P3193 and P0A0F code

2007 Prius, lots of miles

ADDED 7 Gallons of GAS by hand from a metered Gasoline bottle.
The engine will not start
The fuel pump sounds to be running when I jump it
I swapped out the fuel relay

The car reports one flashing bar of fuel (incorrectly) As the gas was flowing back onto the ground, it is safe to say it is FULL.

I guess what I want to know is if the gauge sender fails and decides there is no fuel, does the computer shut the motor down and prevent the fuel pump from running?

And so....
If this is the case, unless I find a wiring issue, I will need to replace the gas tank (unless I can get to the sender) I know there are screws around the pump and the pump cannot be removed, but is it possible to get at the sensor sender?

I omitted the other errors, such as replace hybrid battery...that might make mechanic shops salivate, but I have a full set of cell spares...it just got tired as my daughter did not sense the engine had stopped and drained it....any one have a hand crank charger?

 

I believe the primary problem is the engine will not start...the fuel sender has failed. The hybrid battery will charge once the engine runs. Barring that, I can charge the cells if need be

 

It goes into Ready mode sometimes now but fails after an attempt to start the engine, I am afraid the traction battery is too low to turn the engine now, I will have to manually charge it. No maintenance has been recently done. An oil change happened about 2 months ago


This car has 452,000 miles on it. The engine was replaced with a used one, along with the transaxle some 45,000 miles ago. The replacement was required as the old block was eviscerated by the exit of 4 recalcitrant rods (its important to check oil level often...oooops). The hybrid battery was swapped at the same time as it was recently reconditioned.

The trouble codes were omitted so I could avoid all the , "did you put gas in it?" questions:
C1203
C1345
P3193
P0A80
P0A0F.

I was able to get the gas gauge to register a full tank after using the recalibration procedure on the car:
Turn car on and press odo/Trip button until Trip A is is displayed
Turn vehicle off
Keep foot off brake and press power button twice holding down odo button
press and release odo button 3 times, and continue to press it after the last (I guess this means depress 4th time and hold)
odometer displays 6 digits
release and press odo and hold button
odometer displays 5 digits
odometer displays 1 in the middle
Release odo button

Turned vehicle off then back on and it now displays a full tank. As noted, it cannot crank the engine, and I received a new triangle. I will post the newest codes shortly. I would say the traction battery is weak and I am hunting through the pages and youtube for the reconditioning process again. I will recondition the old pack even if I get the car running....trying to avoid the gas tank drop, But, I probably should snag the one on the wrecked prius before I junk it. I put this kind of work into the vehicle as I respect the engineering of a vehicle that often goes beyond 300k miles.

I put gas in the car and on the ground.

 

Quite the mystery. Did Toyota ever release an error code logic diagram? It would clear up these nuances

I did a recalibrate but I like your idea . Now, why has nobody cut into these tanks to tinker? then again...with a bladder in there.... a spark from a tool could lead to an early Fourth display. I suppose you could fill it with water? but, outside the bladder might be quite explosive
