I have around 68k miles on my 2009 Prius and just got a CEL, the Red Triangle with an exclamation point, an intermittently occurring VSC light, and an intermittently occurring yellow circle with an exclamation point on the upper dash display. I also have a car shaped icon with an exclamation point on my main display (ICE?). My scan tool shows P0093 as the only code.
View 19 RepliesI got red triangle and headlight icon on the screen. I hooked OBD and It gave me error code P1116, I checked all my front, back lights are working fine.
View 19 RepliesI recently purchased a second-hand Prius T4 (2007 model) and I noticed that the red triangle exclamation was showing on the dashboard. Initially, my local mechanic found a P3000 error code and a B1801 error code.
I ran techstream on it just last night and the main errors that came out were:
Current codes:
Srs airbag B1801 - open circuit in driver side circuit
Air conditioner B1421
Transmission control - C2318
History codes:
HV battery - POA84
I also have just found out that this car was in a major collision in 2012. The air bag light is constantly on, along with the red triangle exclamation, on the dashboard. The fuses for the battery fan kit, horn, and air bag needed replacing (I think all three but definitely two of these).
I currently have a 2008 Touring Package 6 with 180k and I am getting weird problems. I am getting the triangle of death, VSC, and yellow ! light. There is no check engine light. On the LCD I am getting the red battery + - icon as well as the car hybrid icon. I scanned it and I am getting a hybrid code P0A09 . All of the maintenance have been kept up and all fluids are perfect. No weird noises and the car is doing 53 mpg. It switches between gas and electric with no problems at all. Symptoms were yesterday with the lights. I cleared the codes and they would come back instantly. Today, I did the same thing and now everything is perfect. I am attaching the pictures of my dashboard lights that were on and the codes I was able to obtain in diagnostic mode.
View 11 RepliesUpon turning on my car and driving a few feet I had the Red Triangle of Death, Yellow VSC, Yellow (!) Indicator, and check engine light and I'm trying to figure out where I should start working on the issue.
The Codes were as Follows:
P3000 (subcode 123)
C0200
C1241
C1300
C1310
C1259
A little history:
About 3 months ago I had an issue with the hybrid battery and replaced a battery cell which stopped all issues. About 2 weeks ago I replaced the coolant inverter pump and until today there has been no errors, CELs, or any negative performance.
This is a Gen II, 2007 prius with almost 200k miles.
Unfortunately I had plans that I could not reschedule and made the drive to the location and drove back. I had serious battery drain and it was almost always at 1 bar of battery, sometime reaching up to 2 bars. There is also the sound of a fan coming from the back seat, which I assume is the HV Battery fan, but it is on regardless of if I have air conditioning or not. A/C is working fine. When I returned home the battery charged almost up to full bars, but when I came to a stop the battery drained in about 10 seconds leaving me with very low power to keep moving. After that whenever I slowed down the teal arrows showing a recharge of the battery were gone and the battery seemed to refuse to recharge.
Steps taken so far:
I topped off my engine coolant in the front reservoir as it seemed a little low, but I didn't add much before it was full. The other reservoir near the engine was just about full and taking off the other cap showed coolant filled to the top.
I tested the 12v battery with my voltmeter which came back reading 12.7.
Driving my 2008 with 189,000 miles on the congested "freeway" the ominous red triangle and the yellow exclamation next to it just lit up. A quick scan of the OBD showed no error codes and good auxiliary battery, engine coolant Temps etc. And good gas mileage, engine vacuum. I had replaced the spark plugs with new iridium two months ago. When I stopped and checked the hybrid converter had good levels and turbulent flow. The oil had been changed a week ago and checked again at lunchtime. Now only the red triangle shows.

View 3 RepliesMy 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 RepliesI 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.
2001 with about 117,000. Just had it in to get the transaxle fluid replaced for preventative measure. Now I'm getting an intermittent triangle/exclamation warning. It seems to go off if I let it sit, mostly. Runs ok for the most part. But when that comes on, it practically limps on very little power.
View 6 RepliesI was driving on the freeway in houston yesterday and it was about 30 degrees. The low temperature light was on... Does it make a difference when it is cold? Why would there be a light to tell u that it is cold outside?
Anyways as I was driving on the freeway the red triangle with an exclamation mark came on and disappeared. Then a minute later it went on again and on the navi screen shows high coolant temperature symbol on it. But then it would turn off right away too so is this normal because I was kind of slowing down on the freeway and the book did say something but I don't think it was an excessive speed or anything.
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.
Check engine light, red triangle with exclamation, and on the monitor a red box with a picture of a car with exclamation came on after changing the rear brakes. I checked the water flow control valve and water pump. Don't know what else to check.
View 3 RepliesI 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.
View 17 RepliesSo at about 147k miles, triangle comes on. It's the icon on the right with the car and exclam! mark through it. Turned off radio. listened to car and I could swear that it was running differently, but it might be in my head (I was kind of freaking). Drove to my Prius guy in the I.E. (20 miles) car seemed to act OK. Was using elec engine when needed and gas engine was fine. Was a bit shocked by how good the car was running but I was sure something sinister was happening and at any minute the car would melt. After 1.5 hours and a 20 mile test drive.
View 9 RepliesI 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.
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.
I replaced one bad module and seemed to run fine for a 3 or 4 miles, but now getting red triangle and a yellow exclamation mark with no codes showing up (using Torque app) and car goes in and out of a weak sputter just like it did before I replaced the bad module. What to do next.

View 1 RepliesI 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?
View 19 RepliesI 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.
