what is code p0183 on a 05 hyundai sonata 2.4l ?

Question

I have a check engine light on and code p0183

Answer 1

GENERAL DESCRIPTION 
The fuel temperature sensor is located in the fuel tank for detecting the fuel tank temperature.
The fuel temperature sensor uses a thermistor whose resistance changes with the temperature.
The electrical resistance of the fuel temperature sensor decreases as the temperature increases, and increases as the temperature decreases.
The reference 5 V in the PCM is supplied to the fuel temperature sensor via a resistor in the PCM. The resistor in the PCM and the thermistor in the fuel temperature sensor are connected in series. When the resistance value of the thermistor in fuel temperature sensor changes with variations in fuel tank temperature, the output voltage also changes.

Basically you will likely need to replace the fuel temp sensor to resolve this code.
