What happened when owners saw P0463?
10 of the 24 reports, spread across the models above, as the owners wrote them. NHTSA removes names and VINs; long reports are trimmed. CarHooq has not verified individual claims.
Check Engine light came on with a code P0463. This indicates that the fuel level sensor is bad. This is a VERY common issue on these trucks. It causes the vehicle to no longer go into "ECO" mode which is wasting fuel. This happens every time I fill the gas tank and does not go away until the tank reaches 3/4 tank. The part is garbage and is known to fail.
The fuel gauge in my vehicle is not functioning correctly. It is showing that my fuel level is very low/empty even with a full tank of gas. I took it to the repair shop and the it had the codes P0452 for the fuel tank pressure sensor circuit and P0463 for the fuel level sensor. The repair shop replaced the fuel pump module which did not fix the problem. They suggested it appears to have an ECM issue. This exact problem is a recall on the 2014 Chevy Traverse however my vehicle is not included in this recall.
THE FUEL TRANSFER PUMP, WHICH MOVES FUEL FROM THE REAR TANK TO THE FRONT TANK HAS MALFUNCTIONED. THIS HAS CAUSED THE FUEL GAUGE TO READ INACCURATELY, CAUSING ENGINE TO STOP RUNNING, HAS ILLUMINATED THE SERVICE ENGINE LIGHT MULTIPLE TIMES, DISPLAYING CODE P2068 AND P0463. VEHICLE CAN RUN OUT OF FUEL UNEXPECTEDLY, DUE TO GAUGE SHOWING MORE FUEL THAN IS AVAILABLE. THIS HAS CAUSED THE ENGINE TO STALL UNEXPECTEDLY. THIS PROBLEM IS EXACTLY AS DESCRIBED IN RECALL DOCUMENT 13421 FROM GM, HOWEVER, THE VIN NUMBER OF MY VEHICLE IS NOT INCLUDED IN THE RECALL. I HAD AN INDEPENDENT AUTO REPAIR SHOP VERIFY THE CAUSE OF THE SERVICE ENGINE LIGHT CODES, AND THEIR FINDINGS ARE CONSISTENT WITH MINE. THE VEHICLE…
Fuel sensor issues. 100's of complaints on Fuel Sensors and many reported to NHTSA. The gas gauge will not work and check engine light on, when checking code it is P0463,that is fuel sensor issue. It is dangerous not to know how much fuel is in tank. Again very common issue on Rams with 40K miles and less. Ram know about all these cases. It is a common problem that is ignored by Ram.
THE FUEL GAUGE READS INCORRECTLY AND WHEN THIS HAPPENS THE TRACTION CONTROL LIGHT COMES ON. THERE HAVE 2 2EA FUEL LEVEL SENSORS INSTALLED WITH NO LUCK IN KEEPING THE CHECK WILL RETURN. THE ARE CODES P0463, P069E AND C0045.
Fuel Level Sensor A Circuit - P0463. Yes, available for inspection. The Fuel level sensor cuts out and stops reporting fuel levels. This can lead to running out of gas on the highway or other dangerous situations that put the driver and others at risk. Also, the computer monitors stop reporting, therefore other aspects of the vehicle are compromised when the fuel level sensor stops working. The dealer confirms this is a common problem on this vehicle. Yes the vehicle was inspected by the dealer. The warning lamp check engine light comes on when the system fails. there is no prior warning.
I had about 3/4 of a tank of gas. I noticed my fuel gauge go down to empty, and the low fuel light started blinking. It then when back up to about 3/4. It did this a couple of times until it stayed on empty, and the check engine light came on. The next time I started my truck, I got a "Fuel Sensor Fail" notification. I get that every time I start up. When I filled my tank, the gauge began to work again, but I still had a check engine light. I checked my codes, and had a P0463 code, which indicates a fuel sensor fail. I cleared the code, and the gauge worked for about a day and half. When I got to about 3/4 of a tank of gas again, it all happened again. I have about 78,000 miles.
The fuel sending unit failed on several occasions. The vehicle display would indicate low fuel and the gauge would go to full empty. On the third time it displayed I also got a check ending light. Not knowing if the tank was really empty, I filled and it took 11 gallons for a 26 gallon tank. Dealer indicated code P0463 fuel level sensor failure. Online there are lots of complaints of this happening with less than 50k miles. Why hasn't this become a recall? it is not safe to have sensor fail while driving due to distraction. Not to mention an unnecessary expense for the owner. Ram should have corrected this issue long before the 2017 model year.

MY TRUCKS GAS PUMP ICON STARTED FLASHING AFTER THE WARNING DINGER WENT OFF ON MY 2016 RAM 1500 CREW CAB SPORT. I THEN NOTICED MY GAS GAUGE SHOWED EMPTY. I CHECKED MY TRIP METER AND SAW THAT ONLY 86 MILES HAD BEEN DRIVEN SINCE I LAST FILLED UP. I WAS DRIVING HOME FROM ANCHORAGE AND IN THE MIDDLE OF THE PASS . IT WAS LATE, DARK AND SNOWING WITH NO CELL SERVICE AND NO GAS STATIONS FOR MILES, NEEDLESS TO SAY I WAS STRESSED OUT UNTILL I HAD MY TRUCK SCANNED THE NEXT DAY, AND THE ACTIVE CODE IS P0463, FUEL LEVEL SENSOR. I'VE DONE SOME RESEARCH AND IT SEEMS TO BE AN INHERENT PROBLEM WITH MANY DODGE VEHICLES, NOT JUST TRUCKS. I FEEL THE COMPANY SHOULD RECALL THEIR INFERIOR PARTS AND ADDRESS THIS…
P0463: questions drivers ask
What does code P0463 mean?
P0463 is a generic OBD-II powertrain code. Its standard definition is "Fuel Level Sensor 'A' Circuit High". The code tells you which system set the fault, not which part failed; the owner reports on this page show what it meant in practice for 3 car models.
Which cars get code P0463 most often?
In NHTSA owner complaints, P0463 is mentioned most for the Ram 1500 (21), Chevrolet Traverse (2), Chevrolet Silverado (1), across 3 models and model years 2014 to 2017. Popular models collect more reports because more of them are on the road.
Is there a recall for code P0463?
No NHTSA recall text names P0463 directly. 3 recalls on the cars that report this code concern the same component owners name most (Fuel/Propulsion System); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.
What should I do if my car shows P0463?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
