Question about 2003 Hyundai Santa Fe

1 Answer

Hi, I have a Hyundai Santa Fe 2003 SUV. It has about 110000 Km on its odometer. Recently, I have noticed that sometimes when I drive faster than 100 Km/h (60 Miles/h) on the HW its speed drops drastically for a second and if goes back up again. It feels like a very sudden and sever engine hiccup. Have you heard about this problem with Santa Fe 2003? What could be wrong? I appreciate any hints or feedbacks Thanks

First things first. My experience tells me you need to test a few things first before you spend a lot of money. Find an OBDII scanner & check for any powertrain trouble codes (DTC's). If any, investigate & repair as needed.
1. Check fluid level & condition of trans - should be at the 'full' mark and relatively clean. If low or dirty, replace & adjust level. Use ONLY Hyundai SPIII fluid.
2. Check/test the throttle position sensor (potentiometer) for any bad spots (use an analog ohm meter).. if you don't know how to do it, find someone who does. Replace as needed.
3. ZERO out the TCM (PCM). This clears all adaptive values in the computer (this computer is a learning computer and accumulates driver's driving habits). This can be done by disconnectiong both battery cables and touching them together for 30 seconds. Then reconnect them to the battery.
4. Now, if your Santa Fe has the 3.5 lit V6, then your engine is equipped with the ETS (Electronic Throttle System) which incorporates another sensor called the APS - Accelerator Position Sensor - check this one as well (also a potentiometer). replace as needed.

I have a 2003 Hyundai Santa Fe and suddenly the speedometer, odometer and trip setting have stopped working.


I would check all of your fuses to make sure none of them have blown. Also your odometer and trip settings are based off of you speedometer is if it breaks it will take keep other things from working until it is repaired. also if you feel any difference in your shifting it can be due to the fact the your speedometer is not working I would take it to a certified auto shop as soon as possible if a blown fuse is not the cause of your problem.

I hope this helped.

Thank you,
Norse
