I Was Driving Home Yesterday, And My Service Engine Soon Light Came On. Just Wondering What Is The Different Between The Check Engine Light And The Service Engine Soon Light? And What Should I Do? Can I Get A Code From Autozone? Any Informaton Will Be Helpful.

 

1. They are the same
2. Yes, go to Autozone
3. Fix the problem

 

Service Engine Soon = Preventative Maintenance so something doesnt break prematurely

Check Engine Light = Something is wrong most likely

 

thanks i will get the code from autozone today.

 

They are both the same as far as the evo is concerned. The evo has no maintenance lights that I am aware of like a Honda does. Different manufacturers have different ways of letting you know the ECU threw a code and the evo has "Service Engine Soon".

 

you should start panicking! please, dont drive your car anymore until you find out what the problem is!

 

Not on a EVO

 

I hope you're joking.

post what the error code is once you go there

 

The question was answered in general as to what the difference is since he asked the question in general instead of being "Evo Specific" I answered it in general.

I own an EVO and I know that there is no "Maintenance" Light. Only a Check Engine...

 

yessir

 

i went to autozone today, and i got the code for P0300.
while i was driving home, the light went off, any idea what to do next.
i will changed the spark plug next week. i hope this is the problem.

 

P0300 Code - Cylinder Misfire

So just change your plugs and see if it comes back again if it does then you might want to check your coils or plug wires. If you got good scanner you could actually detect which CYL misfire occurred and go from there. Snap-On scanner could do that.

 

Or buy an Accessport........................................ ..

Just Joking....don't ream my life!!!

 

good investment was buying that handheld code reader from autozone. cant remember what its called but i have used it alot.

 

I bought mine on sale for about $50- it wil read and clear codes but it doesn't tell me what the code is. I have that same code pop up every now and again, but after taking it to the dealer several times and having the thing pop codes once then not do it again for a couple of months,it was $50 well spent. Previous owner changed plugs then dealer put new plugs then coils then injectors then injector cleaner. After all was said and done, there's nothing wrong.

PS if you get the one that doesn't give you the code here's the link to the thread with codes
