I’ve been working on my daughters 13 dart limited with the 2.0. Had a couple coolant leaks. Fixed those, replaced thermostat and temp sensor and now after driving for a few minutes the car tells me the coolant temp is -40, tells me the car is overheating and goes into limp mode. Any ideas? I’m thinking ECU?

Wiring or aftermarket coolant sensor.

What about the wiring?

You possibly pulled too hard on the connector trying to get it off. -40 means no signal.
