Prius (2004-09) :: Red Triangle, Exclamation, VSC And Check Engine Lights Came On
When i was driving my 2005 Toyota Prius the Red Triangle, the ((!)) light, the vsc light, and the check engine light came on. I let it sit for sixteen hours without driving it and everything went back to normal. Three days later i was driving and the same lights came on. I let it sit again for sixteen hours without driving and it was still there.
When i was driving i recognized there was a terrible lag, and if i was driving for awhile it took me about one minute to get up to 45 miles an hour. It felt like i was driving in first gear or something.
I also noticed if i had the Heating and air conditioning off that hot air would pump from my back right, which is the seat behind the passenger, that vent was blasting out hot air.
I took it in to toyota and they said the water pump was bad So they replaced it, after replacing it more codes came up and one of them told them to replace the Hybrid Battery Pack which is 3,419 dollars.
I Drove it out of there today thinking that some of the problem was fixed with the lagging of the acceleration and the heating coming from the vents but it was not. I was reading online and everything pointed to the inverter pump where the engine is not being properly cooled, which would explain the excessive heat and the lagging. They claim it still is the battery, but i was watching the battery on the dashboard navigation system and it seems to be driving and recharging fine.
Prius (2004-09) :: 2008 - Red Triangle With Exclamation Mark / Check Engine Light Turned On
This morning I started my 2008 Prius (approx. 31k miles) and found the big red triangle with an exclamation mark and check engine light turned on.
I drove my car <1 mile to a smog check station where they ran a diagnostic on it and came back with the P0A9C code.
A quick internet search turns up that this is "HYBRID BATTERY TEMPERATURE SENSOR "A" RANGE/PERFORMANCE."
Prius (Gen 2) :: 2007 - Red Triangle With Exclamation Came Up With Check Engine / MPG Went Down
I'm at 138,000 miles on my Prius, just got oil changed, 12v replaced in 2014, water pump replaced in 2015. I
I've noticed over the past couple days the mpg has gone down from 39 to 36. Yesterday I was 25 away from my work at gas station and when I pulled out a red triangle w/ exclamation came up along with check engine, VSC and orange exclamation with circle around it. I drove to my work and it didn't seem like performance was different.
When I got to work I turned it off and back on and all lights were still lit. After my shift I went to leave and it was same thing. When I went to reverse it felt like a tug, I pulled about half way out then pulled back in cause I didn't want to get stranded.

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.
Prius (Gen 2) :: Red Triangle With Exclamation Mark And Check Engine Lights Popped On
I've got a 2009 Prius with 67k miles on it. The car has a salvage title, but has given me over 20k+ worry free miles. The past few days the car has been acting a bit odd (i'm not sure if these are related or not but I figured I'd just throw it out there as well).... The right front headlight has been on the fritz as well as the wireless door opener has been working sparsely (sometime it wont lock, sometimes it will). I just ran the test to make sure teh 12V battery was okay, and all of the voltages came back in the "normal" range.

My wife's Prius now has the check engine light, the orange triangle, and the car with the exclamation point lit up. It only has 96,000 miles and hasn't been in a wreck that we know of. I've read that it has to do with the HV ECU, but I don't know much more about it. Is there any chance it's just a loose cable or something simple? It doesn't seem like her car should already be having so many extensive problems all at once. We haven't had any in the past, except the car with the exclamation point came on for a few days and then went away on its own.
Codes: P1636, P3106, P3002, P3006. It's a 2002 Prius
Prius (2010-12) :: Check Hybrid System / Yellow Triangle With Exclamation Mark Came On
Yesterday, started it up, began backing down the driveway, controlling speed with a little pressure on the brake. There was momentary weirdness, like the brakes had sort-of let go, then gripped again. And then got the warning "CHECK HYBRID SYSTEM" and a yellow triangle (inverted?) with exclamation mark.
I tried maybe 3 restarts, but the warning persisted. Phoned the dealership, booked-up Saturday, but they said they'd (commendably) squeeze it in. So we brought it in, when they eventually got to it they read the codes, cleared them, test drive, said it appeared the computer(s) "lost contact" momentarily, and it seemed ok.
I got in and started driving home, down the back lane first. Car started making a VERY strange buzzing sound, coming from under the hood. By the end of the lane I decided I better circle back to the dealership, pulled in at the curb in front, left it running and raised the hood, the hood support rod was loose, laying over the engine, doing a dance.

Prius (2004-09) :: Low Oil - Red Triangle With Exclamation Point
My Prius has about 145K miles on it and use it on a daily 130 mi round trip commute. Recently, a I got a Red Triangle w/ Exclamation Point and the displayed showed "Problem". I took the car to the dealership and they stated the problem was caused from a low oil level. The dealership changed the oil and I was good to go. 3k miles later, I got the same error and noticed my oil level was low once again. It seems that my Prius is burning oil at rate of 1 quart per 2500 miles driven. What can be causing this? Are there any remedies I can try before changing out the piston rings?
View 19 RepliesPrius (2004-09) :: Red Triangle And Little Car With Exclamation Point On MFD
I am getting the red triangle and the little car with exclimation point on the MFD. Interestingly all of the amber lights are on and the brake light is on BUT the parking brake is not set.
Here is what happened --my hybrid battery died a few weeks ago so I ordered a replacement through Summit Racing (Dorman Battery). The car started and drove but I had to rest codes to keep it alive (just to get it home). Last moved it 3 weeks ago and removed the old battery.
So long story short -- while I was waiting for the new battery I repaired some other issues -- BTW I am not new to this, I have the tools and have done these repairs on conventional cars many times.
1. Leaking axle seals -- replaced L and R seals
2. replaced L and R half axles (drivers side was rough so replaced both)
3. Found drivers side wheel bearing to be rough so replaced L and R hubs
4. Replaced L and R struts and strut mounts.
5. Drained and refilled trans axle with Toyota W (TF) 4 qts
6. Installed new 12v battery (currently producing 13.4v)
7. Replaced rear struts.
8. Replaced L and R front rotors and shoes -- they were off anyway so why not. No loss of fluid!
9. Removed and cleaned most interior parts -- door panels, seats etc...
Installed new HV battery and fired her up to the usual wheezing, whining and clicking sounds. But NO engine -- just the triangle -- problem statement and and the other above issues.
Checked the following -- inverter pump is circulating nicely, though maybe battery electronics -- so I placed the old battery back in (it was started with the old one 3 weeks ago) -- nope same issue so not those electronics. Traced all wires, plugs and connectors related to hybrid system -- all seem to be in place.
Prius (2004-09) :: Triangle Exclamation With Faded Odometer
I have recently baught a 2009 prius 2 from a 3rd party and am facing an problem with my car from last week. The problem was very random earlier and now it is happening more frequently.
When i start the Car, a red exclamation mark appears in a red triangle and the intensity of odometer light is very less. Some times i notice a car making a beep sound when i opne the car front driver door to get out of the car.
Prius (2004-09) :: Red Triangle With Exclamation Point When Turned Right At 20 Mph
The triangle comes on momentary for the past week. It first occurred when I turned right at 20 mph. The next time was during a sweeping left turn. Off and on with turns left and right. the last few times it was longer in different situations and I could read the LCD display where is said "PROBLEM".
The local dealer said check brake fluid and open and close all doors. Since it is more frequent I called my mechanic and he thinks it could be door sensors that have built up junk. The dealership does not think it is a safety issue and without any lights on their analyzer could not pull any codes.
Prius (2004-09) :: 2008 - Check Engine Light / Red Exclamation Mark - 12V Battery OK
I've been using my prius 2008 very smoothly till today. It was 100F+ in Austin and very hot. The car, suddenly lit up all the warning lights: Engine, Red Exclamation, Hybrid, and brake lights. The brakes kept beeping on both sides. I also heard an engine noise that is quite uncommon for prius. I stopped the car in a parking lot.
I came back in an hour and tried to start the car. I only saw 2 lights now: Red Exclamation, and Engine check. It might some "click" noise when I started, and after that it was fine. I drove for a while and everything was fine but the 2 warning lights were still on. I tried starting and stopping few times. I did experience the clicks (1-2) and the engine noise. The engine noise lasted 15-30 seconds and then it was back to normal.
I followed the youtube video to look up the diagnostics (Display pressed + lights on/off 3 times) to check the 12V battery. It read 13.8 V. I recently had an oil change at Toyota dealership less than 500 miles back. So I am baffled at this point. I have about ~60K miles and it's a 2008 model. So if it's a hybrid battery issue, I am covered.
Prius (2004-09) :: VCS - Red / Yellow Exclamation And Check Engine Lights All Suddenly Turned On
While my car was idling in a CVS parking lot, the VCS, Red Exclamation in a triangle, Yellow Exclamation in a circle and the check engine lights all suddenly turned on.
In reading the forums, it seems the two most likely issues would either be the inverter pump (which I had replaced as part of the recall, and I see the fluid moving in the reservoir), or possibly a bad 12v battery (which I had replaced last year with the forum recommended Optima Yellow Top).
I checked for error codes, and there were numerous ones there at first, but I think that might have been related to the old 12v battery dying (I never reset after that). I cleared the codes, and no new codes are generating.
Prius (2001-03) :: Engine Light And Triangle Exclamation Point Is On
I am getting a 3006,3011,3015 code from my 2001 prius. The car only has 56k miles on it but sat for 8 months without starting or unplugging the batteries. I am wondering if i need to replace bank 1 and 5 on the battery to get the engine light off? The car runs fine and drives great but engine light is on and the triangle exclamation point is on but that's it for lights. What do i need to do? Replace battery altogether? recharge the effected banks?

I have a 2007 Toyota prius base model, it has 49,845 miles. Today i got in, pressed the bake, pressed the on button, and the Red Triangle appeared with yellow exclamation point in a circle, and on the lcd monitor it shows that there is a problem and a little icon of a car with an exclamation point on it.
The car drives and runs normal, fuel mileage seems to be the same, everything looks normal except the lights. One thing I tried to do: I took off the battery clamp and i put it back on, the warning lights were gone, but as soon as the engine kicked in the same warning lights came on.
Prius (2004-09) :: 2006 - Red Triangle With Exclamation Point Staying On
I have the red triangle with the exclamation point in it. What it can be? I have a 2006 Prius. It still seems to drive ok. I have parked it though and have an apt Monday morning at Toyota. (They didn't have a Prius tech in today) When I first noticed the light it would come on and go away. Now it's staying on.
View 19 RepliesPrius (2004-09) :: Red Triangle With Exclamation Point When Turn Power On
I have a 2008 Prius, with SKS and Nav, and 103,000 miles on the odometer. I bought it from the original owner in 2010. So far it has been trouble free, with just oil changes and scheduled maintenance.
When I turn power on, I get a red triangle with exclamation point. Also a row of yellow indicator lights. Also along the top of the LCD display there is a red car shape with an exclamation point on it.
I followed the procedure for checking the voltage of the 12v battery using the diagnostic screens, using the procedure at weird-stuff-happening-mpgs-dropping-test-the-battery.73400/and I got 11.8 volts.
Since it seemed likely that my problem is related to the (original OEM) 12v battery, which is now 6 years old, I took my handy jump-start battery thing (see photo below) and attached its red alligator clip to the positive post under the hood, and the black clip to the frame. I hoped that would allow me to start the car, but it did not start. The error lights on the dash were unchanged.
Question 1. Does the fact that the symptoms remain the same after I have connected my jump-start battery mean that the problem I'm having is NOT my 12v battery?
I then hooked up my cheap OBDII code scanner (see photo below) and checked for codes. It found none.
Question 2. Does the OBDII scanner not finding any codes have any importance? When people write about having their car towed to the dealer and having error codes read there, does that refer to OBDII codes, or are they referring to some other type of codes that can only be read by a dealer?
While I was in the diagnostic screens, I found three screens of error codes. The screens are called DSP-AMP, EMV, and NAVI. See 3 photos below.
Question 3. Do these error codes have significance?
