P2068Fuel Level Sensor B Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2068 is the upper limit fault of the second fuel level sender: its signal sits above anything a working sender can produce, which normally means an open circuit, a lost sender ground or a short to a supply voltage. Ford reports it above 200 ohms, more than 253 A/D counts, using the same 30 s electrical check as for sender A. GM's 2020 dual-tank table needs 100 out of 125 samples with the secondary sender above 60 % of the 5 V span, Type B. Mercedes lists it as P206800, the secondary fill level sender shorted to plus. Ford SSM 52771 covers 2024 Bronco Sport, Escape and Corsair that displayed Fuel Level Low with the MIL and P2068 although the tank was not low; its pinpoint test was rewritten. Because the gauge combines both senders, one bad reading skews the whole display.

- MIL on
- Range estimate jumps or is implausible
- Likely causes
- LikelyOpen signal or ground wire, unplugged sender connector
- PossibleSender card worn through or wiper lifted off the track
- RareSignal wire shorted to a supply voltage
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
