P0463 and P2067 Hyundai Santa Fe 2007

Question

I replaced both fuel sensors and it didn't help. May be instrument cluster is bad? Or should i replace ECU?  I don't know what to do

Answer 1

P0463 Fuel level sensor A circuit high input

P2067 Fuel level sensor B circuit low input

Circuit high code occur when there is a disconnection as well as circuit low code, somewhere you have a open in the wire from the fuel level sensor, replacing the ECM will just result in the same condition. Somehow there is a poor connection at the fuel level sensor
