Prius (Gen 2) :: Check Engine Light And Red Triangle With Exclamation
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.

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) :: C0000 DTC - Red Triangle / ABS / Check Engine And Exclamation
I got my first ever DTC today.... c000 looked it up and it's Toyota Vehicle Speed Information Circuit Malfunction.
It happened as i was slowing down from 70kmh in B mode for a stop light. I felt a small "clunk" and then the beeping and red triangle check engine light VSC ABS and the (!) were all showing. i was at he head of the lights, so when they went green i tried pulling away and had no power. engine was running and revving a little, but there was no drive.
I think the clunk was the HSD releasing maybe? It didn't feel like i hit something, or metal on metal kinda noise. just a dull thud.
Luckily it was downhill and i could pull off the main road onto a side street. I stopped the car, powered down and then turned back on. all warning lights were still on. Then I remembered that the SG2 can read and clear codes ! I checked the code (only 1 was present) this was the c0000 vehicle speed circuit malfunction.
I figured since it wasn't a HV drive code, I could probably reset the code and see if it returned. So I cleared the code and the car returned to normal. i then drove the remaining 5km home with no problems. Seems strange that a vehicle speed sensor malfunction would cause no drive ?
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 (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 (2004-09) :: Master Warning Light / Red Triangle Exclamation Point And Check Engine Light Came On
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 (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 (Gen 2) :: 2007 - Red Triangle And Yellow Exclamation Point In A Circle
I've read some similar posts but I havent found one with the same problem.
View 1 RepliesPrius (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?

My prius has 172k miles on it, yesterday i got the dreaded red triangle and check engine light along with the temp indicator on the navi screen. I pulled over immediately. after sitting for a bit, the lights went away except for check engine. I checked the engine compartment and felt no real heat anywhere. Coolant reservoir was full i drove a few more miles as i was taking a customer to the airport (i work for uber) and they came on again.
After sitting for a few again they went away and i continued on to the airport. on the way back home, about 40 miles or so later, it happened again. again i sat for a few and it went away and i took it to the dealership in my town. they have always been really cool there (an anomaly i know) I never before used dealerships for anything before owning a prius) and he pulled the code for me and it showed POAOF failure to start. that had actually never happened, but was told that it doesn't necessarily mean the car wouldn't start, it can happen while running.
He cleared the code, as i had recently changed the 12v battery and after reading a bit here i know it can cause some weird stuff so i was hopeful that would do the trick. so today i went out and worked again. Drove probably around 50 miles or so and on the way home it happened again. Back to the dealership. This time they put the main tech on it and he also got the code P0121 indicating the throttle position sensor. He took apart the throttle body and tested it and said it was showing not enough ohms or something like that (I know jack all about electrical) and that the throttle body was bad and would need replacing, also saying there was oil in the intake and it would need to be cleaned.
Prius (Gen 2) :: Check Engine Light And Exclamation Sign?
I have a 2009 Prius with about 38k miles. Lately I have been observing that the mpg is constantly dropping and has reached 38 now. For the past couple of weeks, I started noticing a weird noise as if something was rubbing against something else. The noise would come and go, as if something was trying to engage. Upon further experimentation I noticed that it was related to A/C - when the noise would happen, if I raised the temp enough to turn off the A/C the noise would stop. After that if I dropped the temp back, the noise wouldn't come back.
Anyway, today all of a sudden I noticed the A/C was not blowing cold air, so I was sure the A/C went down. However after sometime the car gave me red bang, and it says Problem on the screen with car sign and exclamation, and a check engine light. But the car drives just fine.
Prius (2001-03) :: Check Engine And Red Exclamation Lights On With Codes
My daughter 03 Prius died on her, the codes it threw are listed as P3108, P3191,P3101. We cleaned MAF and throttle and this did not solve the problem. We replaced the MAF with a remanufactured unit from O'Reilly's and now the car drives normally, but the check engine and red exclamation light are still on.

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 RepliesPrius (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) :: 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.
