P0463 on Renault: causes and affected models

P0463 means: fuel level sensor "A" circuit: high input.^[1][2] Renault has 4 documented faults that can trigger it, across 2 engines and 2 models: 1.3 TCe, 1.5 dCi, Renault Scénic II and Renault Laguna III. Only a diagnosis can confirm the cause on your car.

Documented Renault faults that can trigger P0463

Grouped by engine or model, from most to least important. These are faults with the fuel pump and with the instrument cluster: not all of them will necessarily set the code, and only a diagnosis confirms the cause on your car.

1.3 TCe

In Arkana, Austral, Captur II, Clio V, Kadjar, Kangoo III and 2 more models

- High severityFrequency: OccasionalFuelBlown fuel pump fuseOn the Renault Captur II and Clio V with the 1.3 TCe engine, a 20-amp fuse can blow and leave the car without an engine. According to L'argus, in April 2021 this fault still had no factory fix; the official service centre's diagnosis includes checking, and sometimes replacing, the catalytic converter.

1.5 dCi

In Clio II, Clio III, Kangoo I, Kangoo II, Mégane II, Mégane III and 4 more models

- High severityFrequency: OccasionalInjectionDelphi high-pressure pump that sheds filings and damages the injectionOn the first 1.5 dCi engines (up to approx. 2010), especially the versions with Delphi injection of 65, 70 and 85 hp, the high-pressure pump can shed iron filings that contaminate the whole circuit and destroy the injectors. The pump, injectors and rail all have to be replaced.Appears at around 60,000 km

Renault Scénic II

- Medium severityFrequency: OccasionalElectronics and infotainmentCentral instrument cluster failure (switches off or resets the mileage)The Scénic II's central digital instrument cluster can switch off completely or stop displaying the mileage properly, a fault documented mainly between 80,000 and 170,000 km.Repair: €900–€1,200Appears at around 80,000 km

Renault Laguna III

- Low severityFrequency: CommonElectronics and infotainmentInstrument cluster and Carminat TomTom sat nav faultsThe Laguna III has fairly frequent electronic problems in the instrument cluster and freezes or position errors in the Carminat TomTom sat nav, as well as a car radio that stops ejecting CDs in extreme temperatures.

Common causes of P0463 on any make

From most to least likely, according to the sources.

1Level sensor (float resistor) open or corroded inside the pump module, the most common cause according to AutoDTCs.^[1][2]
2Float arm bent, broken or stuck, so that the wiper loses contact.^[1]
3Signal wire open or chafed between the sensor and the ECU or cluster.^[1][2]
4Loose or corroded connector at the pump module or at a splice.^[1][2]

What to check first

The first diagnostic steps, from the most likely and cheapest to check to the most expensive.

1With a diagnostic tool, read the fuel level value and compare it with the fuel actually in the tank.^[1]
2Inspect the pump module connector (usually under the rear seat) for corrosion or pushed-in pins and wiggle the wiring while watching the live value.^[1]
3Check the continuity of the signal wire to the ECU or cluster.^[1]

Frequently asked questions

Which Renault models have faults that can trigger P0463?

1.3 TCe (1 fault), 1.5 dCi (1 fault), Renault Scénic II (1 fault) and Renault Laguna III (1 fault). Each fault has its own page with the affected years and versions, the symptoms and the repair cost.

What does code P0463 mean on a Renault?

Fuel level sensor "A" circuit: high input. The ECU has read a voltage above its normal range from fuel level sensor "A" for a period of time. It is a generic OBD-II code: it means the same on a Renault as on any other make.^[1][2]

Can I keep driving with P0463?

Monitor. It does not damage the engine, but an unreliable gauge can leave you without fuel: refuel soon and keep track of the kilometres. It keeps the warning light on and may fail the emissions test.^[1]
