Prius (2001-03) :: Triangle / Check Engine Light Popped On When Driving - Code P3006
I have a 2001 Prius with 210,000 miles. The inverter and traction battery were replaced last year. I started getting triangle and check engine lights about a month ago and the scan tool read p3191 p3006 p0300. The car would barely start in the mornings and the dash lights would be dim. I replaced the 12v aux battery today and all the symptoms went away. Driving home the triangle/check engine light popped on again and I stopped at Orielly's to use their scan tool. It now only reads P3006. I called a local mechanic who suggested to drive it a bit and clear the codes because the battery needed to equalize. Is this true?
View 8 RepliesToyota - Prius :: Check Engine Light Came On - Code PO301 / Misfire On Cylinder 1
I have a 2007 Toyota Prius with just under 30,000 miles. Yes, I don't drive all that much, which makes the Prius the perfect car. I get it serviced every 6 months by the dealer. So far, other than oil changes, the only actual maintenance has been tires, a 12 volt battery, and a $300 "inspection".
A few weeks ago the "Check Engine" light came on. I pulled the code P0301, which translated to "Misfire on cylinder 1". The car was running great at that time, and since clearing the code it has continued to run without the light coming on again. Given that my maintenance is more time-related than mileage-related, it's possible that the ignition system needs attention. However I'm reluctant to bring that up at my next maintenance appointment, because the guy writing up the service order will always answer "Yes" to every "Do I need ..." question.
Passat (B5) :: Check Engine Light Came On - How To Get Diagnostic
Ok, recently my check engine light came on and i read the code with a cheap-o scanner. It read an o2 sensor code (up stream) i then read it again with a scanner that advanced auto parts offers for use, and it read p 1138 i think. I looked the code up on line and it was a fuel lean bank 1 or something like that. All the info i found sugests a smoke test of the vacumm system. I fist did a visual check of the hoses and also a few burst of carb cleaner and listened for the idle to raise but got no results. I also changed the o2 sensor for good measure, is there anything else i can try before i shell out the cash for a full diagnostic.

2001 Camry 4 cylinder. Check engine light came on yesterday. Advance Auto pulled out the code P0446 for the evap. emissions system vent circuit.
The car has no symptoms other than this and is current on all maintenance, but obviously it is a 10-year old car and so it goes.
Toyota - Corolla :: 1998 - Check Engine Light On Then Off After Code P0441
About two weeks ago, while driving on a hot, humid summer night, the check engine light in my 1998 Toyota Corolla came on. The following day, I took it into my mechanic, who plugged it in and came up with the code P0441 (Purge flow fault). He told me it was likely related to the fuel vapor canister, though I see this can also have to do with vacuum lines for the purge valve and canister or a bad purge valve itself. My gas cap was, and had been, tight, so it wasn't something as simple as that.
Reluctant to deal with this immediately, I went back to driving it, and lo and behold - the light went off after several days! Unfortunately, the light came BACK ON after several more. And most recently (a few days after coming on again), the light has now gone off!
Both times the light has gone off, the weather has been rather wet, but otherwise, there doesn't seem to be a clear pattern. What this on again off again pattern might say about the problem?
Toyota - Solara :: 2000 - Check Engine Light Code P1410
I have a 2000 Toyota solara. Everything runs fine. No misfires or weir sounds. But the check engine light has been turning on and off. It turns off at random times and usually turns back on after I get gas. I finally got the code scanned. It is P1410. While at autozone I got a new gas cap based on prior postings and filled up the tank to see if that trick would work. To my delight, the cel turned off upon starting the engine. It remained off for thirty minutes before it came back on. So now I am stuck with the code.

I have recently had about $1620 worth of work done on my 2000 4Runner because the check engine light came on and the code was P0420.. My invoice says they replaced the exhaust pipe assembly. Now 2 weeks later the light is back on with the same code...are the 02 sensors part of the "exhaust pipe assembly" or are they now going to tell me I need a bunch (2-4) 02 sensors replaced.

View 7 RepliesToyota - Camry :: 2001 - Check Engine Light On / P0440 Code
Check engine light was on for some time when I had filler neck and cap replaced. Computer sensors did not re-set until 501 mile mark, when light came on again. Checking the web, I find that some who appear to have knowledge of problem say it could be hoses, sensors, valves, or evap canister--the charcoal canister.
Mechanic who did original smoke test and recommended replacement of filler tube wants to replace evap canister without checking anything else. What should I do? At wits end, and car needed to pass inspection 2 days ago. Car has 157,000 miles or so...

View 1 RepliesToyota - Matrix :: 2007 - Recurring Check Engine Light / Code Was P0741
I bought a 2007 Toyota Matrix new, and it now has 41,800-something miles on it. At 38K miles the check engine light came on while I was on vacation out of state. The nearest Toyota dealer checked it out, told me the check engine light code was P0741 - problem with the torque converter - but they didn't see any obvious problem and the car drove fine for them and for me. They turned the light off but it went back on before very long. The car has now been to 2 different Toyota dealerships near my home because the check engine light keeps turning on. They also report seeing the same code, also seeing nothing obviously amiss,and tell me I need my transmission replaced. This seems preposterous to me for such a low mileage Toyota.
In December, when the check engine light went on again, I discovered it would turn off if I filled the car with gas. It still comes back on; if I either fill the car with gas, or simply open and close the gas cap, the check engine light will turn off after 3 - 4 trips with the car. What does the gas cap have to do with the torque converter?
What's really weird is that the light always comes on under the same conditions. Most of my driving is short trips, a couple of miles in town at around 30 mph. The light never comes on during "town" driving. My highway driving consists of trips of about 1 hour; parking for an hour or two; then returning home -- again, about an hour's drive. The check engine light always comes on when I'm doing highway driving on the trip home. I've clocked the mileage for the last 3 times the light came on. It came on after highway driving a total of 48, 51, and 48 miles, respectively.
Toyota - Camry :: Check Engine Light Code - Catalyst System Efficiency Below Threshold
My 1999 Camry with 169700 miles has this 'check engine light' code: "Catalyst system efficiency below threshold". We have a mechanic we trust so we'll bring it to him this week. We spent a couple thousand fixing this car about two years ago and I'm not sure it is worth doing that again. Carmax offered us 1200 for it around this time 2012.
View 17 RepliesPrius (Gen 1) :: Codes P3006, C1213, C1259 With Warning Lights Diagnosed
Here is my situation- back in 2014 I had a local mechanic replace my HV battery and 12V battery after the Red Triangle of Death. Well yesterday that triangle reared its ugly head again! (and cruise control stopped working) Since this mechanic has 3 year, 36,000 mile warranty on all parts and labor, I figured this should be covered. I drove my wife's car to work today, then after work drove the Prius over there to find them closed until Friday!
So I had the guys at Advanced Auto read the codes for me and got P3006, C1213, and C1259. I have done extensive reading and researching, much of it on this site on these codes, but my main question is this:
I commute about 20 miles one way, and on certain days my wife commutes 10 to 22 miles the opposite direction. There are 3 days we go opposite ways this week, and at least one that is completely unmanageable without 2 cars.
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.)

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?
