I ve nissan pathfinder 2005 model, service engine soon light on. we used a consul and got fault code PO463 fuel level sensor high input. right now car will not start. advice

code p 0183 refers to fuel temperature sensor A --high input===causes --wiring short to positive ---fuel temp sensor--ECM
code p 0463 refers to fuel tank level sensor --high input===causes --wiring short to positive fuel tan level sensor ---ECM
if the temp sender and the fuel level sensor ( both located in the same fitting in the tank)are in the same wiring harness then there may be a connection as the wiring short to positive is common
check for the harness rubbed through somewhere causing the problem or an after market screw screwed into the harness some where

code p 0463 refers to fuel tank level sensor --high input ===causes --wiring short to positive --fuel tank level sensor ---ECM
remove a wire from each at a time to isolate the sensor in question
check the wires for a short to the sensor or in a connection ( water etc)

Hello, Here is website explaining the code you are getting.
P0463 Fuel Level Sensor Circuit High Input

Google bod code P0183 and this will tell you the answer

They are the same. The level switch in the sending unit has shorted out. This will not affect the performance of the car. Like you said it only affects the gauge. The switch can't be purchased seperate from the sending unit. Just guessing yours is $400.00 to $500.00. I would live with out it untill the fuel pump went out. Just estimate the mileage with the amount (gallons) you put in.

Hello the sensor is in your gas tank you will need to replace it not cheap the sensor is about $150.00 labour is what ever you can get the job completed for usually a 3 hour job.it is a big job a hoist is ideal!allot of gas can get spilled so my vice is take it in and have .it done your not alone these are famous for this problem.

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

The fuel level sensor is at fault and is setting the service engine soon light on. Your local Nissan dealer can repair this under warranty depending on your mileage. The fuel tank will need to be removed to access the sending unit.

2006?? if it is then nothing can be done because its encrypted software ,dealer only .The code reader will read the wrong code because of the encryption

yup, nissan has problem with those and yes, there is a service bulletin for the replacement of the fuel level sensor. common problem on your year pathfinder and frontier.
