P2065 — Fuel Level Sensor B Circuit
A general electrical fault is reported on the secondary fuel-level sensor (B) — vehicles with saddle tanks or auxiliary tanks use a second sender to cover the full tank volume.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.

Check each reference's vehicle and model-year scope. General background links do not establish which fault is most likely on your vehicle.
Diagnostic information is provided for reference only. Confirm the code with a compatible scan tool and follow the vehicle manufacturer's service procedures before replacing components.
