Hello all.
What is it about my 2007 Santa Fe that all sensors seem to start failing on it? Now these are the fuel gauge sensors I guess. Codes that I am coming up with are P0464, P0463, P2068. Can anyone tell me how do I go about it?
Thanks!

 

Age

Yep:

P0463 Hyundai - Fuel Level Sensor 'A' Circuit High Input
P0464 Hyundai - Fuel Level Sensor 'A' Circuit Intermittent
P0463 Hyundai - Fuel Level Sensor 'B' Circuit High Input

Possible causes
- Faulty fuel level sensor
- Fuel level sensor harness is open or shorted
- Fuel level sensor circuit poor electrical connection

The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the Engine Control Module (ECM). The fuel level sensor consists of two parts, one is mechanical float and the other side is variable resistor. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

 

this problem is very common on these cars i have read over 75 complaints for this very problem. dealers not warrentee it dealer repair over 600$ doin it yourself pull back seats fuel pump sensors under there in fuel tank left & right sensors replace both. i have same problem waiting for a recall

 

My wife's Santa Fe had the same issue with erratic gas gauge issues. I pulled both units and bought the parts at the dealer. The circuit board on the sensor goes bad---you can actually see the part that rides on the sensor broken off when you remove the old ones. Parts cost me about $150 and it took 2 to 3 hours to repair.

 

Just quoted $550 on this "repair". (8/2/14) 2 questions...

1. Doesn't this fall under 100k mi. Emissions?
2. How to petition Hyundai or FTC for a recall on this?

 

1. No
2. It's not a recall. It's a failed sensor due to age. Suck it up and pay to have it fixed or fix it yourself.

 

That is quite a high quote. The parts from the dealer cost me $150 and it took me about 2-1/2 hours to replace. A dealership tech should be able to accomplish this repair in 2 hours. I would have it quoted at a Hyundai dealer if your not comfortable changing them yourself.

 

Can anyone who has repaired this themself tell me if there are any special tools needed? I thought I read somewhere that a certain tool was required when pulling the tanks? I probably read it wrong. Thanks

 

They make a tool for the sensor retainer but you can just use a brass drift and tap the ring counter clockwise to remove it. You can also use a wide blade screwdriver but be careful not to damage the retaining ring.

Regular sockets with a long extension will allow you to pull the backseat. Change both sensors while you are there---about $150 from the dealer and less than (2) hours work.

 

Never meet a more helpful Wolff! Thank you very, very much.
