1997 Cherokee Sport 4Door, 4WD
4.0
Check engine light came on and from turning the key on and off a few
times and leaving it in the 'on' position, the codes came up with a 12
and a 45.
From what I google, a 12 just means that I had unhooked the battery
to try and clear the codes, which I had done.
But what is a code 45?
If it might help, I was running hard pulling a loaded 5' X 10' U-Haul
trailer 130 miles into a head wind at about 60-65mph yesterday. Unhooked
and headed out to WalMart to get groceries and noticed 'check engine'
light on. At WalMart unhooked the battery to clear the code while we
shopped. Came back out, hooked battery back up and check engine light
came on about 30 seconds later.
TIA
