hybrid system failure

Welcome to Prius Chat .

Some questions:

• How many miles on your Prius?
• Did you go to the Toyota dealer to pull the codes?
• Did you pull the codes yourself? If so, what code reader did you use?
• Were there any other codes displayed?
• How much was the inverter reservoir overfilled?
• Any other issues in the cars past?

Keep us posted .

 

Probably not, but the inverter has a lot to with your AC output, the temperature on a healthy inverter is always slightly warm to the touch. If your inverter is getting too hot, your inverter coolant pump may nor be working. Did you try rebooting the car? Otherwise follow Rays advice.

The pump should show slight agitation at top W/O the cap on and in ready.
You can also put your hand on the pump body and see if it’s working, is there air in the system?
Needs to be bled, simple procedure.

 

Engine revving, have you cleaned the air sensor and throat, 134000 that’s getting up there.

 

This is a must maintenace and easy to do.

 

I edited post 5, see, I’ll let others take your code questions, I’m not experienced in that area.

 

While your checking for air in the inverter area, you may as well check the radiator cooling for air and bleed.

 

Last sentence. Very possible, the dealer should have automatically checked the pump and if necessary bleed the air out. It’s not a major problem if they filled the jar too full, but, is a sign of poor attention to detail. There is a line on the glass, they should abide by that.

 

Typo, the second one is P0A80. Both refer to a hybrid battery failure. The inverter fluid has nothing to do with battery per se (it doesn't cool the battery). Inverter faults have their own codes.

 

As I said before a simple reboot may restore to ready

 

To add on to the OP’s thread, those will be the generic version and should also have additional codes to help narrow down the issue.

But you’ll need a way or work with the dealer to get better clarity.

Good luck and keep us posted .

 

From autocodes.com:
P3000 TOYOTA Description Based on the malfunction signal received from the battery Electronic Control Unit (ECU), the system alerts the driver and effects fail–safe control. This DTC is output when the State Of Charge (SOC) of the HV battery decreases as a result of leaving the vehicle in the N position, running out of fuel, or malfunction in the HV control system.

As @fotomoto said, the P0A80 is a hybrid battery failure. Has nothing to do with inverter coolant. You should have one or more sub codes telling which battery modules are low.

Some people like to play whack-a-mole replacing just the failed module/s and then replacing other failed ones soon thereafter. It's the cheapest option if you don't mind fixing your car over and over and possibly getting stranded at bad times in bad places. A Prolong grid charger helps the rebuilt battery last a lot longer but is unlikely to resurrect one that has a failed module until you replace that module. Used, but not as old as yours batteries are available, but the best fix is a new battery.

 

You might want to do a search for them here on PC before investing in their services. Rebuilts do not generally last very long.
