Overheated now engine light is on?

It had a slow leak of coolant, had it checked out and tightened a few hoses
and the leak was a lot better. I check the water every few weeks and top off. I
have driven it back and forth several times to Los Angeles from 3 1/2 hours
north, no problems, was beautiful! I did this during summer months in the
heat. Ran A/C no problems.
Monday- Oct 12 2020  It over heated after work. The outside temp was
about 95. I hadn't gone far, maybe 7 miles on the highway at about 75 mph.
It had overheated as soon as I arrived to my destination. I was at the car
wash, I pulled in, put it in neutral and turned off the engine.  Went through
the wash, when it ended I started it back up and the temp gauge went back
to normal.
I pulled into a vacuum space to check the water level just in case. I waited
about 5 minutes for the car to cool down and removed the radiator cap, there
was still some pressure built up so it spewed some fluid. I topped off with
water I carry with me at all times. I checked the oil and seen that maybe it
needed a little, so I stopped at Target and bought a quart and put it in,
checked the dip stick again and the level was perfect again. (Oil changed in
August)
Tuesday I drove it about 80 miles through out the day, turn on and off the car
several times throughout various stops, and it ran great, had A/C running,
hot day again about 94. No activity on Wednesday.
This morning, Thursday Oct 15th, I started it and it started funny. engine light
flashed and engine or fan sounded weird so I turned it off for about 1
minute.... the A/C was not on nor the fan or defrost. I started it back up, it
sounded right this time, but the engine light came on and stayed on. I drove
to work, about 35 miles, and it ran fine, stopped at 7-11 and turned off, then
back on and it was fine, other than the engine light being on.
Anyone have any insight, I have a friend that works on Hondas but he hasn't
contacted me back yet.
