This is a fantastic overview of the basic sensors in an internal combustion engine. As someone who is interested in cars, I found it very informative and easy to understand. Thank you for sharing!

Hey Bro, I like your videos are very helpful. Btw i got a question, which sensor controls the electronic EGR valve because my hyundai accent egr valve is opening/closing at a wrong time thats why my car jerks sometimes.

[@brightsource206]

Hi there, EGR valve is completely depended on MAP and MAF sensors. It also uses pedal position sensors readings too. So the ECM uses data from these 3 components and control EGR accordingly.

@@brightsource206 ok thank you, big help. I remember my car hesitates almost every morning when i use it but doesnt happen at idle. After driving for about 5 to 10 km i park it, and drive again and the jerking go away sometimes. Even when ive driving the for hours sometimes it hesitates. Thats i need to park for awhile and drive again and It goes away sometimes. U might have an idea with this. Your thoughts will be much appreciated bro. I have this prob for 3 yrs now.

This might be a problem with EGR or Throttle Body.

@@brightsource206 i already replaced the whole egr but not OEM. probably you're right coz i noticed my Throttle body is always open and does not respond to my pedal but sometimes it reacts when i pressed the pedal and the jerking goes away. But i dont have any error code for throttle body on my scanner. But the throttle body will close and open for few seconds when i first start the engine, it also moves when i stop the engine.

Is that a diesel or petrol head?
