Problems with indicator lights and electronics on a Ford Focus

Good day, I own a 2010 Ford Focus with a gasoline engine and 284,000 km on the odometer. I have a problem with warning lights - suddenly three warning lights start flashing at once: parking brake, ESP, and a third one that I can't identify exactly. These lights flash or stay lit for a few seconds, during which the speedometer needle drops to zero. After the lights go out, the needle returns to the current speed. This cycle repeats, and after a few kilometers, the situation calms down for a while. In addition, my left low beam headlight starts flashing and the radio occasionally turns off and on. I found on the internet that such symptoms can be caused by a faulty MAF sensor, but my Duratec engine only has a MAP sensor. Is it the same thing? Would replacement or cleaning help? Or what could be the cause of these problems? Thank you, Tomáš.

A 2010 Ford Focus owner is experiencing issues with multiple warning lights flashing, the speedometer needle dropping to zero, and intermittent problems with the headlight and radio. These symptoms suggest an electrical issue rather than a sensor problem. It is recommended to check the battery connections for cleanliness and tightness and to inspect the alternator to ensure it is charging the battery properly, as a failing alternator or poor battery connection could cause these issues.

It sounds like you might be dealing with an electrical issue rather than a sensor problem. Start by checking the battery connections and ensure they are clean and tight. Also, inspect the alternator to ensure it's charging the battery properly. A failing alternator or poor battery connection can cause multiple electrical issues, including the ones you're experiencing. Please check these and let me know how it goes or if you have further questions.
