My check engine light came on - took it to a garage and they came up with there was a problem w/the fuel pump but took it for a ride and could find nothing out of the ordinary happening. The reset it, but a few days later it came back on. I bought a pocket scan and the error code was P0183 - I reset it but it came back on within a day. The car drives fine - should I be concerned - do I replace the fuel pump?

 

Did you ever get a resolution? I am having the same issue with a 2004 Hyundai Santa Fe. The engine runs fine, but the check engine light comes on every few days with the same P0183 code. It shows as a serious engine code, but don't want to spend unnecessary money on an older vehicle.

Thanks

 

P0183 = Fuel Temperature Sensor A high input

Most likely bad fuel temp sensor. Check and replace if needed.

DTC P0183 - FUEL TEMPERATURE SENSOR, TERMINAL "A" IS INTERMITTANT

DESCRIPTION:
A new Fuel Temperature Sensor (FTS) has been introduced in the 2003 model year 2.4L and 3.5L Santa Fe, 2.4L Sonata and XG350. The new sensor measures fuel temperature in the fuel tank. The ECM uses this information for the Evaporative Emissions Self Check.

Fuel vapor pressure increases when fuel temperature increases. The ECM references the fuel temperature and indirectly compensates for the fuel vapor pressure during the evaporative emissions leak check. The FTS is located inside the fuel tank and is mounted to the fuel pump assembly.

The ECM can set Diagnostic Trouble Codes (DTC) relating to the FTS: - P0183 = Open Circuit, Signal voltage is greater than 4.6V

PART NUMBER INFORMATION:

- 31435-38300 (Production Date 10/19/02 to current)



I don't think you would need to replace the whole fuel pump assembly. Tell your dealer to look up TSB # 03-36-015

 

Yes I did resolve it - ordered the fuel temp. sensor which is located in the gas tank under the passenger seat behind the drivers seat. Relatively easy once you get the new part and know what you are looking for in the gas tank. Its been a while but I believe the part was about 34.00 - My only mistake was I first attempted to locate fuel pump behind passenger seat. I am a 64 year old woman who likes doing my own repairs, if possible, so I am quite sure you can handle the task easily. I have a 2004 Hyundai 6 cyl GLS and the part I ordered 3143538300 from www.hyundaipartswholesale.com 866-505-3639 that was in june of 2011.
Just lookd it up part was 34.00 shipping was 9.99
Good luck

 

I have a 2005 Santa fe with a p0183 code .
I changed the fuel temp sensor and cleared the code ,and after driving about 20 miles it came back on. Any suggestions?
