I was driving my car 2011 Prius on the freeway suddenly I saw on my dashboard says check the hybrid system. and a yellow triangle on the left and check engine light on the right and a small red circle under it after half a mile driving the car stopped, I garbed my scanner and read the code it showed the code P03190 I checked the possibilities on https://www.autocodes.com one of them was "vehicle is out of fuel" in the end I found out my car was out of fuel but I did not think it was out of fuel for two reasons 1-Faulty gas Gauge: my gas Gauge was showing 3 bars which normally means three gallons of gas remaining that was a wrong message, now I know in my car 3 bars means empty tank .2- It showed on the dashboard check the hybrid system instead of saying "vehicle is Out of fuel".
