OBD-II code family
Fuel Level Sensor A Faults (5 codes)
5 related fault descriptions. Use each full code and the exact vehicle service information to identify its circuit, monitored condition, and required tests.
Codes in this family
This is the complete published member list for this guide. Each code retains its own page; shared diagnostic context does not mean that every member has the same test or repair.
What these codes mean
P0460 describes fuel-level input A circuit context. P0461 names range/performance, P0462 low, P0463 high and P0464 an intermittent condition. These monitor results do not directly measure the remaining fuel quantity or identify a complete pump assembly as the repair.
Identify the reporting module, full code and installed sender arrangement. A does not universally mean a primary pump, a particular tank lobe or a fixed location. The display, raw input and receiving controller can use different update or filtering rules. A steady gauge alone does not certify the monitored circuit.
The full subtype determines which check applies. Ford’s covered 2024–2025 summary identifies P0461/P0460_1C as noisy, separate from the stuck-input check. Low/high does not establish one gauge direction or a universal open/short diagnosis. Do not substitute another model’s sender curve or a jumper response for the required test.
Manufacturer cases also distinguish the job. Nissan NTB22-026 allows separately diagnosed sensor replacement within its 2016–2022 scope. Mazda SA-013/25 concerns a sub-sender on specified CX-90/CX-70 H3T vehicles and can include no-start despite displayed fuel. GM 18-NA-365 considers transfer-system behavior and both inputs on listed AWD/F48 applications. None authorizes that repair on every vehicle.
Save the scan and event history, inspect accessible cooled connections and have the prescribed input, circuit, mechanism or transfer checks performed. Fuel-system access needs the actual isolation and handling procedure. Do not drive deliberately to empty a tank, reproduce a fault on rough roads or bridge unknown sender pins. Price the confirmed job and verify the relevant input and monitors; a diagnostic-service example is not a tank-access or repair package.
Identify the circuit on your vehicle
Match the full DTC, reporting module, and any failure-type suffix to the service information for your exact year, make, model, engine, and equipment. An identifier alone does not establish installed hardware count, location, connector pinout, or a universal measurement.
Where the manufacturer publishes its own meaning for this code, that is the one to work from — it describes the actual component on your vehicle, which the generic definition cannot. Keep the generic description for what it is good for: it tells you which subject area the standard assigned the code to, which is useful context when the two appear to disagree. If they do disagree, follow the manufacturer.
