I changed my ECT sensor on 99 ford taurus now got p0117 code

Question

Changed my ECT sensor got a little coolant on the connector now it's giving me a p0117 code

Answer 1

You could have air in the coolant system or the connector is not making good contact. I suggest starting by inspecting the ECT connector, if the connector is OK you should bleed the coolant system. If the problem persists you could have a faulty sensor.
