Hi everyone, I need to see if I can get some help sorting out an engine code issue. We recently got the wife a 96 Cherokee Laredo and it's now indicating check engine all the time...nice...
When I broke down the codes it shows 12, 72, 55
From what I am reading here and other places....the 55 is the end of codes and 72 is an issue with the ambient air temp sensor but the code 12 is throwing me fits...I have read it means nothing and also that it indicates a retarded timing issue on bank1. Next I read that anytime there is a code set that the timing is retarded 10 degrees automatically....yikes.
SOooooo Do I care about the code 12? Is it nothing or is it showing because the ambient air sensor is malf and caused a retarded timing condition?
Yeah, I read too much..LOL Sorry, just don't want to pay someone to fix something I can do myself. If the 12 is valid, what is the fix for it?
Thanks everyone! Todd
