Default Temperature gauge issues

I have a 98 xlt 4.0.

Truck has been out of service for a while and finally recently got it running again. Been driving around town for a few weeks, with no real issues, but after 1 or 2 days of recent highway driving, the temperature guage jumped up to H and stayed there. Even after truck fully cooled down.

Today I replaced the thermostat and temperature SENDING unit, but not the temperature SENSOR for the PCM.

As soon as I got it back together and started it up, the gauge went straight to C. But as I test drove it, the gauge stayed pegged on C the whole time. Even after going on the interstate for a few minutes.

Should I have replaced the SENSOR also?

Thanks in advance.
