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 RepliesMy 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
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.
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'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.
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.
View 17 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 RepliesYesterday, 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.
I have 2011 prius 1800cc.
My car dashboard display come ORANGE TRIANGLE WITH EXCLAMATION MARK light and message "HYBRID SYSTEM CHECK". Car has no problem in drive, every thing works but display computer (check consumption graph Charging wheel etc.) does not show.
When I press start, display button shows charging graph consumption etc, only for few seconds and go to msg check hybrid system.
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.
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'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 Prius is an '04 with 156k and it will only start with a jump box. I went into the display and found the 12 volt battery reading 12.2 volts after sitting for 4 hours. When driving stop and go around town I will get the red triangle of death and vsc lights but NO check engine light comes on. Using a Scangauge it shows no codes, system ready. I look into pending codes and there is nothing. However when I force clear pending codes the triangle goes away.
It's strange there are no codes associated with this fault. I'm thinking to drive it and not force clear the pending codes and maybe a code will show up eventually but I'm not sure.
I had just started driving this morning, when I a beeping sound came on and the Brake light, red triangle, and the check engine light came on at once, it is a 2006 Toyota Prius and it is my first car so I am still new to diagnosing the issue with my car.
View 8 RepliesI have a 2001 toyota that I was driving yesterday. I parked my car on the side of the road for 2 minutes to find something in the car. Randomly after a minute of being parked the car suddenly flashed the red triangle on the dashboard as well as the check engine light.
Also as well on the main computer screen where the radio stations normally are displayed a Problem alert appeared. It shows the PS icon, the Battery Icon, and the Red Car exclamation icon. Only the Car Exclamation point is red.
As some basic steps I tried (Because I don't know that much about cars) I opened the hood when the engine was off and cold and checked the air vent filter to see if it was clean. I cleaned just in case. I also check the gas cap to see that the cap was closed tightly. Also checked the tires air to see if that could be the case. Oil was looked at by me and I didn't see anything abnormal as well.
I have a 1st gen prius. Got the triangle and check engine light which is p3006... I checked the battery all cells are above 7.5. I notice the inverter coolant is low which I'm adding some today. Even tho it was low is it supposed to be moving or is my pump out? i did not see the waves or bubbles at all.
View 2 Replies2006, 2G, 43000K. This has happened twice now. Both times on an extended trip of 3+ hours in hot weather: Cruising along at about 70 MPH, the engine just quits. RED Triangle; check engine light; and vcs light. Turned everything off. Car would not restart right away, but after waiting 15 minutes or so, the car restarts and runs fine. All warning lights off except check engine light.
Immediately drove to a Toyota dealership where the following codes were found: P0AOF info 204 (Engine failed to start); and P3190 (poor engine power). The Tech checked the EFI relay; checked for oil puddled in intake; and checked for a contaminated MAF sensor. "No problems found"!
I got my oil changed today and thought everything (10 am) was fine with my car. I drove it straight home after the oil change. About 4pm I drove it to work and no problems still. Finally tonight on my way home right as I turned on to my street the car at first seem to hesitate. Slow a bit and I pushed the accelerator. Then suddenly as I pulled in my drive way the engine began to shake as though I was about to stall and the check Engine light came on as well as the big red triangle.
This has happened before. The display being lit up like a christmas tree so but this time the engine shook. I turned the car off, check the oil, which is full and the coolant which is full. The engine has not shook yet ( but I wont leave the car on for a long time to see if it happens again) the Red Triangle has turned off and now only the check engine light remains.
I am going to call Firestone, that is where I got the oil change all I know is that they did a routine check up (unauthorized by me) and told me I needed a new water pump drive belt and tires and a air filter..... So I am hoping they didn't touch something by mistake. I told the man that I would much rather have that done by the dealership.
