I have recently replaced my coolant sensor because it was litterally broken in half. My vehicle is still not acting right and when I got the code it showed coolant temperature voltage too high. I was thinking it could be the wire leads going into the sensor itself. Any suggestions.

If the wire or connector to the sensor is broken or high resistance, it would show sensor voltage high. Check the connector and wiring back to the controller. Also check that the sensor has some continuity with resistance to be sure that the sensor is OK.

There is a connector replacement for this Coolant Sensor that has yellow and black wires. Did you get a new one, because these connectors and wiring pigtails have a history of problems.
Coolant Sensor Location?
Keep getting P0118 and P0123. Vehicle begins to buck and hesitate when this happens also see the temp guage bottom out. Replaced temp sensor and it shows a little improvement. Thanks!
I would like to know where is my coolant temperature where is located in my truck
1 sensor on top front of engine near thermostat. The other on left lower side of engine near manifold.
i replaced the coolant temperature sensor in an attempt to get my temperature gauge to work but it still doesn't move, what else may be the problem?
