Hi,
I have a 2009 2.4 liter. (Like it a ton!!!)
The problem seems to happen just after I start the car. Then the car abruptly down shifts HARD, the ESC warning appears, followed shortly by the MIL light PO700. I have an OBDII, and here the funny thing, if I connect that to the car and erase the codes, the car will drive just fine again. I believe, what is happening is, after so many instance of what it may think of as improper shifting or possible short/faulty sensor reading , it then goes into this limp mode.
BTW something similar happened to me sometime ago in my 2006 V-6 Sonata GLS, and that problem was the Gas Pedal malfunctioning sensors.
Anyway, I am not sure what it is, and maybe others had success finding out what this is. I am thinking it may not be a really TCS Malfunction, based on other experiences involving traction control etc, but of course, I can't rule it out. I drove the car for about 40 miles, expressway & city and the car shifted fine after the erase of the code.
Possibly, there is a short, or TCS is truly malfunctioning.
I know too, when it does happen, it does when I press down to accelerate quickly, and then the car seems to bog down (only after start up), and then the ECS appears , etc which leads me to think it could be the MAP sensor or CAMshaft position sensor. But now I am just guessing.
Any experience with this occurrence on the 2.4 engine?
Thanks - Jack :smile:
