Prius (Gen 2) :: 2005 - Triangle And Engine Icons Warning Lights Came On
Jun 11, 2010
Bought a new Prius in 2005. In April 2010 (157,000km / 98000m) the triangle and engine icons warning lights came on. After about two weeks in the workshop, I was informed that the main battery went. Two months later (161,000km) the same warning lights came on again. Toyota agents informed me that now it is the water pump not circulating water through the engine. Toyota on its website states that the batteries should last the entire life of the vehicle. Is it possible that battery problem was wrongly diagnosed, and, that in fact, it was the water pump giving the problem in the first place?

My 2005 Prius with 116K on it has been having some uneven acceleration lately and today the Triangle warning light, the check engine light and the brake light came on at the same time. I had about 1/2 mile to go, so I proceeded slowly and called the dealership which had performed a routine oil chg two days ago. They said that if the lights weren't flashing then I could drive it. They recommended that I take it to AUTO ZONE and put it on the analyzer. This elicited these codes: P3019: no definition and P0A80: replace Hybrid Battery.
I have an appointment in 2 days and I'm wondering about a salvage HV battery since the car is 7 yrs old and over 116K miles.

I own a 2005 Prius with 233K miles. I got the terrible red triangle of death and several other warning lights. Had the codes checked out at Toyota and confirmed a bad HV battery. I am kinda handy and I replaced it myself. No big job, it took about two hours, most of which was spent removing the interior panels, etc. Test drove the car and all looked well. Thirty or so miles later, BAMMM, lots of warning lights. At this point I took it to my mechanic to have it checked out. They found nothing you wouldn't expect when you've disconnected the two batteries.
They cleared the codes and off I went. Again about thirty miles out the lights went on again. Back to the garage once again. What they found was a corroded connector running to the fan, located under the rain gutter of the hatch, passenger side. Hmmm, how'd that get corroded?? Two years ago I remember drain the sump where the spare's located of 6 inches of water, how'd that get in there??? My mechanic confirmed he has seen that before in the Prius. So now I am wondering, did the initial battery fail because the fan may have failed??? Perhaps we need a warning light.....

2009 Prius w/ 29,750 mi [Maint Req Light came on at ~28,000 mi]..
I am getting a Master Warning Light (triangle), a Hybrid System Warning icon, a VSC light, a (red) Brake Warning icon and a Check Engine icon. When the car starts, the A/C is fine but quickly loses cooling output especially with full throttle. regardless of manual or auto setting. Throttle feels a bit spongy and slightly unresponsive.
4 blue bars on charge and everything else appears OK.

I was driving last night and my car Triangle Warning Light and Check Engine Light Went on along with on the nav screen a car with a ! mark in it came on. On The info screen the battery level was changing fast from fully charged to just about empty. The car lost almost all power going about 42 miles an hour. I was able to pull to the side and i waited 10 minutes then tried to turn the car on again. I was able to drive home and the warning lights were still on but at least my car had power. What could possible be wrong?

This afternoon, after driving about 150 miles, I came home and shut off my 2001 Prius. It was sitting for about 20 minutes before I turned it back on to drive off. Almost immediately, the hybrid warning light came on on the MFD, the red exclamation mark light illuminated, as well as the check engine light, and the motor shut off. I popped the hood, and could hear a high pitched squeal coming from near the inverter. I called my dealer to ask the service department what I should do, and they just told me to bring it in and they will take a look at it. I live over an hour away, so I don't want to bring it there if I can avoid it. I then shut it off and let it sit for a few hours.
After reading about the possibility of the auxiliary battery being bad, I went and turned the Prius on, and then shut it off several times to reset the hybrid warning light (I had to do so in order to access the aux battery information through the MFD). It turned on without incident, and shut off fine, and after being reset the hybrid warning light shut off, as well as the red triangle light. Then, I went through the process of pulling up the battery voltage information through the MFD.
With the car off, and the lights and fans off, the battery voltage read about 10.0-10.5 V. With the lights and fan on, the voltage dropped to about 9.5 V. After getting those readings, I drove it down the road a little ways, just going about 20 mph. It seemed to work fine. The check engine light is still illuminated. With the motor running, the voltage reading was 13.2 V, and then when I got back from my test drive and shut it off, the voltage hovered at 10.6 V with the lights and fan on.

While driving to work I received the red triangle of death and multiple other icons on my dashboard. After a few minutes my AC sputtered off. After a few minutes it came back on. This occurred off and on the duration of my drive. I pulled the codes and had P0A93, P3193, C1241, C1313, C1377 come up. The fluid in the pump for the inverter is not moving when the vehicle is turned on.

Yes, they are all on. I have the red triangle, the check engine, the brake, and the vsc lights on. I put in a new high voltage battery this past summer so what now?

Last night I was driving my 2005 Prius in a light rain. I had only been driving for about 5 minutes or so on the freeway. The check engine light and the big red triangle came on. It was a couple of miles before I could get off the freeway, and by the time I could get to the exit ramp, the car at times was starting to race the ice. It was beginning to feel like it was slipping the "transmission" and I felt fortunate to get it off the road. I coasted into a convenience store and parked it. My scan gauge showed me a code of POA3F. I have discovered that this is the Drive Motor 'A' position sensor circuit. What does this all mean? Is this going to be an expensive fix? After letting the car set for a while and a few phone calls later, I attempted to start and put the car in gear. It would only let me put it in neutral. Is there any chance at all that my problem could be less than major?

My car (2006 Prius with 250k miles) was operating normally all day today. Still getting very good mileage around 52 mpg on average. Then abruptly, the big red triangle and few other yellow warning lights (check engine, VSC, and an indicator with exclamation mark in the middle) showed up while the car was moving around 20 mph.
Now, the car does not have much power and it was very difficult to speed up or going uphill. Turned the engine off and then back on. The symptoms still persist. The battery indicator was at only 1 bar. Let the engine run for a while and the battery indicator went to 3 or 4 bars. Turned the car off and then back on, the battery indicator went back to 1 bar immediately. Also the battery fan was running at high speed, even through I have just started driving for about 5 minutes.
Will do the following tomorrow:
(1) check 12v battery,
(2) use Torque SW to see if HV battery has proper values, and
(3) read diagnostic codes.

I have a 2001 Prius with 150k on it. It has been giving me the triangle warning light and the car ! warning light. I can start the car and drive it, but sometimes when I press the accelerator the gas engine just dies and will not kick back in, unless I stop, turn off the car and restart it. (Issue seems to occur more in hot weather, could be a coincidence) When I start it the engine will run rough and shutter for less than a min, and then run normally.

My 2005 Prius has about 141000 miles on it. The red triangle exclamation point comes on the dash and a yellow exclamation comes on the LCD 1st and then a 2nd yellow symbol comes on the LCD. The problem happens once or twice a day. It seems to start, run, and drive just fine. I do restore antique tractors and I am pretty good with computers and I have some pretty good mechanical know how. Attached are pictures of the lights.

I'm not sure if this is a general FWD car problem or a Prius problem but a week ago I noticed a loud, and reasonably pure, tone that seems to be coming from the front of my '05 Prius at highway speed I don't believe it is tire, alignment, or road noise The car knows that something is wrong because it occationally throws some error lights but refuses to reveal the specific code My current thought is drive shaft, axle, CV joint, or similar but I don't know if that can turn on the error lights Any thoughts? Could I have two independent issues?
The car has 157k miles and was in two minor accidents before I got it One required a rear bumper replacement, the other they had to pop out a dent from the front driver's side quarter panel The records do not indicate that any other parts were damaged I have owned the car for 25k miles
Error lights: A few days after the noise started and 30 minutes into my morning commute while driving at highway speed up a hill (20kW from the ICE) I got the big red triangle of doom, ((!)), VSC, and the mark on the red car on the MFD. Aside from the lights the car appeared to drive normally I checked the voltage on the MFD less than a minute after the lights came on and it showed 14.1V The MIL light was not lit, and the Torque app on my android was not able to pull a DTC but was able to clear the error and consequently turn off the warning lights
The next day the same warning lights popped up again and at the end of the commute I used a paperclip to connect pin 4 and 13 on the OBD port in an attempt to read the code When I turned the car on with the two pins shorted the red triangle lit but the ABS, ((!)), and VSC lights all blinked at 2 Hz indicating their systems were normal After turning the car on and off four times the red triangle went away
The error lights have now popped up four times, each time after more than 30 minutes of driving I have also had several trips longer than an hour where the lights did not come on

I have a 2005 Prius with 107K miles which I had taken off the road for about 2 months. Car ran fine previously. I just replaced the old 12v Battery with a new Optima replacement battery, changed the oil and filter, and have 1/3 tank of gas. Inserted the key into the slot, foot on brake, pressed the Power button, and, just about every warning indicator light is On (Brake, Red Triangle, Check Engine, (!), ABS, VSC, Traction Control) and the yellow exclamation mark with "Problem" message appears for a second on the Display, then a Red Car (!) appears in the upper left-hand corner of the display. Car will Not go into Drive or Reverse, and engine will not run, even when gas pedal depressed. Am I doing something wrong, or did I let the car sit too long?

There's an ad for a car quite far away from me and one of the photos shows the dash lit up like a Christmas tree. Is this normal during power-up or is it normal when there's something quite wrong?! There is no red triangle of doom shown; I'm unsure if that might be out of shot though. Car is quite high mileage with just over 270,000 km on the clock and is from 2006.

I was driving down the highway today and the brakes light (!), vsc, and master red triangle warning lights came on, along with a car with an ! in it on the main display screen. There is no noticeable difference in noise, mpg, or breaking performance. From reading through previous forums a bad 12v battery seems to be a common problem. Mine was replaced ~8 months ago. About 2 weeks ago the serpentine belt snapped and the car was drove ~2 miles to my home where I replaced it along with the bad water pump and also the thermostat. Could that have caused my current problem. 130k miles on the car...

I have a 2006 Prius with 186,000 miles. The engine developed a knock. I swaped the engine with one from a junk yard. The swap went well. I reconnected the HV battery and the 12v battery. When I tried to start the car I recieve the red triangle with many other dash displays and (!) over the car in the upper left corner of the system screen. I checked for codes with a code scanner, all I can see is $7ea and $7eb. When I clear them the (!) disapears for about 5 seconds and the word problem displays and then tha(!) comes back. The 12v battery reads 12.4 volts.

I bought a 2006 Prius. A few days ago the car was driving along just fine when the red triangle appeared together with the 'problem' message followed by the red oil warning displaying in the top left corner of the screen. A few seconds later, the yellow engine light lit up and I drove the remaining mile or so back home (very slowly and carefully). I should point out that the car didn't drive any differently after these warnings appeared and I haven't noticed any strange sounds or anything like that.
I've been out to the car on a few occasions since. It goes into ready mode just fine and drives perfectly in EV mode. The triangle and oil warning reappear shortly after the engine cuts in every time it's started. The hybrid battery charges and discharges on the display when it's left at idle as normal. A friend of mine has a cheap and cheerful diagnostic machine that he brought over and that pulled the P0340 code which relates to the camshaft position sensor. That sensor has been replaced for a brand new one and the fault codes cleared but the code is still showing.

I have a 2007 prius. I was driving home all a sudden I get a big red triangle warning and the engine logo came on. On the display screen its show a logo of the car at the corner in red with exclamation mark. I use the car obdII scanner but no error code came up. I decide to check the engine oil. When I remove the cap, I notice inside the engine it look weird like a gold color and some blackish. The engine cap inside look like it have stains on it too. The hole where you pour the motor oil down I notice that piece inside don't go down for the funnel to stick in. I attach some pictures. I have no clue what's wrong with it and I don't wanna drive it to make it worse. The prius only have 90k miles on it.

2010 Prius with 85k miles. Went to start car and here is what I get. All lights on dash come on including emergency icons. When I depress brake to shift into gear lights on dash go dim but not out. Car does not go into gear and neither does it show it going into gear on display. Heater was on and I tried to shut off the fan and again no response. Very difficult to get it to shut off. Pushed off 3 or 4 times and it finally responded. Been cold here in the teens and car has not been used for 3 or 4 days. Everything has been fine up to this point. No problems with anything.
