    Hello,

    My Detroit Series 60 dash computer read:

    Alert – Coolant Temp Circ High (then) Fuel Temp Circuit High

    After I shut down it is reading normal again

    Thoughts?

    Could be a bad sensor but 2 at same times doubtful, I would check and clean all connections on ecm for starters. All grounds would be a good second choice.
