Thank you for this concise information. I'm getting the EPC light more frequently now (Aug 2024) In fact today, just now, my EPC came on and then I got new messages like "Max RPM 4000!", mean while I'm in Southern California driving at 35 mph. I also got only moments later the temperature gauge on my car went up to almost 280 degrees I knew there was nothing wrong, but needless to say, as a precautionary move, I shut it off before it redlined. Then simply waiting 30-45 seconds and starting the car and all the problems go away... temperature is back to normal readings, the EPC light is off etc.
I'm getting tired of it so I'm going to hopefully get a mechanic to look at this because I'm tired of it. I'm tired of all the false flags. Thank you for this video.
