Check engine light is on and after getting tested it came up that the coolant sensor was bad. Replaced that and light remained on. Disconnected negative terminal and still nothing. Got tested again at AZ and it still shows the same issue. Is there something I am missing on this?

There are two sensors for coolant. Did they replace the right one? the single wire sensor is for the cluster, the other is the PCM. They're right next to eachother.
