Prius (2004-09) :: Engine Is Revving At Times And Not Shutting Off When At Stop Light
May 21, 2012
Our 2005 Prius with 160,000 miles is displaying warning lights and the gasoline engine is reving at times and not shutting off when the car is at a stop light.
The dealer says it is throwing a P3000 and P0A80 codes. I asked for subcodes, the dealer doesn't know what I am talking about.
The dealer wants to replace the hybrid computer for $900 and if that doesn't fix it they want to replace the hybrid battery for $3500.

So it's an issue I've noticed 3 times now this summer. The car has been driven for at least 5 minutes each time and should be past the warm up phase. If I'm sitting at a light, the gas engine just keeps running. I thought it might be some kind of computer error so I tried powering the car off and turned it back on. EV mode will stay on for about 30 seconds but then the gas engine turns on again. Battery is 3/4 full like normal with the AC on. I've tried putting the car in EV mode but it says "not available". Temps in Houston have been in the high 90's recently so I'm wondering if this is the result of an overheated battery or if it's something I need to be worried about and take in to the dealership?

So coming home from work the engine started misfiring and the Service engine light started blinking five times in staying on for five seconds and then blinking another five times in series. The car started writing very rough and stalled out every time I came to a stop which was not normal function for vehicle. Made it to the Toyota dealership. After paing the Service fee they told me it was possibly spark plugs, ignition coil pack, and an O2 sensor not functioning. I just changed the spark plugs and ignition packs three months ago. So I took the car home put new spark plugs in and a new ignition pack I ordered from Amazon and put it in cylinder for (which they told me at the Toyota dealership) and installed a new O2 sensor myself. Disconnected the battery to clear any trouble codes and restarted the engine. The problem still exists. The trouble code they gave me at the dealership was.p0304, p0138, p0110. The car is still miss firing and Service light keeps blinking.

Very hard to describe this sound but it is coming from under the hood and lasts for about 10 seconds.

Three times recently my 2008 Touring Edition Prius has experienced a shutdown of the engine while driving. Each time I was able to coast and/or use battery power to get to a safe location. The “Triangle-of-Death” and the Check Engine Light was illuminated on the dashboard. Since my car is equipped with a scangauge, I was able to see the codes and clear them on the spot. After restarting the car, it showed no adverse reaction to shutting down and all was seemingly well until the next event. The codes listed below all seem to be communication lapses.
My question is; where do I start in my pursuit to diagnose and repair?
7/15/14 - 98,889 miles U0293 and U0100
7/23/14 - 99,414 miles U0293 and U0100
8/21/14 - 101,065 miles U0100 and U0000

I am afraid to drive my car on the highway and if I am damaging my car by driving it I want to make sure I hold the auto care shop that put the wrong size tire on my car responsible.
I have Bridgestone Ecopia EP100 BL tires size 185/65R15 on my 2007 Prius that I got in 2010. Because of a nail in one tire I had to replace one of the tires two days ago. The technician said they did not have the exact same tire any more but he would replace it with something comparable.
The next day I drove 2 hours on the interstate and the slip indicator light kept flashing, it felt like the engine was revving a lot and/or the transmission wouldn't shift when I got to highway speeds, and it was a little scary. My first thought was something with the new tire since I had absolutely no problems before.

The electric radiator fan motor in my 1992 Buick is begining to squeak. It's most noticeable during its gradual stop after shutting off the engine. Will WD40 or some other lubricant applied to its shaft remedy the problem? Or, will it be just a temporary fix before its inevitable failure?

I've had this happen twice: I'm stopped at a light (on relatively level ground--only slight incline). My gas engine kicks off. OK, fine. As it should. But then it comes on again, maybe a second or two or maybe three or four later, while I'm still stopped. First time, it did this a few times back and forth, all while stopped, waiting for the light.

I'm still trying to get a manual for my recently acquired 2004 Prius, so I can't trace down what this means....
When I start the car, recently, a "Maint Required" light comes on and flashes about three or four times, then goes away. This is after all the other dash lights during the test phase go out. When I took it to have the codes read, the device said "No Codes" stored.
What does this mean? And is it a serious problem?

I just bought a 2004 Kia sedona ex, it was running great when I got it, and it has 81000 miles. On the way home it kind of sputtered a couple of times, then the engine light came on. I took it to autozone and they said 2, 4, and 6 was misfiring. I called the dealer and they said that it was probably because I didn't click the gas cap three times. Could that be the cause or do I need to change the spark plugs or coil or something??

2005 Prius...113k miles...master warning light & a coolant temperature briefly light up several times while commuting. The inverter coolant tank stays full, but the motor coolant is empty every day after a 30 mile commute. I fill it up & 30 miles later it is empty. There are no puddles or evidence of a leak while parked in the garage.

Purchased used 2006 and the left tail light does not work at times until I rotate the socket as if removing it. This happens frequently and then after about 3 weeks the bulb blows. I've confirmed the there is no socket terminal issue and no intermittent opens in the wiring to the socket. The buld internal glass blackens as if it is running too hot but the voltage measures slightly over 12V when I've measured it. The bulbs are rated at 13V. At this point the only thing I can think of is there must be an occasional high voltage spike that hits the left tail light but not the right tail light.

for the last three days, I had the big red master warning light come up four times during normal braking, also "Problem" was displayed on the LCD where "Add fuel" is displayed when fuel is low. But no error code showed on the OBD reader. I searched found that it might be related to 12V battery which I replaced two years ago.
2008 with 120K miles.

My "Maintenance Required" light on the dash is flashing 4-5-6 times when I start up the Prius every time, why?...
I went through all of my Maintenance menu items and most of them arent set to begin with, but the ones that ARE set, still have 4000+ miles til the next service...

On my V6 2004 (just hit 120,000 kms, just changed the oils 2 weeks ago) I was driving on the hiway yesterday, when the whole vehicle started shaking and vibrating - engine light blinked a few times, then stayed ON solid.
I could reduce the shaking by letting go on the throttle pedal, so I stopped and checked, nothing obvious, oil level good etc. I could hear some sort of clunking noise when engine was revved up.

I most recently drove my 2006 Prius around on Saturday Feb. 1, with no problems at all. I went out of town for a couple of days, and returned this afternoon to a car that will not start. I stepped on the brake, pushed Power, and things lit up, the "Ready" light flashed a few times but then went off. Power button light stayed orange.
Several warning lights on dash stayed on (!)/ABS/VSC/traction control, and a message came on the screen saying something about a problem with "P" parking, and that it should be parked level and the parking brake applied. It is sitting level with the parking brake applied already. Also, the door ajar warning light and beep start as soon as you open the car door to get in.
I'm thinking from what I've read that my 12v battery has died/is dying. I'm the original owner, bought car in March 2006, and it has just under 61,000 miles on it.

I have a 99 acura TL. The car generally runs well, but at times, and without warning the engine will stop. I can be driving at 70 and it will stop. Usually it starts back up again right away.
Sometimes it will be a little harder to restart, requiring up to ten times to restart. The it runs perfectly.I have replaced a number of sensors as well as the EGR valve. I just can't seem to figure this out.
As of right now check engine comes on. Prior to that other codes have come on. When it stalls, it just stops cold. There is no warning and no indication it is going to stall.

I have 05 Caravan, 4 cyl, 115k. Runs fine (just got back from a 2000 mile trip) that seems to have a quirk or something with the AC.
When I have the AC on and stop at a light, it feels like it hesitates several times. I almost think it'll stall (never has). I usually end up turning off the AC while we're at the light, and start it back up when I accelerate. When the AC is off, there is no hesitation. Also, If I put it in park, and we have the AC on, no problem. I rarely, if ever, have the recirculation going.
One thing of note: I usually wait until I'm out of our neighborhood and on the main street before turning it on. That means the windows are down until I turn it on. When I do, occasionally I hear a sound that best can be described as similar to the sound of loosening a tight lug nut. Still, as long as I'm driving, there is no hesitation and it cools fine.

Basically i have an integra here used to be a gsr with a type R engine. Basic bolt on's and 8lbs flywheel, 6 puck racing clutch. Here are the problems, i hate fixing other shops messes but here we go. When sitting at a stop light if we hit the brakes a few times every time we do it the rpm's drop and start going up and down, some times when the car is just sitting there idleing it does it. Had the same problem on a del sol with a gsr engine and b16a2 head on it done from the same shop. Also when its cold the owner complains that it will take him like 1/2 hour to start it. I was thinking that the grounding wasn't good enough. The check engine light is on as well, but how to get the ecu codes out of this ecu.
