My civic when I put on my high beam lights my temperature gauge goes full and so does my gas hand go full, I have two sensors gone the one that turns on my coolent engine fan and a speed sensor , what's wrong with my gauges ?

You are completing a ground to your instrument cluster when you turn on your high beams and your high beam indicator comes on. The ground is taking the wrong path of least resistance. The proper ground has been disconnected somewhere.
Maybe behind the cluster. You'll have to think back to what wiring has been disturbed since this has happened.
New gauges? Sound system? Looks like some serious electrical troubleshooting is in order. Are you up to it?
What is the meaning of 2 sensors gone? Confused.
And the speed sensor raises some red flags in my book because that would tie in with the cluster.
