Prius (2004-09) :: Red Triangle Warning After Engine Swap
Oct 31, 2010
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 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?

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.

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?

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.

Stopped at ATM when heard a thump under seat and all the above appeared on control panel. Waiting on computer code reader to test vehicle. Any clues to what all this means. Vehicle 2006 with 101K. Recent service as scheduled with coolant and inverter coolant and belt replacement done. No other issues to date with vehicle.

My wife and I own a 2006 Toyota Prius that we bought used 2 years ago. a couple of days ago, the master warning light (red triangle exclamation point) and check engine light came on. I took it into the dealer and of course, our hybrid battery was dead - battery and a new ECU required.
Our car is at 99,000 and 32 days out of warranty. Went down the road to atlanta hybrid repair. they were incredibly nice, and said that my computer was fine, but the battery would need to be replaced.

The red triangle warning light on our 2004 came on and went away again It has 100k miles If I take it to the dealer can they pull some codes and figure out why it turned on We have to drive the car to 600 miles for the upcoming weekend and I don't want to be stranded on the side of the road The car has 103,000 miles We just replaced the 12v battery so I know that is OK
I also saw the following things to check. Is there anything else we should check?
1 - Are any warning lights on besides the red triangle? For example, the red BRAKE light, the amber ABS and VSC lights, or the amber circular icon?
2 - Did you check the brake fluid level? If low, buy a new container of DOT3 brake fluid and replenish as needed This fluid will dissolve paint, so do not spill it
3 - While you are at it, check the radiator and inverter coolant levels by looking at the translucent reservoirs behind the radiator and next to the inverter If low, fill with Toyota Super Long Life Coolant

I took my car to the dealership because it had the red Triangle ! wanrnning on the dash and the red car ! warning on the display panel. They told me the code was P0A82 "hybrid battery pack cooling fan 1 performance / Stuck off" but it was actually working at the time the mechanic looked at it.
He said it would probably need to be replaced anyways so they wanted to replace it. I told them I would wait, so they cleared the code for me. I read a lot of posts of people having the same problem and they fixed it by cleaning the fan. My fan was a little dirty, but not bad at all. Is there a quick way to see if the cleaning fixed the problem?

I have an 07 and replaced the HV battery. Before swapping battery, I had Red Triangle, (!), VSC, Check Engine (took car to dealer who diagnosed it as needing HV battery). Now new battery is in but error-icons remain. The LCD display shows battery as more that half-charged. I connected an old Actron ODB2 scanner (circa 2000), but it doesn't Read any codes and doesn't Erase the codes causing the problem.

This morning I went out to warm my car up for a few minutes because it has been so cold and when I started it the red triangle warning light stayed on and the consumption screen said "problem" across the top with a little icon in the upper left hand corner that looked similar to a high beam headlight indicator. I turned the car off and started it again wondering if it would clear which it did not. I left it running and went inside to get my child and by the time I came out it had cleared itself.
In typing this I recall that I thought it stayed on a little longer than normal the other day and just ignored it thinking it was still in lamp test mode on initial start up.

About a month ago my 2009 Prius - 35500 miles - started acting up intermittently. When I first start the car I am getting a red warning triangle for just a few seconds and I feel/hear a soft thump under my foot that is on the brake pedal, there is a few second pause - the warning light goes away and the car starts just fine. This does not usually recur until the car has shut off for a few hours or so. I have had the car to my Toyota dealer twice and they could not reproduce the warning light even after it had been sitting all nite. That was about a month ago - and the problem has been very intermittent. Then yesterday we had a pretty cool morning and when I started the car I got the red warning triangle and a Warning on my screen -- something to the effect that "There is a Park and Transmission Lock" - I turned the car off and started again almost immediately - no warning triangle - no warning message. It happened again once this morning.

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?

I have a 2005 Prius with 240,000 miles. About 4 months ago the triangle warning symbol appeared. A friend and I decided to pull the big battery out of the car and find the bad cells. We did that, replace two and the car worked fine for 4 months. The triangle warning has returned. We have done several things but the triangle remains. We pulled the big battery out and checked all of the cells. We replaced one that was probably OK. The latest reading was 8 volts on cells all but one at 7.9. We cleaned all of the bus contacts. We went into the maintenance mode on the MFD and found the aux battery to be 12.6 volts and under load it dropped to 11.8 with the lights on.
The aux battery went up to 14.1 volts with the car on. The inverter cooling fluid has movement and there is a slight humming which I believe to be the inverter pump running. The inverter fluid was topped off. The MFD showed the battery bars start at about three fourths full, drop down to one bar. With the engine running the battery bars climbed to the top purple. The engine turned off and the bars continued to climb to all green. All of this occurred in about 3 minutes while the car was parked. There were codes on the MFD while in maintenance mode. I understand that these codes are for the navigation system and the audio system.

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?

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?

I've seen this a couple times but always made it home with the Red Triangle and VSC warning. A year ago, I blamed it on the OEM 12 volt battery and eventually replaced it with a Optima Yellow Top. No more problem until today. Day time driving with my Plug-in Supply 10k rechargeable conversion performing normally. City driving raining but normal Western WA conditions. Red Triangle and VSC warning. Other systems operating normal.
I knew, from previous experience that the Prius operating systems would continue to work only until I turned it off. I did turn off the Plug-in Supply controller to isolate that system and observed that the OEM traction battery was at a fairly high state of charge and the ICE was still providing the normal amount of assist to the traction battery through normal street and driving conditions.
I should have driven the 20 + miles to get home, even with the Red Triangle warning. I had done that in the past with the old OEM 12v battery. But I needed gas and went to a station and turned off the system ICE out of habit. Sure enough, the system wouldn't go back into Ready but would go from Park to Neutral. Since it was rain hard now, and I was calling my road service, I ask for a Flat Deck Tow home rather than a jump start.
As soon as I got off the tow truck I put my battery charger on the Yellow Top and it only read 11.7 volts. It's still on charge now. Now I'm wondering why the power conversion system wasn't charging the 12 volt battery or is my 1 year old Optima bad?? Or is there something about my driving conditions/plug-in conversion that is effecting the charge of this battery. I did a 2400 mile road trip to So. Calif and back to WA without any problems. Car has just 98169 miles right now. About 10k miles on the Plug-in Supply conversion.

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.
