Lincoln/Mercury Repair: 1997 Mercury Sable error code 1413, mercury sable, air injection

Question
I have a 1997 Mercury Sable  My engine light is on. I'm getting an 1413 error code. The book tells me it's the secondary air injection system monitor circuit low voltage. If you could please let me know what that is and what could be causing this.  And is it something I could fix. Thank you for any help you can provide.  

Answer
Hi Phil,

This is a sensor on the engine. It is likely something you can repair. I was going to try to get a diagram for you but if you go to the dealer's parts department they will have all this for you. Just give the parts counter person the code info and he'll have it. Easy as that! Hope this helps!
