What does the code po463 mean - Cars & Trucks

Those are zeros, not Os - P0128, etc. Put your car year and model with the code into Google. You'll get all the information you need.

take it to the nearest advance auto they plug in a small computer and it will tell you exactly what those code mean for free or you can buy your own diagnostic computer for about $80

Code 463 is for a problem with the fuel sending unit circuit. The most common cause is a faulty sending unit or a problem with the wiring harness to the tank.

The P0463 code (Fuel Level Sensor Circuit High Voltage) means that your fuel guage circuit is open. To fix the fuel guage, the tank must come out to replace the sending unit. Personally I wouldn't worry about it too much. Use your trip guage and fill up after 200/250 miles. You'll never run out.

PO442 indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.A code P0442 most likely means one or more of the following has happened:

• A loose or improperly affixed gas cap
• A non-conforming gas cap (i.e. not factory/original brand)
• A small leak/hole in a fuel vapor hose/tube
• Other small leak in EVAP system
• Faulty vent o-ring seal

With a P0442, the most common repair is to:

• Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
• Otherwise, replace the gas cap, or
• Inspect the EVAP system for cuts/holes in tubes/hoses

P0463 Fuel Level Sensor Circuit High Voltage

CODE PO463 IS FUEL LEVEL SENSOR FAULTY OR SENSOR WIRE HAS A SHORT.

It means there is a problem in the fuel sending unit circuit. The PCM uses a 5v reference on this system to calculate fuel level. There is either a problem in the sending unit or related wires.

fuel level sending unit voltage high. How is your fuel gage working? Only repair I know is to replace the sensor in the tank.

Trouble code P0463 means:Fuel level sensor circuit,high input

po463 is the fuel level sensor. the oxygen sensors are the ones that send a signal to the computor to adjust the rich/lean fuel mixture. Have them checked.
