Question about 2004 Hyundai Santa Fe
Had the same problem. Was told there are 2 sensors, one on the throttle body the other one was at the pedal. Check the one at the pedal. Was having the same problems as the original poster had, for 4 years, before they finally figured it out.
If this is what I think it is, on the 3.5 Lit V6, you have an APS (Accelerator Position Sensor) and a TPS (Throttle Position Sensor). The accelerator pedal cable is NOT directly connected to the throttle body plate, it's connected to the APS. The APS sends its signal to the ETSCM (Electronic Throttle System Control Module) which in turn activates the ETS Motor located on the throttle body which opens/closes the throttle plate/butterfly. It's a very sofisticated electronic system. Both the APS and the TPS are known to go bad and simply replacing them is no guarantee of fixing problems in this system (often times it does, and frequently it doesn't). You should first verify there is a problem with these sensors (APS and or TPS). They are basic potentiometers (two circuits in each) which provide data to the computer regarding throttle opening for LOAD calculations (ignition timing, fuel injector pulse width, cruise control operation, etc). Best you have this system diagnosed by a professional technician who knows the system.
