Prius (Gen 1) :: Warning Icon And Check Engine Light Popped Up Upon Engine Start-up

Recently there has been a series of problems popping up with the Prius. Its a 2003 model year.

- About four nights ago the warning icon and check engine light (picture below) popped up upon engine start-up and i noticed a weird idle. It seemed to idle rough. After about 20 seconds of idling the engine would shut off. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.

- The afternoon after that the same warning icon and check engine light popped up along with the rough idle. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.

- After this incident it seems like the vehicle is getting bad gas mileage. The picture below shows me getting an average of 25mpg. I was driving very conservatively. Driving the same way i usually do, i usually get 45-50mpg. The vehicle seems to be charging the battery more than usual.

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 (2001-03) :: Hybrid Warning With Check Engine Light On

I have a problem with my 2002 prius. I was driving home from work when all of a sudden my Hybrid Warning light came on with the check engine light on. On the screen, it gives me a (PS, Battery, and ! ) and the "!" was the one lighting up. The engine was roughing up sounds like it was gonna stop itself so I pulled over to the side and it turned off by itself without me doing anything except to put it on park. Then, i took out my keys and tried restarting it and all i heard was the "Ready" beep but not the engine and it won't move when i step on the pedal. After waiting for 10 mins., i tried restarting it and it worked i drove away and got home safely with all the warning lights i mentioned earlier still on. (Note: i was driving w/ the A/C on because it was hot outside..around 90s, also it was not overheating nor it was any battery problem because all the electrical were working properly.)

Prius (2004-09) :: Check Engine Light And Red Triangle Warning Came On?

I have a 2007 prius. I was driving home all a sudden I get a big red triangle warning and the engine logo came on. On the display screen its show a logo of the car at the corner in red with exclamation mark. I use the car obdII scanner but no error code came up. I decide to check the engine oil. When I remove the cap, I notice inside the engine it look weird like a gold color and some blackish. The engine cap inside look like it have stains on it too. The hole where you pour the motor oil down I notice that piece inside don't go down for the funnel to stick in. I attach some pictures. I have no clue what's wrong with it and I don't wanna drive it to make it worse. The prius only have 90k miles on it.

Prius (2004-09) :: Check Engine / Triangle And Hybrid Warning Light Came On

Possible hybrid battery failure in my 2004 Prius (96K miles).

Sunday before last, the check engine light, warning triangle, and hybrid warning light came on when I started my car at the grocery store.

Because I was close to home, I drove home and the car functioned completely normally. The next morning, when I started the car, the same warning lights appeared. However, when I tried starting my car with the headlights off (I always leave them on), no warning lights appeared.

I took my car to an independent mechanic. This is their written report:

"Found multiple check engine codes, P3000, sub code 123, V0100 sub code 211/330. These codes are set when high voltage control detects a malfunction in battery pack/ECU assembly. To check battery pack we took vehicle out on a test drive while monitoring the cells in the battery pack. Found that they are all weak and drop fast when battery is put under a load. Code C2318 is a low voltage error/power supply malfunction code with the auxiliary battery. The voltage spec for setting the code is 9.3 volts, this battery is less than 9.2 volts."

In conversation, the mechanic also told me there was significant voltage variation across the cells in the hybrid battery.

I then took my car to the dealer to try to confirm this analysis. They were unable to read any codes because the independent shop apparently cleared them. The dealer was unable/unwilling to do more than read the codes to diagnose the problem. (Indeed, they seemed surprised that the independent mechanic could monitor the cells in the pack.) All they did was to drive the car around some more to see if the check engine light would come on. It did not.

The car has been driven 80 miles since the warning lights last appeared and appears to be behaving normally. From your perspective, does the report from the independent mechanic make sense and is it believable? And is their test under load definitive of a hybrid battery problem? Could the results be affected by the low auxiliary battery? Also, if I do have a hybrid battery problem, what are the chances of being suddenly thrown into limp mode while driving it?

Prius (2004-09) :: Master Warning, Check Engine, Yellow Brake Light Came On

2006 Prius with 164,000 miles.

First in the morning, starts fine, 500 feet later I'm turning out of neighborhood and I get lit up with:

Red triangle master light

Yellow brake warning (went away after I did signal check)

Check engine

Maint required light

The maintenance light is on because I'm 5,000 miles out of an oil change. I checked the stick, it did appear low, so I added a half quart of mobil 1 5w-30.

The inverter pump was changed due to recall in 2012, and I do still see turbulences in the fluid.

I have 3 pips of gasoline in the tank.

The 12V is a newly replaced yellowtop from elearnaid. Replaced about 1 year ago.

Ford Super Duty (1999-2016) :: Check Air Filter Light Comes On Intermittently With Warning Tone

I have a 2006 Powerstroke F350. Recently, the "check air filter" light has been coming on. It comes on intermittently, and every time it comes on it makes a warning tone. Super annoying.

I reset the minder, and even tried unplugging it. No change. I think I must have a short in the sensor wiring, but I can't seem to find a wiring diagram that shows the air filter sensor.

Looking for a wiring diagram that shows how the minder is wired? Or What is the part number for the relevant wiring harness?

As far as the owner can tell, the car is running fine. He hasn't driven it aside from getting home after the light came on. It seems to give a very informative error message. What it's saying?

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.
