Prius (2010-12) :: Check Engine Light P0A93 - Hybrid Overheat Alerts
Jul 9, 2015
Gen3 Prius. Once it turned 100k miles I took it in for an inverter coolant change per the maintenance schedule. The dealer charged $109 for this and the car had absolutely no issues prior. Got the coolant changed on 7/23 and then drove it short distances in town for two weeks with no issues. Once I drove it on weekend longer road trip got a check engine light P0A93 "inverter A cooling system performance". Shortly there after started getting hybrid overheat alerts and pulled over to let it cool.
I checked the inverter coolant reservoir and it was still above full. After letting things cool, I turned it back on and listened to the water pump. Seemed to be running fine, heard it clearly with my ear up to a long screw driver, touching the pump. Noticed that the hose leading to the pump was vibrating but the return hose out of the inverted was not. Also no turbulence in the reservoir. My guess is that they didn't bleed air out of the system.

New 2015 PIP, got it 2 months ago, and it drove fine till Thursday, when this message came up. I believe I first got a "Charge interrupted due to malfunction" and then the dreaded "Check Hybrid System, Stop the vehicle in a safe place." alert with all the engine lights on.
Took it to the dealer and they charge it up, cleared the message, and gave it back. They told me it was because I shared the car's outlet with something else, and then threatened to charge me money if I came back because it was my fault. Took it home, charged it exactly the way they told me to, and this morning the error message came back up. Going to take it in to the dealer tomorrow.

My 2007 just came due for an oil change a week ago (Maint Reqd stays on), not that it matters. Yesterday the Red triangle of death, Check Engine, and brake warning lights came on. We drove another 15 minutes (city) without incident. When I turned the car back on the brake warning was off (and has stayed off) but now the Info Display has the red Hybrid System Warning Light also showing, along with Mr. Triangle and Check Engine.
This morning Autozone read out the P0A93 (confirmed) and C1300 (current) codes for me. With the car "Ready", I can see fluid movement in the inverter coolant reservoir (not sure it qualifies as "turbulence") and feel vibration in the line connected to the pump which is humming so quietly. The 12V battery shows 12.5V with the car off and 13.5V with the car on. Does this mean the inverter is still operating? (I read the P0A93 code is supposed to shut it down.)
I did find the ICE coolant reservoir dry and refilled it with SLLC. There looks to be a small leak in the water pump, but I'll deal with that later.

Last summer I had a catastrophic experience on a family vacation when my wife's 2012 Prius overheated on the highway and lost power. The dealer that we limped into kept it for a week and couldn't find any concrete problem, except to say that since it was a salvage vehicle rebuilt without Toyota brand parts, that all of the cooling system would need to be replaced. I waited until we barely made it home and had my mechanic replace the inverter pump.
Since then the "hybrid system overheat" warning light comes on regularly, especially when driving up a long climb, even in moderate weather. There are no codes. Is it possible that there is air in the lines? My mechanic says that it feels like the inverter pump is working, tho I don't see turbulence in ready mode. A link to bleeding the air?

I have a 2013 Prius Persona with about 5,300 miles on the vehicle. Just recently had the 5,000 mile service taken care of at a local toyota dealership. The very next day I tried to start my vehicle with no prevail. My instrument panel indicates "check hybrid system" (!) the car will not start, nor will it shift into drive or reverse, only into the neutral position. Made several attempts to turn vehicle on and off and tried to jump start. Still no luck. Had the car towed back to the dealership. Mechanics are still trying to identify the problem. What may be the cause?

So a little over a month ago, I was driving my 2010 Prius (about 42k miles) when the Check Hybrid System light came on. I lost power and my car was stuck on the road, as I was unable to get it into neutral. So I called a tow truck and was towed to my local dealership. The dealership ran some tests, thought it might have been the throttle body. They switched my throttle body with a loaner prius to see if this fixed the problem. The new throttle body worked in my car and my throttle body was put into the loaner and functioned fine. Then they ended up fixing a TSB for the electronics in the car. I was told the problem was resolved and I could pick up the car about a week later.
After picking up the car a week later, before I could even drive away from the dealership, the Check Hybrid System warning came on again. I talked with the service manager and left my car to be fixed again. They checked all the systems and were still unsure what the problem was. Eventually they made sure all the connectors were properly seated and test drove the car and ensured the problem was gone. About two weeks later, I was told the car was fixed and I could pick it up.
After picking up the car, I was still unsure the problem was fixed, but I was told that was all I could do. After having the car, for about a 1.5 weeks I was on the highway. Once again, the check hybrid system light came on and I lost engine power. Luckily, I was able to pull over from the left lane without causing an accident. Once again, I had the car towed to the dealer and now I am waiting to hear back from them.

I was driving, when out of the blue my car went into neutral, and the dashboard lit up. Then all of a sudden the light stayed on "check hybrid system". I pulled over to side of road. AAA towed me.
THIS SHOULD NOT HAPPEN. NO warning.

Check hybrid system light came on and the whole dash lit up like a christmas tree. After i jumpstarted the 12v battery when it died. It was driving fine for about half an hour and all of a sudden the lights came on during acceleration from a stop light.

I have a 10 month (15,000 mile) Prius and the " check hybrid system" warning light came on while driving on the interstate. 17 miles later the car quit running. I had it towed to the local dealer and after taking a looking at it I was told the error code pointed to the water pump (which they plan to replace). Does that make since? Has this been a problem for the Prius IV?

2010 Toyota Prius III with just under 60,000 miles. The car has been serviced at Toyota from day one (by us and by the previous owners) and runs like a champ. Well, did.
Last week while driving home from running errands the Check Hybrid System light came on for my wife. The car was still running so she drove it home for me to look at. I hopped in and noticed the gasoline engine wasn't turning on. I took it for a spin and even when I floored the car the gas engine wouldn't turn on. Since the nearest dealership is 15 highway miles away I knew we weren't going to make it there on electric power so I had it towed.
The Toyota dealership called me the next day saying when they started the car the light was gone and the car ran fine. They did some troubleshooting and found nothing wrong. They said it might have been a glitch and to come get the car. Not even 3 hours later the light turns on again. Again the gasoline engine goes silent, but this time I didn't even make it a mile and the electric power shuts off as well! We coasted to a stop and had to have the car towed again. This happened out of nowhere and could have been a very serious safety situation had it not happened on the road we were on.
This time the Toyota dealership had a little more to say. They said that their diagnosis has determined that the inverter is shot and they will have to order a new one. They said this failure is extremely rare (the service guy I spoke with had never seen this issue).

So my wife was driving our '10 escape xlt and the engine light came on and it displayed the 'check engine' message on the screen. It has 86500 miles and luckily no problems yet. The only thing that has changed was she accidentally put super premium gas in it the other day. The light came on and after she drove it home (about 10-12 miles) and it sat for a few hours and i drove it about 20 miles it randomly went off while it was idling.
I shut it off and let it sit for 20 minutes and then let it idle for a few and it never came back. It has been running ok. We definitely drive it a lot as she works day shift and i work nights. I'm just trying to make sure there's nothing wrong with it. I got a bulletin a while back about the intake getting moisture in it. I didn't know if maybe this could be the beginning of this or something else. This is a whole new territory for me as i consider my 91 f250 'new'

I was curious how you can get rid of an annoying "check hybrid system" dash warning?
Let's just say I know for certain nothing is wrong. It's only cause I accidentally disconnected and reconnected a wire. Just need to reset is all.

I have a 2015 Prius package two. The other day I was taking it in for its 10,000 mile maintenance, and I pulled out a fuse that I connected my DRL lights with the Main power (so the drl lights would be on with the head lights). The car was on and the check hybrid system light came on. The car would not move only stayed in park and neutral. I had Toyota care come pick it up and they said that if there's any issues that the warranty won't cover it. How I can get the warranty to cover any damages if there is any. The tow truck driver said he thought the car Might think it's being stolen because I did unplug the battery for about 15 minutes to try to reset the check hybrid system.

I just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?

I have a problem with my 2002 prius. I was driving home from work when all of a sudden my Hybrid Warning light came on with the check engine light on. On the screen, it gives me a (PS, Battery, and ! ) and the "!" was the one lighting up. The engine was roughing up sounds like it was gonna stop itself so I pulled over to the side and it turned off by itself without me doing anything except to put it on park. Then, i took out my keys and tried restarting it and all i heard was the "Ready" beep but not the engine and it won't move when i step on the pedal. After waiting for 10 mins., i tried restarting it and it worked i drove away and got home safely with all the warning lights i mentioned earlier still on. (Note: i was driving w/ the A/C on because it was hot outside..around 90s, also it was not overheating nor it was any battery problem because all the electrical were working properly.)

My check engine light came on, I took the car to my usual mechanic, and he said the codes returned indicated that two cells in the batter were bad. (I just called to get the codes, but he's out of the office for about 30 minutes on a test drive...)

The engine check light is ON this morning. It said that there are problems for the hybrid system on the display. I sent it to dealer immediately.

So this morning when i started up my car the cel came on. The car seems to be running fine so i decided id try to go to work and hope for the best. Well nothing happened and i made it to work fine, but i noticed i was always regenerating power. My drive is 45 miles all freeway and little traffic most the drive.. ive never had this happen on my drive to work and ive had the car for a year now. Could the hybrid battery be dying? i have a cheap scan tool but that doesnt mean i will get the correct reading...

I own a 2005 prius. It is stock and i recently had the check engine light pop up as well as "problem" when car was started and 2 lights with exclamation point, one on a car and ones in lil brackets. I believe it is called a "hybrid malfunction light". Well one day they all pop up and about 3 days later theyre gone. Only thing i did was fill up the tank, when they came on only 1 bar was left on the tank. My question is should i still take it in to see whats wrong with it? and what could of caused both lights to come on?

Possible hybrid battery failure in my 2004 Prius (96K miles).
Sunday before last, the check engine light, warning triangle, and hybrid warning light came on when I started my car at the grocery store.
Because I was close to home, I drove home and the car functioned completely normally. The next morning, when I started the car, the same warning lights appeared. However, when I tried starting my car with the headlights off (I always leave them on), no warning lights appeared.
I took my car to an independent mechanic. This is their written report:
"Found multiple check engine codes, P3000, sub code 123, V0100 sub code 211/330. These codes are set when high voltage control detects a malfunction in battery pack/ECU assembly. To check battery pack we took vehicle out on a test drive while monitoring the cells in the battery pack. Found that they are all weak and drop fast when battery is put under a load. Code C2318 is a low voltage error/power supply malfunction code with the auxiliary battery. The voltage spec for setting the code is 9.3 volts, this battery is less than 9.2 volts."
In conversation, the mechanic also told me there was significant voltage variation across the cells in the hybrid battery.
I then took my car to the dealer to try to confirm this analysis. They were unable to read any codes because the independent shop apparently cleared them. The dealer was unable/unwilling to do more than read the codes to diagnose the problem. (Indeed, they seemed surprised that the independent mechanic could monitor the cells in the pack.) All they did was to drive the car around some more to see if the check engine light would come on. It did not.
The car has been driven 80 miles since the warning lights last appeared and appears to be behaving normally. From your perspective, does the report from the independent mechanic make sense and is it believable? And is their test under load definitive of a hybrid battery problem? Could the results be affected by the low auxiliary battery? Also, if I do have a hybrid battery problem, what are the chances of being suddenly thrown into limp mode while driving it?
