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) :: Red Triangle, Exclamation, VSC And Check Engine Lights Came 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.

Prius (2004-09) :: Triangle Warning And Check Engine Lights Went On

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?

Prius (2004-09) :: 2008 - Red Triangle / Check Engine And VSC Lights On - Low Acceleration

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.

Prius (2004-09) :: 2005 - Triangle Warning / Check Engine And Brake Lights Came On

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.

Prius (2004-09) :: Red Triangle With Exclamation Point When Turned Right At 20 Mph

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.

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 (2004-09) :: Brake / Triangle / ABS And VSC Lights Came On

Recently while pulling into the gas station the brake, Triangle !, ABS and VSC lights came on. The dealer reset the error and said my ECU needs replacement at a cost of $1843. The Prius is a 2005 with 147000 miles. No problems since the reset so I am hopefull. I don't recall reading about a lot of others having to have expensive ECU replacements so I wonder how many have had similar problems and replaced their ECU.

Prius (2004-09) :: Red Triangle / VSC And ABS Lights Keep Coming On

The battery in the back looks like it got smashed a little. Do you think this is the cause of the lights? It was a small suv so it missed the bumper and went straight into the battery area. Trunk wont latch anymore the it got pushed in.

Is there an electronic box back there that could have caused the lights to come on?

Prius (2004-09) :: Brake - Triangle - ABS - VCS Lights Came On?

Just bought 04 prius. Anyhow fast forward to yesterday and I am driving home and notice the Brake light, (!), ABS, VCS lights come on. I read a couple forums about bridging pins 4,13 to get codes and this is what I have. (!)69, 57 ABS 42, VSC 45

I tested the battery and it was 13.8 V on and around 12.3 or something off. I felt around where the inverter pump is and it feels like there something going on in the middle hose. I tried to look in the reservoir but honestly I couldn't get it pumping when I had the hood up so I couldn't confirm movement in the reservoir.

I reset the codes (stomping on brakes 8 times) and it went away until I started driving home again today and they;re back. I added a file the is the sounds I hear when pressing the brakes. Truthfully I hear this all the time when I turn off the prius. I just noticed though that when I hit the brakes I hear it now. In the sound file you hear a pause when I press and release the brake pedals and reapply.

Prius (2004-09) :: Red Triangle Along With Bunch Of Other Lights On Dashboard

I have had the Prius for a little over 2 years now. Bought used and currently close to 150K miles on it and have put on about 25K miles a year.

This evening on way back home, when I turned on the Prius, I got the Red Triangle along with a bunch of other lights ON the dashboard.

Pressing the power button and everything would take much longer than usual - the lights(on the clock) was dim, the windows moved up and down rather slowly.

Eventually, i had to jump start and carefully drive home. Afraid it would stop somewhere at stop signs or long red lights, i constantly kept pumping the accelerator(not sure if that was good). Seems like need to replace the 12V battery.

Prius (2004-09) :: All Dash Lights With Red Triangle Came On While Driving

2007 Prius 215,000 miles. Car has been a champ for the almost 2 years I've owned it, buying it with 150K miles. No real troubles and I've been driving it constantly as you can tell. Had an extended warranty repair done back in the winter when dash lights went out completely yet car would still start & run. Replaced 12V battery back them trying to diagnose trouble and it was original battery anyway. Daughter was driving when almost all dash lights came on including the red triangle. She came back home, turned it off. Next start was just red triangle and check engine light with red car on center display. Now it's just the check engine light and red car after sitting for an hour. I plan to take it in to get check engine light checked out.

Prius (2004-09) :: ABS, VSC, Triangle And Parking Brake Lights On

I replaced my rear brake shoes this past weekend. Immediately after I replaced them, the ABS, VSC, ((!)), and Parking Brake lights came on. I had not read that I should've disconnected the 12V battery before changing the shoes, so I wonder if that's related to the issue. I've read through as many threads here that I could dig up, but I still have questions. Here is what I know so far:

Car Info: 2004, 210k miles, Original 12V battery

Relevant Info: While replacing the shoes, one of the seals(?) (rubber part that slid over the piston(?)) slid off. I put it back on, and have checked for any fluids leaking, and have found none. I may pull the rotors off and check this again, though. There were no DTCs logged prior to the shoe replacement. Battery has shown no signs of dying, although I am going to check the voltage on it after I post this.

I tried jumping the pins, and I get the following flash codes (I tried resetting, but they came back immediately):

ABS: 4-2
VSC: 4-5
((!)): 6-5

I tried finding information on these flash codes, but have found nothing...

My CHS Tank was damaged in an accident a few years ago. I just replaced the CHS tank and the Inverter Coolant Pump within the last 12 months. It is still running when I power the car on and off as it should. I also jumped the fuse with a paperclip to double check that it runs.
My brake fluid levels are fine right now.

Possibly unrelated to the lights, but applying the parking brake is very easy. I don't think I adjusted the star adjuster enough. This is my first time messing with drum brakes, so it's possible I didn't adjust that correctly. Are these self-adjusting, or do I need to go back and adjust them by hand?

Prius (2004-09) :: Brake - Triangle - ABS - VSC Lights On Dashboard?

I have done some maintenance on a recently purchased 2004 Prius. Namely, replaced the inverter cooling pump, the right front wheel bearing and rear brake pads.

At a certain point, the brake, (!), VSC and ABS lights came on on the dashboard.

My wife is driving this car so I did not get the exact moment when the lights came on after my repair jobs.

I then replaced the 12V battery with a new one and reset the lights with the PIN 4-13 jumper on the OBDII connector. I did retrieved the error codes of each light and I googled them without any result and I now lost the paper where I had then written on

Prius (Gen 2) :: Red Triangle, Brake And Check Engine Lights Popped Up

Yesterday on my morning commute, the red triangle, brake light and check engine light popped up on my dashboard. After about 10 more minutes of driving I lost a lot of my driving power. The system screen showed that there was no brake regenerating happening. I could hear the battery fan going behind me pretty loud.

Prius (Gen 2) :: 2005 - Triangle And Engine Icons Warning Lights Came On

Bought a new Prius in 2005. In April 2010 (157,000km / 98000m) the triangle and engine icons warning lights came on. After about two weeks in the workshop, I was informed that the main battery went. Two months later (161,000km) the same warning lights came on again. Toyota agents informed me that now it is the water pump not circulating water through the engine. Toyota on its website states that the batteries should last the entire life of the vehicle. Is it possible that battery problem was wrongly diagnosed, and, that in fact, it was the water pump giving the problem in the first place?

Prius (2004-09) :: Check Engine Light Turned On For A Few Hours Then Turned Off

I always take care of my car oil changes on time. And in the last week my check engine light turned on for a few hours then turned off. And today it turned on again. I kinda regret getting rid of my scan gauge now.
