i have a 02 super crew with the 5.4 i just put in a k&n cone filter with a maf aapter this filter is very big about 14inch long and 4.5 around and day afer i had it in my ses light came on any way to fix it i take it is from my filter the truck seems to run fine just hate seeing the ses light is thare a way to turn it off easy also i will be selling this filter if i keeps it up so anyone wants it let me no nothing wrong with it in perfect shape

 

Not sure what the MAF adapter is but you need to make sure the MAF has the same orientation as it did stock.Also make sure you have no air leaks.
You can clear the CEL by disconnecting both battery terminals for about 20 minutes.If it does it again i would put the stocker back on!!!

 

Why do you have a adapter on an 02? I've seen them 3 and 4 " adapters but you do'nt need one . I think those are for the 04 plus units - or the lightnings maybe..

 

i have to have adapter because otherwise it wont fit because it is square so if i make sure everything is just nice and tight and goin right derecion it should be fine should jst filter make it set the ses light off

 

start out by telling us the code it is throwing.

 

i couldnt say dont have a code reader and also i mean it went on like 25 min afer filter went on

 

That will happen if the MAF isn't plugged in properly - or it's got something on it - contaminated . Is your IAT plugged in as well?

If all that's fine then head up to auto zone next chance you get and get the code pulled - It's free there..

You want to copy down the number from the reader, that's all you want . Don't go by what they tell you as to the problem - Copy the numbers down on the reader . Have paper and pencil with you..

Then report them back here, we can figure it out from there..

You know , it's possible you just need a reboot. Try unhooking the battery for 15 minutes. While your waiting , make sure everything is plugged in good.

 

ill no tomarow if it is fixed it wasnt pluged in all the way will light go off it self or will i need to do it

 

You'll prolly still have to disconnect the battery to reset. Glad you found it , I've done that many times over the years .

 

ok well light is no more thanks
