P2067: A low fuel-level sensor B circuit is not a direct empty-tank measurement

P2067 is Ford's fuel level sensor B circuit-low result. The electrical category should remain separate from actual fuel quantity: an invalid low input is not reliable proof that the tank or one tank chamber is empty.

Identify which electrical input failed

The source lists sensor A and B low/high codes separately and gives a 30-second duration for electrical malfunctions. It also provides distinct diagnostics for noisy signals and readings that remain stuck despite fuel consumption. Those checks evaluate different behaviors and should not be used interchangeably.

Preserve the full code and the B-channel input state rather than relying only on the dashboard's combined fuel display. The summary does not establish how multiple sender inputs are combined on every vehicle.

Do not transfer the adjacent resistance threshold without confirmation

The page's explicit low/high resistance examples name the sensor A code family. It does not separately establish that those exact values apply to every sensor B circuit. Use the actual vehicle's sender scaling and wiring procedure before applying a numerical limit.

Verification should demonstrate a valid B electrical input throughout the relevant monitoring period, then reassess any noise or stuck-reading concerns separately. The source does not determine whether a sender, harness, supply or control input caused the low state and supplies no universal tank-access or replacement instruction. Correct fuel-level interpretation depends on resolving the circuit evidence first.

Source and applicability

This explanation covers the cited Ford monitor variants, not every vehicle displaying this code. Match the engine, sensor architecture and calibration before applying numerical limits.
