P2067Fuel Level Sensor B Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2067 sets when the input from the second fuel level sender drops below its valid floor, usually a grounded signal wire or a sender resistance near zero. Ford's saddle-tank trucks flag it below 5 ohms (under one A/D count) and allow 30 s for the electrical check. GM's 2020 table, written for dual-tank vehicles, sets it when the secondary sender reads under 10 % of its 5 V range in 100 of 125 samples; Type B, two trips. Mercedes lists it as P206700, the secondary fill level sender grounded. Two bulletins point away from the tank: on 2021 Pacifica and Voyager the code appeared on front-drive vans running all-wheel-drive PCM software, and Genesis issued an ECM logic update for P2067 on the 2018 G80 5.0, where Hyundai calls sensor B the main sender. Driving is unaffected; the gauge is not.
- What you may notice
- MIL on with no change in driving
- Fuel gauge too low, empty or dropping suddenly
- Low fuel warning without reason
- Likely causes
- LikelySender signal wire shorted to ground or chafed on the tank strap
- PossibleSender card shorted internally
- PossiblePCM software for the wrong drivetrain or tank version
- RareDiagnostic logic needing an ECM update (Genesis G80)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €0 – €450
