Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Have you tried to clear out the code and see if it starts then at all?

Let me know so we can continue,thanks Pete.

Customer: replied 6 months ago.
No we have not tried to clear codes but wanted to know is there a sensor that puts car in safe mode to prevent it from over heating and shuts off car if so what is it called
Expert:  peterpete190 replied 6 months ago.

There isnt a sensor unless the engine coolant temp sensor fails and sends a false signal of over temp this could cause it but it is the engine computer itself that puts the engine into a fail safe mode with an over heat and can shut down the engine until the code is either cleared out or the over heat condition has been resolved.If your code does not clear out and allow starting or does clear out but it doesnt start it would be the engine coolant temp sensor that can cause this issue needing replaced.
