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.

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 (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.
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.

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 (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) :: Check Engine Light / Orange Triangle And Car With Exclamation Point Lit Up
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) :: Triangle / VSC And Yellow Exclamation Lights On With No CEL - Code P0A09
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.

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?

Some days ago while I was driving, the check engine, red triangle and vsc lights came on and immediately my car slowed down. It would take longer to accelerate and every once in a while upon getting to a stop sign, it would take long to get to 5 from 0. could this be my hybrid battery going out? My regular scanner can't pull up any codes on a prius.

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.
Prius (2004-09) :: Red Triangle / Check Engine Lights Appeared When Driving On Freeway
I was on my way to work this morning when the car just stopped accelerating (or so it felt), all the dash lights came on, I pulled over to the side of the freeway (I was very lucky). Radio and a/c were still working. Powered off, powered on too soon a couple of times - the red triangle and check engine both came on again. Cooled my jets and gave it a few minutes, powered on and the red triangle was gone, but the check engine was still on. Drives perfectly, no problems w/either gas or hybrid engine.

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.

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.
View 17 RepliesPrius (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.
