Prius (Gen 2) :: Check Engine Light And Exclamation Sign?
Jul 19, 2013
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.

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.

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

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.

I just bought a 2006 prius. It had 2 bad cells in the battery pack. I replaced the cells and all seems to be well, they all read the same voltage and the car appears to be driving, charging, working.
I still have the red exclamation mark and check engine light. The only code I get says to replace hybrid battery pack.
There are no other specific codes or issues and it runs perfect. Basically I guess what I am asking is how to clear the light or figure out why the light is still 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."

I have had 3 or 4 warnings in the last two days when trying to start my car.
Sometime the red exclamation comes on and twice the mfd came up with a message about 'P' and parking on a flat surface.
I have a 09 gen2 and I'm on my original battery. Was wondering if its an early sign of 12v battery failure or if its something else?

I am driving smoothly on the highway, doing about 60km/hr, with my A/C working on a full. Suddenly, the check engine and emergency brake light comes up on the HUD along with a beeping sounding. A pull over, and smell a bad odor - like burning rubber - coming out of the hood. I checked and the car was immensely heated and there was smoke rising from a small rubber tube right next to the fuse box under the hood. I turned off the car.
Whenever I would turn the car back on, the smoke would start coming back. I checked several times. I couldn't find out where the smoke was coming from.
When the car cooled down a bit, I checked the radiator. The coolant level was a bit low so I filled up with the water. I also noticed that the radiator fans were not working, even when I turn the A/C on. So I called a towing company and got my car back to my garage.
Now the car heats up after running for a bit and the big exclamation mark sign comes on. The check engine light also comes on. But when the car cools down, the lights go away. I am thinking that the problem has something to do with overheating and the radiator fans not working.

We bought yesterday a 2004 Prius with 73K miles. This was (unfortunately) a private sale. When my husband drove back home with the car, the VCS, ABS and ((!)) yellow came on when he reached 60mph and above. He also noticed a lot of noise when accelerating and the car was shaking. The noise is also there at low speed and when accelerating it is so bad and feels like something is rubbing?
This morning, we decided to try the tire pressure to see if this could be the issue. After correcting tire pressure (it was actually very bad), the lights went off and we decided to try it on the motorway. The car was noisy to start off but as soon as we hit the motorway, the sound was getting worse and worse. I could feel my passenger seat shaking under me and the 3 lights (VCS, ABS and ((!))) came back on and stayed on until we got home.
What was the issue in the end? We have spent all our savings in this car and can't really afford expensive repairs few days after buying it. We are just gutted. Oh and we have a 2011 Auris Hybrid with 15K that runs superb. My dad owns a Prius too and so I can tell the noise is just not normal- at the same time, perhaps a 10 yo Prius is supposed to do this noise?

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.

After coming back from a two week vacation, I tried to start my 2002 sedan toyota prius; and it would not start. The master warning light came on, and then on the screen, the third icon (the farthest right) was blinking in red, it was an outline of a car with an exclamation mark in the middle of it. It does the same thing each time I try to jump it. However, at the same time, after jumping it, the battery seems to be fine, meaning that the display and radio start up fine, but soon after cranking the key, the engine seems to shut off. I bought the car used, so I don't have an owners manual or anything of that sort.

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.

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.

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 ?

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.

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.

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 2004 V10 was loosing power, the check engine sign went on, and it actually stopped running. I got it to the dealer in limp mode. After checking the fault code with VW the dealer said VW told them to replace both turbos and both ECUs . Of course the engine had to be dropped etc.
What are the chances that both turbos fail at the same time? Would not one exchange lets say the ECU first and see if that fixes it? The turbos looked fine when they had them out???? The guys at the dealership were great, making it as smooth as possible, but could not fully explain it to me either....

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.
