What is SPN 102 FMI 17
- SPN 102: Refers to a fault with the fuel level sensor, indicating that the fuel level reading is either too high or too low.
- FMI 17: Indicates that the signal from the sensor is out of range or invalid, meaning the ECM is not receiving proper data from the sensor.
Together, SPN 102 FMI 17 signals a problem with the fuel level sensor, which could lead to inaccurate fuel readings and potentially affect fuel management and performance.
Why It Happened
This fault code is caused by:
- A malfunctioning or damaged fuel level sensor.
- Wiring issues or loose connections between the sensor and ECM.
- Contamination in the fuel tank affecting sensor readings.
- A software issue in the ECM affecting the sensor’s data.
How to Resolve It
To resolve SPN 102 FMI 17:
- Inspect the fuel level sensor for faults and replace if necessary.
- Check the wiring and connections for damage or corrosion.
- Clean the fuel tank to ensure proper sensor function.
- After repairs, clear the fault code and restart the engine.
How to Avoid Before It Happens
To prevent SPN 102 FMI 17:
- Regularly inspect the fuel level sensor and wiring.
- Keep the fuel tank clean and free from contaminants.
- Use Clue to monitor fuel system data and receive early alerts on irregular readings.
