My car was parked outside for a day and a half. It had been raining very heavy. I drove about 4 miles, parked and returned to the car about an hour later. I drove out of the parking lot on to the street and the check engine light came on. The car then bogged as I accelerated until I got past 30 mph. I drove home and had a mechanic scan for the trouble code which was P2125 throttle/pedal position sensor/switch E Circuit. He does not repair those issues. I drove the car today, light still on but no bogging what so ever. Drove on a road with a very long incline and it was fine. Is this the beginning of a major issue or is this a minor issue that if corrected will prevent a major issue like needing to replace the entire throttle. I did drop the car off at repair shop near by that works on that issue on the Hyndai XG. They do a 12 point inspection, try to reduplicate the issue (which it is no longer there), and analyze the code. I am trying to stay a step ahead as I have read experiences of others paying for repairs that did not solve the problem. Is it possible for this code to be caused by transmission or other engine issues?
Thank you in advance, all advise and info is welcome
