It’s definitely drilled thru, looks like teeth were drilled thru on the corners and the edges were chipped off. Gonna have to look into swapping the tone ring.

yeah... damage to the tone ring causes false/unstable signals.

Whatever complete idiot, that drilled it out, without dropping the pan and protecting the tone ring should be contributing towards the tone rings replacement.... which is NOT going to be easy to do by any means.

And that’s exactly why I’m still getting erratic rpm readings and bad crankshaft code. I’m going to go to their shop today and figure this out. I hope I can be back up and running soon. Thank you all for the clarification. Will driving it like this effect my ecm? Gotta get the truck to their shop
