Some vehicles have two these days. One is for the ecm and the other is for the gauge. Coolant sensor is for the ecm, I think.

The coolant temperature sensor should be located near the upper coolant hose where it enters the engine block, just a few inches nearer to the windshield. It is usually a gold color.

The coolant sensor is on top of the engine. It is between the ignition coil and the tfi module.
A coolant sensor could be a liquid level sensor and the other is a temp sensor OR The coolant is different temperatures at different places inside the engine and way way cooler when it comes out of the radiator so where the two sensors are mounted can cause difference's. OR they are two different pieces and calibration will not be identical and they will produce slightly different readings.
The coolant temp sensor is located between number 3 & 5 spark plugs on the drivers side cylinder head.
It does not have a coolant sensor, But it does have a temperature gauge sensor and you can find it screewed into the driverside head between the first 2 spark plugs up front,
it is mounted to the strut tower between it and the firewall on the passenger side
