Question about 2001 Hyundai Sonata
Yesterday, I was driving at about 40-45 mph, and all of a sudden the engine revs up to 3000-4000 rpms. I come to a stop light the engine is still at that same high level of rpms with my foot on the brake. I found that when I was going up a steep hill, I didn't need to put my foot on the accelerator because I was coasting just fine up a hill at 45 mph. We parked the car and it wouldn't turn back on. After not touching it for 30 minutes, we came back to the car and the check engine light was on and the problem was gone. I have a 2001 Hyundai Sonata Automatic V6.
THERE IS A TEMPERATURE SENSOR ON MOTOR WHICH CAUSES THIS PROBLEM... USUALLY IT SHOWS A NEGATIVE TEMP READING WHICH CONFUSES THE COMPUTER CAUSING IT TO REV UP....HAVE THE ENGINE DIAGNOSED ON A SCANNER....GOOD LUCK...
