voltage between “fuel level sensor unit and fuel pump (main)” harness connector and ground.

   Fuel level sensor unit and fuel pump (main) | Ground | Voltage (V)
   Connector | Terminal
   B225 | 1 | Ground | Approx. 5

Is the inspection result normal?
YES>>GO TO 5.
NO>>GO TO 4.
4.DETECT MALFUNCTIONING PART
Check the following.

>>Repair open circuit, short to ground or short to power in harness or connector.
5.CHECK FUEL TANK TEMPERATURE SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

1. Turn ignition switch OFF.
2. Disconnect “combination meter” harness connector.
3. Check the continuity between “fuel level sensor unit and fuel pump (main)” harness connector and “combination meter” harness connector.

   Fuel level sensor unit and fuel pump (main) | Combination meter | Continuity
   Connector | Terminal | Connector | Terminal
   B225 | 3 | M53 | 18 | Existed

4. Also check harness for short to ground and short to power.

YES>>GO TO 7.
NO>>GO TO 6.
6.DETECT MALFUNCTIONING PART
Check the following.

- Harness connectors B201, M117
- Harness for open or short between “fuel level sensor unit and fuel pump (main)” and “combination meter”

>>Repair open circuit, short to ground or short to power in harness or connector.
7.CHECK FUEL TANK TEMPERATURE SENSOR
Refer to Component Inspection (GT-R certified NISSAN dealer).
Is the inspection result normal?
YES>>GO TO 8.
NO>>Replace “fuel level sensor unit and fuel pump (main)”.
8.CHECK INTERMITTENT INCIDENT
Refer to Intermittent Incident.
