P2067 — Fuel Level Sensor B Circuit Low

P2067: Fuel Level Sensor B Circuit Low — what it means, the affected system and what to check before replacing parts.

Meaning, symptoms, causes and checks

Fuel-level sensor B: The electrical input is below its permitted range. This signal-level finding does not by itself establish a mechanical failure. B identifies the second named sensing channel, not a universal side of the tank. An electrical low/high result does not by itself prove the fuel level is physically low/high.

Affected system: Fuel-level measurement

Symptoms

  • Warning light may illuminate
  • Related system function may be impaired
  • Vehicle-specific symptoms vary

Possible causes

  • Fuel supply or pressure issue, restricted injector, actuator fault, connector or wiring damage
  • Related wiring, connector, power or ground fault
  • Vehicle-specific mechanical or control issue

What to check

  • Record stored and pending codes and freeze-frame data
  • Check fuel supply and pressure readings, electrical supply and ground, and the relevant injector or regulator circuit before replacing parts.
  • Confirm measured values against the vehicle service information
  • Retest under the conditions that set the code
  • Check fuel supply and pressure readings, electrical supply and ground, and the relevant injector or regulator circuit before replacing parts.
  • Repair the verified cause and confirm the code does not return

Also written as: P2067-00, P206700 (some scan tools add the fault-type byte, e.g. -00).
