Hello everyone.
I had the check light problem twice. Hyundai changed the sensor attached near the throttle body sensor.
The problem was solved. I think it was better that first the car should be checked by the Hyundai people and problem detected. Then it remains to decide whether to repair or replace the sensor / ecu / mother box.
By the way, my throttle body sensor was also replaced because it developed a hairline crack in it.
better to buy an old car without all those sensors. Because if a sensor develops fault while you are travelling with your family, then its a very very big problem.
I bought a 2008 model corolla gli because i thought it didn't have sensors. I later found out that it had 7-8 sensors too.
but new corolla has electronic accelerator and electronic clutch. These in itself are dangerous because dirt will enter their housing and they will develop fault eventually
