Fuel Level Sensor Circuit, Performance Problem
Fault symptom
D.T.E out or order.
On-board diagnosis
Type of diagnosis:
Enable criteria:
| General conditions for this DTC |
| • | Battery voltage must be between 11 - 16 V. |
| NONE of the following DTCs must be detected: |
| • | Fuel level below 55 litres. |
| • | Fuel level over 55 litres. |
Fault criteria:
| 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. |
| 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:
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.
