Jimmy I can't help I never had any codes show up. My car is working good now and haven't had a problem since. worrying about the tranny now.
I have a few good impacts and they didn't move the crank bolt any at all, I was leer about using starter also. After trying it, just a bump, only once and check to see if it is loose mine was a second bump may just run it all the way out and that could send bars and sockets flying so just one quick bump is all you want to do, mine was finger tight after the bump. I will never use a impact to take one off again. I set my 1/2 breaker bar 1" from the frame in front of car bumped it once. So fast an easy.
I forget so much anymore, I won't know nothing before long.
Only works for removing the bolt, it will not work to tighten the bolt. In case anyone is wondering. work safely, it don't pay to get hurt.
