down to one code p1118 no other codes


Asked by Sep 11, 2015 at 07:47 PM about the 2004 Hyundai XG350 4 Dr STD Sedan

Question type: Maintenance & Repair

replaced TB, TBS, TB Motor, APS  now what?  Checked fuses.  Scanner
shows all O2's are working.  Cleaned TB.  Cleaned all connectors at TB.
Car is stuck in limp mode.  Pulled the ECU and sent it to be tested and all
pins are good.
TSB show open circuit or bad wiring???  Don't know how to do this.
I have another 2002 xg350L which is running fine and I switch the parts
between them to test.  So far parts from the 2002 put on the 2004 have not
corrected the issue and the parts put on the 2002 from the 2004 have
worked fine.
Any other suggestions?

I think you need to get the car flashed or the ecm reprogrammed to remove the codes...


when I had the ecu box in center dash tested they also flashed it but no change.
