P2068 on Jeep
Fuel Level Sensor "B" Circuit High Input
P2068 on Jeep vehicles indicates fuel level sensor "b" circuit high input. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. Set when the PCM detects the Fuel Level Sensor 'B' signal voltage is higher than expected, typically indicating an open circuit, short to voltage, or a failed sender. Typical repair costs on Jeep range from $200 to $600, depending on the specific model and root cause.
Common Causes of P2068
- •Open in signal or ground circuit
- •Short to voltage (power) in the signal wire
- •Faulty fuel level sender 'B'
- •Corroded connector / high resistance
- •PCM/ECM fault (rare)

- Fuel Level Sending Unit Failure Causing Inaccurate Gauge and 'Service Fuel Level Sensor' / P2068 (WK2 Saddle Tank)2011-2021
The WK2 uses a saddle-style fuel tank with two fuel-level senders (one per lobe). The sender floats/rheostats stick or wear, and the PCM flags a sender that no longer tracks fuel consumption, setting P2068 (or related P0461/P0463) and a 'Service Fuel Level Sensor' message. Symptoms include a gauge stuck on Full or Empty, wildly bouncing readings, and an inaccurate Distance-to-Empty. It usually doesn't affect running but can strand an owner who trusts a stuck-full gauge, and it commonly requires dropping the tank to access the sender/module.
