P2067
PPowertrainFuel Level Sensor B Circuit Low
What does this code mean?
Severity : LowP2067 indicates low voltage on the fuel level sensor B circuit. Some tanks, especially saddle shaped ones, use two sensors to measure the level on each side. The module or instrument cluster receives a signal that is too low, often caused by a short to ground or a faulty sensor.
Symptoms
- Check engine light on.
- Incorrect fuel gauge, often stuck at empty.
- Unjustified low fuel warning.
- Implausible range display.
Possible causes
- Faulty fuel level sensor B or worn track.
- Wiring shorted to ground.
- Corroded tank module connector.
- Stuck or damaged float.
- Instrument cluster or module fault, which is rare.
Diagnosis and repair
- Inspect the tank module connector and wiring.
- Read sensor B value in live data.
- Measure sensor resistance with a multimeter at different levels.
- Check the signal wire for a short to ground.
- Replace the sensor or repair the wiring, then clear the code.
