I just bought this car yesterday. I drove it home from Lexington, Ky to Indiana (180 miles) and it ran beautifully. It has 133,000 miles.

This morning I go out to start the car (it's cold today 23 degrees) and the car started but the check engine light came on and I tried to press the accelerator during warmup and the engine just idles. I turned off the car and tried it again with the same result. I turned it off and took my wife to work in her minivan.

I'm freaking out now because I've been out of work for 16 months and bought this so I could have a reliable car for when I get another job and now am out a bunch of money.

I would appreciate any insight you could shed on the matter. My understanding was these Hyundai's were goos reliable cars although I know any car will have problems.

Thanks in advance for any insight given.

Need codes to know what is going on... but common part is seen in the pics.

Verify codes, and read the code(s) slowly and carefully... come up with "APS"... this part will solve most of the woes..

* UPDATE*
I went out and started it up a little bit ago after letting it sit for a few hours and it started normally and drove normally. According to Autozone the codes are as follows: P1110, P1175, P1196 and P2127.

Any clue how difficult this is to fix and the approximate cost?

Thanks,
perry

Can anyone tell me if the codes I supplied above match the accelerator position sensor suggested as the culprit? Also, how easy is it to replace for a beginning DIYer?

Thank you for your time and input.

P1110-P1175 Throttle Actuator Control System - Stuck Closed

P1196 ETS LimpHome - Closed Throttle Stuck

P2127 Acceleration Position Sensor 2 Circuit Low Input


Start with the part seen above in previous posts.. before you remove the pull cable from the bracket and arm, note the amount of slop in the cable.. set it similar,, not pulled tight that it hold arm off it rest point..

If you can change a light bulb in the house, you should have no problem changing the APS ... You will need a pair of 12mm wrench I think for the locknuts on the cable, and a 12mm socket for the sensor bod to the bracket..

For the 1196, at worst, clean the throttle body and plate with some carb spray and old tooth brush and rags,,, use long stick to hold throttle pedal down to floor, this will hold plate open so you can clean (key on - engine off)..

1110 - 1175, I would not worry currently, get the APS taken care of and clean the throttle plate, then proceed from there..

BTW - I don't know what a throttle body is or looks like so anymore explanation would be helpful.

Thanks,

Hmmm, are you sure you should be under the hood ?


Picture is of a throttle body, though it belongs to the Hyundai 3.3/3.8 family...

Good question about whether I should be under the hood. My skills around a computer are more honed than my automotive skills, so I probably should not be under the hood but I'm gonna try it anyway.

Thanks again for your expertise and all your visuals.

Somebody claimed it is not fair that I have inventory to take pics of and post pretty quickly.
