P0460 FUEL LEVEL SENSOR
VR38
P0460
Description
The fuel level sensor is mounted in the fuel level sensor unit.
The sensor detects a fuel level in the fuel tank and transmits a signal to the combination meter. The combination meter sends the fuel level sensor signal to the ECM through the CAN communication line.
It consists of two parts, one is mechanical float and the other is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.
DTC Logic
DTC DETECTION LOGICNOTE：
-
If DTC P0460 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
-
If DTC P0460 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607.
Refer to DTC Logic (GT-R certified NISSAN dealer).
When the vehicle is parked, naturally the fuel level in the fuel tank is naturally stable. It means that output signal of the fuel level sensor does not change. If ECM senses sloshing signal from the sensor, fuel level sensor malfunction is detected.
| DTC No. | Trouble diagnosis name | DTC detecting condition | Possible cause |
| P0460 | Fuel level sensor circuit noise | Even though the vehicle is parked, a signal being varied is sent from the fuel level sensor to ECM. |
