2003 Ford Focus Electronic Stability Control Esc Problems

While driving on the interstate, your traction control light flashes along with the electronic throttle control light, followed by the check engine light coming on. Shortly after, your engine loses power completely. This has happened three times despite replacing the battery, air filter, and adding fuel system cleaner. This is especially dangerous at highway speeds on busy roads. The fix will likely require diagnostic scanning to identify the underlying electrical or engine control issue causing these warning lights and power loss.
