Code 1155 on a 2004 Hyundai XG350L typically indicates a problem with the throttle position sensor (TPS) or its circuit. To fix it, first check the TPS connector for any loose or damaged wiring, and ensure it's securely connected. If the wiring is intact, test the TPS itself with a multimeter to see if it’s functioning within the specified parameters; replace it if necessary. Finally, clear the code and perform a test drive to see if it returns.
I had the same problem...the alternator went bad. Both the alternator and battery had to be replaced.
To fix the limp home valve on a 2004 Hyundai XG350L, first, diagnose the issue by checking for any diagnostic trouble codes (DTCs) using an OBD-II scanner. If the valve is faulty, you may need to replace it; this typically involves removing the intake manifold for access. Ensure all electrical connections are secure and inspect vacuum lines for leaks, as these can also cause limp home mode. After repairs, clear any codes and test drive the vehicle to confirm proper operation.
I found an Internet site which says how to program the keyless entry remote. But there is an error: this procedure is good for Elantra 2001 to 2003. Elantra 2004 must be programmed by the dealer. http://car.justanswer.com/hyundai/n1kw-program-remote-entry-hyundai-2004
