    Thanks, the parts are new, dealer original. The cooler was removed and I took it to the carwash and took out all the dirt that was inside it, which was quite a lot. It's looks like new.

    :(
    I finished installing all the parts today and the Prius still has the same symptoms.
    It turns on but has no acceleration, even though the motor feels more stable.
    When it is in “Ready Mode” you can see the coolant of the inverter pump working but later on it turns off.
    After several minutes the Prius shuts down.

    New parts installed:
    • Battery 12 V

    • Inverter Coolant Pump

    • SparkPlug

    • Mass Air Flow Sensor

    • EGR Valve

    • Oxygen Sensor
    • Cleaned the EGR Valve Cooler

    • Cleaned Fan Hybrid Battery

    I remember in the status of the Hybrid System on the Display Audio System Screen, before it stopped working, it showed 7 lines in battery symbols. I think it's not a hybrid battery problem.

    Could it be the ECU?
    Is it an electrical failure? Relay?

    You need to read the codes again and realize that everything you listed has nothing to do with a clogged egr or a headgasket issue. This requires you chasing down wires with a DMM to see why there is low to no power going to some of your sensors and a pump.

    Reset the ecu and see what new codes you get.

    The codes are the same one from before. I scanned the code and the same errors from the start pop up, nothing new. Remember the codes are permanent therefore they’ll keep on popping up either way.

    Are there any current or pending codes? Any warning lights on the dash?

    Forgive me if I didn't see it earlier, but what are you using to read trouble codes?

    I used Innova 5210. I put two images for you to see.

    Naw, I don't need to read them again. I saw them and I don't care. For all of those systems to fail, they have to have something in common? And figuring out what that is, is the key.

    The OP has it appears, to have done the exact, same thing the Dealer would have done, at a much lower cost granted. Except they most likely could have cleared the codes for awhile? So you roll out the door happyish, with the car stilling running like crap and the exact same codes reappear?

    So then you take it back to them again. And this time since they just "replaced," all the obvious stuff? They check the "Compression." And they say "Oh you have failing HG."

    Now I don't know as it is not my car. But with a Gen 3, with engine problems? The HG is always suspect? So what the Hey, DVOM away, it cost nothing save for time.

    But if the OP did replace the Spark Plugs, without examining them first? They most likely threw the "real answer to the car's issue, in the trash?"

    Your screenshot of the codes has them all under a "permanent codes" heading. Permanent codes can be left around from different things that happened some time in the past. They are not necessarily helpful for what's going on now.

    Your photo of the dash shows that there are current warning lights. Therefore, there are current codes. I am not sure what is going on with your Innova scan tool; is it possible there is a different tab or selection to see the current and pending codes, not the permanent ones?

    If not, I would try to get access to Techstream, or to someone with Techstream.

    Well you did leave out "The Rest of the story."

    But our 2 Gen just overheated in a "rare for our area, major traffic jam?" I did know "something was up with Battery Temps?"

    The Battery was having "hot issue," when the Air temps were over 95 degrees? Temps were creeping up on the Battery Pack? So per Dr. Prius, app I was aware that something was up?

    But she does not use it and the car, just threw the RTOD, on her! So no codes present when it happened? That I could see at the time?

    She is stuck in town, and Hwy, 50 is jammed. So until the Hwy is clear, I won't know if the car comes home under it's own power or on a "Flat Bed?"

    The Battery Fan is clean, as I had just cleaned it. But did it need to be just cleaned or replaced? I don't know?

    I was "suspicious?" But short trips in high heat, only sit high temp's, just enough to make me wonder? Mid pack mostly.

    At this point, I can do nothing? My better half is likely to have the car "towed off to the dealer?" As I don't have the best record for dealing with "lost causes?"

    But I'll start my own thread, if the Car get's back to me? because I do not have the greatest of records, when it comes to "lost cause's?" So I have to wait to see how and if the car comes home?

    I have an appointment with the dealer for next week. We'll see what they say. It would be ideal to use this Techstream Software, but I am using the Apple platform, unfortunately I do not have Windows 10 to install it. Thanks...

    Toyota has to take responsibility for its design error in the event that water leaks and goes directly to the 12V battery.
    The example is that where the water falls you can see the rust stain. Cleaning the fan of the hybrid battery where the screws that hold the fan are also full of rust. The other areas look like new. It is a serious mistake that can have serious consequences. Every time I go to wash the car I have to dry the battery area.

    Look on YouTube and you will see dozens of videos of people looking for a solution to this problem using silicone to seal the possible areas where the water enters. Is it not dangerous that where the batteries are that store electricity, water falls on it?

    My problem comes because it was raining, the water leaked and caused a short circuit.
    Is it necessary for the car to blow up, the car to catch fire, and for there to be human losses for them to change their mentality and assume responsibilities?

    I understand that, but you made a point that Toyota had taken responsibility for it and I want to know which actual incident caused Toyota to take responsibility.

    I didn't mean to specify that Toyota had to take responsibility with MY case, but with the leaking problem in other generation 3 Toyota. In general, not specifically me only.

    If you clear it then they are not permanent. You have to reset the ecu.

    I got the Prius from the dealer and this is the diagnosis:

    2.20 diag for hybrid light on found codes for cam sensor high input and circuit codes also code for hybrid battery fan found blown fuse in engine bay fuse box for fan replaced fuse also found pin bent over in fuse box causing cam codes adjusted pin fit and codes cleared and did not return.

    After driving it for about 10 min, the hybrid signal came again.

    :(
