What the code means
The Powertrain Control Module (PCM) detects that the fuel level sensor's input is outside expected range. This could stem from a faulty sensor, damaged wiring, or a poor electrical connection. The issue affects the accuracy of the fuel gauge and may trigger the check-engine light.
Common causes
- Faulty fuel level sensor
- Damaged wiring or corroded connectors
- Poor ground connection
- Faulty instrument cluster gauge
- Low fuel pressure affecting sensor readings
What shows on a live scan
During a live data scan, the PCM monitors the fuel level sensor signal. Typical PIDs observed include:
- Fuel Level Input (PID 01 2F)
- Fuel Level Sensor Circuit High/Low (PID 01 2E)
- Fuel Level Sensor Reference Voltage (PID 01 2D) These values vary by vehicle model and year. A reading outside the manufacturer's specified range confirms the issue.
DIY-safe check
Inspect the fuel level sensor wiring and connectors for damage, corrosion, or loose pins. Ensure the ground connection is secure. If wiring appears intact, the sensor may need replacement.
When to consult a specialist
If the wiring and connections are in good condition, or if the issue persists after inspection, consult a specialist. Complex electrical diagnostics or sensor replacement may be required.
