2011 Prius Died on Freeway - Check Hybrid System

probably drained the traction battery

 

did the dash fill with trouble lights?

have you had the ipm module replaced on the recall?

 

It could be a number of things. If the triangle is yellow, you probably have battery code P0A0F: Engine failed to start. However, that is a very vague error code and this may be associated with an engine error code too. Assuming this to be the case, and assuming you already had an OBDII tool with Dr. Prius, clearing the battery code will do nothing unless the engine code is cleared beforehand. I've been doing a lot of research on the water pump because mine is beginning to fail. If the water pump drops below a certain RPM even for just a second, the computer will shut down the engine and give the code P261B which then triggers the P0A0F.

I'm not saying that this is certainly the cause, it's just one possibility that I'm aware of. Hopefully, whatever it is isn't any more complicated than that.

 

maybe inverter pump

 

maybe a wire came loose in the areas you worked

 

3190 is an engine problem, culd be a number of things. also, there could be other codes if the correct reader isn't used.
fuel pump is sometimes a problem, egr/intake manifold/throttle body are another possibility

 

Watch that hybrid battery, any attempt to start your car will deplete your battery...mine turn out to be a fuel pump problem

The engine probably is not idling it is probably attempting to start off the hybrid battery. I picked up my Prius with a p3190 code. I did the following
cleaned the Throttle body
Added 5 gallons of fuel do to the gauge only had one bar
Banged on the fuel tank while starting (Chevy trick Chevy fuel pumps fail often)

I did all of the above items on one start attempt and the vehicle started.
I got lucky I guess I have put 25,000 miles on the vehicle and had no further problems.

Again the best thing would be to hook up test equipment because you do not Want to run the hybrid battery down. You could damage the battery or at the very minimum have to grid charge it

 

Because all P3 codes are "jointly defined", it's possible that "fuel air metering" might be the right fortune cookie for a P3190 code in some other car. In a Prius, the fortune cookie for that code is just "poor engine power", and what the code means is there was a period when the engine was running, not starting, above a certain RPM, and producing less than 20% of the expected torque for the conditions. So, running very poorly.

It's not really a code that's vague—at least, "hey, the engine was producing less than 20% of the torque it should have" is a pretty specific and clear thing to say—but of course an engine can have lots of different reasons for that to happen. Those just have to be checked and ruled out the way any mechanic with a poorly-running, underpowered engine would have to.
