I just had my hybrid battery replaced this weekend for the 2nd time in my 06. Drove it home, was about a hour drive and everything is going good. Well go to drove it this morning and check engine light is on. It has anything to do with hybrid battery chance?
View 15 RepliesI just switched out my hybrid battery and put in a brand new one. Now, the car isn't doing anything and all that's on is the check engine light. What now? I was told I had to tow it to Toyota and have them reset the computer. Sound right?
View 7 RepliesSo this morning when i started up my car the cel came on. The car seems to be running fine so i decided id try to go to work and hope for the best. Well nothing happened and i made it to work fine, but i noticed i was always regenerating power. My drive is 45 miles all freeway and little traffic most the drive.. ive never had this happen on my drive to work and ive had the car for a year now. Could the hybrid battery be dying? i have a cheap scan tool but that doesnt mean i will get the correct reading...
View 16 RepliesMy check engine light came on, I took the car to my usual mechanic, and he said the codes returned indicated that two cells in the batter were bad. (I just called to get the codes, but he's out of the office for about 30 minutes on a test drive...)
View 8 RepliesI have 2005 Prius with 300k miles. I started throwing P0A80 code. I removed the battery and checked all the modules and found 2 of low voltage, ordered them from Ebay and replaced them. I placed the battery back in the car and started the car but got P0A80 code again. I purchased the grid charger from Hybrid Automotive and connected it according to their instructions for 24 hours. I drove a car but got the red triangle again and P0A80 code again. I removed the battery again and tested the voltage of all the modules and these are the readings:
View 4 RepliesI own a 2005 prius. It is stock and i recently had the check engine light pop up as well as "problem" when car was started and 2 lights with exclamation point, one on a car and ones in lil brackets. I believe it is called a "hybrid malfunction light". Well one day they all pop up and about 3 days later theyre gone. Only thing i did was fill up the tank, when they came on only 1 bar was left on the tank. My question is should i still take it in to see whats wrong with it? and what could of caused both lights to come on?
View 1 RepliesPossible 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?
I went out in the 9 degree temp this morning to start my car and take off for work. I sat down and hit the power button and some console lights came on. The gear lights were blinking with a square light around each letter (P, D, R, B...) and the pips on the fuel gauge were blinking, beeping during each blink. Also, the green light on the power button was blinking and the little light showing that the key was not in the car was also on but the key was beside me. I turned it off to try it again.
Before I turned it back on, I inserted the key in the slot and hit the power button again and just the Check Engine light came on and everything else was black. There was a slow tempo click-click-click-click... sound coming from under the hood and the Check Engine light was just sitting there. I tried to turn the car off but the power button was not doing anything. All I could do is let the Check Engine light stay on and the click-click-click-click... sound chirp away. I went back out in a couple hours and the battery was dead.
Just seeing if that might mean something specific before I go drop about $200 on a new 12v battery later today.
My husband just replaced the spark plugs in my 2005 prius with 174,000 miles (also replaced the right headlamp bulb). When I started the car, the PROBLEM check engine light Hybrid Warning Light came on.
Owner's manual says take it to the Toyota dealer. The dealer is 50 miles away. Is it safe to drive it the 50 miles? It drove okay up and down my driveway.
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.
A little less than a month ago the "check engine light" came on and I panicked. Lit up orange, not red and it was flashing, just a stagnant orange check engine light. I tried do some research and found that the gas cap was the majority reason why it tends to go on.
I checked my gas cap, and I thought it seemed lose by what it seemed like a simple screw off. So I screwed it back on and made sure I heard the couple clicks. After about 2-3 runs and turning the car on and off the light disappeared.
The next day, was driving and it came back on. I didn't even mess with the gas cap. Over the next period of days, it turned off, then turned on again.
I have a check engine light that doesn't know what it wants to do.
Our 2005 prius has logged 170,000 miles (we purchased it used with 90,000) and this is the first time we've ever ran into any issues with it, love the car. Well, a few weeks ago the check engine light came on and we just happened to have an emissions inspection that week, which was failed because the check engine light was on (they didn't even test the exhaust).
After taking it to a local dealer to see what the check engine light was all about, they came back and told us it was related to the Coolant Heat Storage system and that the CHS temperature sensor would need to be replaced. They also told us that the water pump had a minor leak and would need to be replaced. Another non-related but related issue is that the driver side wheel liner was ripped out when my wife decided some off-roading... and after seeing where the CHS is located this might be a factor.
Could low coolant levels (related to the water pump leak) be causing the CHS temp sensor alarm? I'm making an appointment with the dealer to have water pump replaced (or may DIY if the job isn't too bad), I'm just wondering if I should hold off on the CHS related parts until that has been fixed. I checked all the connections and everything seems good, no corrosion yet. The temp sensor is on the front side of the tank so it wouldnt be getting splashed too much by the wheel even without the liner.
Quick question, my wife wasn't able to open our '04 Prius with the FOB. I replaced the battery, and the FOB started flashing, which I'm assuming means that the new battery is working properly. However, after I put the FOB back together, the lock/unlock buttons still don't work. I can still manually open the car with the attached key and start the car with the FOB, but I was wondering if there's still a problem.

I just replaced the 12V battery with an Optimus yellow top. The car still will not start. All dash lights come on, READY light does not. Car will only shift into Park and Neutral.
Battery reads 12.6 volts when not hooked up and 12.3 when cables attached to terminals.
2006 Toyota Prius, bought new in Oct 2006, currently at 90,000 miles.
It just recently broke down on me about a month ago, the dashboard lit up like a Christmas tree with every possible light flashing and nav screen showing "problem." I took it to the Toyota dealership and they determined it was a hybrid system fail and replaced the battery.
After this, I'm thinking all is well. I go out of town this past weekend 130 miles away from where I live and day 2 into vacation my dashboard lights up again! Same lights, flashing red triangle, Vsc, check engine, etc. it gets me back to my hotel but the next morning the engine won't start. At least the first time it broke down the cars engine worked and was somewhat drivable.
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.)
View 11 RepliesThis car has been giving me quite a bit of trouble lately. 04 Ford Taurus SES, about 97,000 miles on it. Just last weekend, it broke down on the highway. Found out the torque converter failed and needed to be replaced. I was suspecting that something was wrong with the transmission for a while now, because it would stutter sometimes when accelerating, and sometimes start shaking in the front when I turned it on. (It still stutters after having the torque converter replaced.)
Well now, a day after shelling out quite a bit of money to the dealer for this torque converter, the check engine light is on. I went to Autozone to check the codes, and they found P0300, P0305 (cylinder misfire) and P0316 ("crank sensor condition"). Is it possible the transmission is failing?? I found a bunch of complaints online about the transmission failing on the 04 Taurus. I'm trying to avoid more expensive repairs, but I don't want the car to break down on me again....
Also, a couple months ago, the check engine light went on a few times, but always went off within a day or two. Never did get it checked out because it didn't stay on long enough.
I own a 2004 Ford Escape, auto, v6. I bought the car in 2007 and have had trouble with my check engine light ever since. It is usually on, but will turn off shortly after I wash it (then back on a week or so later). When mechanics test for the code, they say that my catalytic convertor needs to be replaced. In addition to the on/off strange behavior, I have been driving this car for 4 years now with no major mechanical trouble that I can only assume would result from not replacing the CC. This would be very expensive repair, one I am not interested in doing if this is possibly just an electrical problem. I am ready to get this problem solved and start driving check engine light free.
View 3 RepliesI have a 2010 Prius, currently at around 69,000 miles. Back in Feb 2015 (when it was just under 60,000) I was driving on a city street and hit the accelerator once a stoplight turned green - immediately as I took off (at a normal rate of acceleration) my 2010 Prius made a loud noise and I got the red triangle of death, with a "Check Hybrid System" message. The car quickly shifted into "limp home" mode and I was able to make it back home as I was only about a mile away.
Got towed to the nearest dealer the next morning and after tons of testing and going back and forth, they replaced the transmission and inverter (was able to get it covered under powertrain warranty), and I was on my merry way. No issues until last night.
Yesterday evening, I am on a city street and get a warning beep. I look at my dashboard and this time I have a yellow exclamation mark with the "Check Hybrid System" message yet AGAIN. Towed the car to the nearest dealer and am now waiting on next steps. Only update I've gotten so far is that they are still trying to diagnose the issue, and are getting 4 error codes in this process, 2 of which are new. I am waiting on the technician to tell me what the actual codes are - hopefully should get them tomorrow.
I would hope if it's another issue with transmission or inverter, it's covered under warranty given I replaced both less than a year ago. However I'm not sure and am worried that it's going to be $$$ in case it's something else that failed. Plus I'm getting serious doubts as to the safety of my car - what if I had been moving at a high speed on the highway during either of these situations?
The engine check light is ON this morning. It said that there are problems for the hybrid system on the display. I sent it to dealer immediately.
View 7 RepliesTested and replaced 2 bad battery cells in my 2007 Prius... Got everything put back together and now all dash lights are on and engine won't start... When i try to shift into drive or reverse it goes directly into park... I tested the battery without removing the safety key and the inside terminals are at 220 volts and the outside terminals are at 0 volts as shown by photo... Maybe due to a fuse somewhere?
