the check engine light on my 2002 dodge ram van 1500 will not go off for emissions test

 

First thing you'll need to do is get a scanner to see what code(s) you have.

 

Exactly. Get the code read. It is telling you what’s wrong.

 

If you don't have your own scanner , you can get it done at a parts store like autozone for free or whatever parts house in you area , post the code would be helpful as it could be many things , common thing is usually an 02 sensor code but not every time ,, they can clear it with a good scanner or you can unhook your battery terminals for 20 minutes or so to clear , it may come right back or may stay off depending on issue , but you need to know the code first to see what caused it in the first place ,, even an loose fuel cap can set a code off , as well as many sensors or failed component
