    Hello, when I start the car in the morning, it soon turns off and lights up. Check the hybrid system. After that, there is no movement, the engine is strong, when it warms up, I drive perfectly all day, no problems. When we connected it to the computer, we wrote p0452 code soFuel Pump Tank EVAP Pressure Sensor And could this be related to cleaning? Egr?

    There is a pressure sensor in the EVAP system and obviously there's something wrong with that because you have this code I don't know if that's enough to shut the car off or not but apparently it is because it's shutting off so you might need to look up the whole work up for that code and see what needs to be replaced.

    The evap system code might be a real issue, but not the same real issue that is holding you up.

    With the "check hybrid system", you can probably get a code or codes from the hybrid system. But the scan tool you used might only have shown you codes from the engine control.

    We have a thread that compares a bunch of scan tool options and indicates which ones can get you all codes from the car.
