2003 TC I get the alert at high speeds 65+ any suggestions as to what causes this?:(

I recently had issues with the engine light coming on after I started it. The problem was low voltage and in my case turned out to be a battery problem.

As Burt said probably your battery. 9 times out of 10 that is the culprit. Also check and be sure all leads are tight to and from the battery.
