P0461 00

Fuel Level Sensor Circuit, Preformance Problem







Fault symptom
- D.T.E out or order.

On-board diagnosis

Type of diagnosis:
- Continuous

Enable criteria:

General conditions for this DTC
- Battery voltage must be between 11 - 16 V.
- Engine running.

- NONE of the following DTCs must be detected:
- P0462, P0463

Test 1
- Fuel level below 55 litres.

Test 2
- Fuel level over 55 litres.

Fault criteria:

Test 1
- The diagnosis calculates the fuel consumption over a distance of 35 km. A DTC is generated if 5 measurements in succession differ more than 0.5 litres from each other.

Test 2
- The diagnosis calculates the fuel consumption over a distance of 70 km. A DTC is generated if 5 measurements in succession differ more than 0.5 litres from each other.

Dependent:
- None

System reaction to a fault:
- The control module uses a substitute value of 40 litres when fault is detected.

Fault handling:
- Type III without Check Engine.
- (See section Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness
- Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.
