My engine light always comes on, and it is always the sensors.
If I replace the sensors it says are the problems will my car ride any better? Is there any use to replace all these sensors other then to make the engine light go away?
I've searched and haven't got any answers. I'll I find is arguements about sensors.

 

The sensors are what the ECU uses to know what is going on in the engine. If they are not functioning properly, then the ECU cannot properly operate all of the engine parameters that it controls.

 

knock sensor makes such a big difference in your high end power.........02 sensors - didnt notice much of a difference when they got fried, but they got that nasty CEL away : )
