Last year my check engine light came on a couple of times at the end of the summer but it went away and I can't remember how. Today was the warmest day of the year so far for us and my check engine light came on again. It seems to happens when it's warm, I'm accelerating and I think the A/C is on but I can't be 100% sure about that.
View 19 RepliesI've read the pages on engine oil level and changes in the awesome 2004-2009 manual by John's Stuff - Toyota Prius and more.
Great information on overfilling of engine oil. Among others I read:
"The ideal level is 1/4” (one-quarter inch or 6 millimeters) below the "full" mark, which is between the D and the E on the photo above." (p.27)
This morning I tried to drive my 2008 Prius and the "check engine" light quickly blinked and the dashboard didn't light up. The monitor did turn on and I could hear the engine running. The monitor showed that the hybrid battery was almost full. While trying to go in reverse, the camera did not work. We just had an oil change done. The 12V battery was replaced almost 2 years ago. The car has almost 150K on it. I also tried tightening the gas cap. It's obviously winter and it snowed last night (in case that might be a factor).
View 19 RepliesI have a 2007 Prius which today, for the first time ever, refused to start. I pressed the Start button and all that happened is the "check engine" and "airbag" lights came on (dimly), and the green LED on the "P" (park) button began blinking. I pressed the "Start" button again but nothing I can do will change this. The car is sitting in my garage now, in this condition. I turned the dome light on briefly and it was very dim, so I suspect the 12v battery is dead. Only problem is, to access it requires opening the back hatchback door, which won't open without 12v power. Meanwhile the tiny bit of power that's left is being drained by the system in it's half-on condition (above). If I could get to the battery I could connect an external charger to charge it up enough to start it but I can't. What should do?
View 19 RepliesI was wondering if this seems reasonable. I just bought a used 2008 Prius top trim package with 107,00 miles on it this last month. The first day I owned it a check engine light was triggered. The guy I bought it from hooked it up to his computer and cleared it to then try to trigger it again. This happened when I first turned on the car. I started backing and then it turned on. I didn't know what caused it as we couldn't trigger the response again. It's been a few weeks now and 1 trip to the shop for some repairs. There have been no problems what-so-ever since then and my Prius just started getting close to the 50 MPH as advertised after a tune up.
Today when I'm driving, as the seller did mention before could happen, the right headlight turned off. As he had told me before, just turning the lights off and turning them back on will get it working again. I did this and as soon as I did the check engine light came on. I go back to the night I originally had it happen and I was probably in the process of turning on my lights.
2006, 2G, 43000K. This has happened twice now. Both times on an extended trip of 3+ hours in hot weather: Cruising along at about 70 MPH, the engine just quits. RED Triangle; check engine light; and vcs light. Turned everything off. Car would not restart right away, but after waiting 15 minutes or so, the car restarts and runs fine. All warning lights off except check engine light.
Immediately drove to a Toyota dealership where the following codes were found: P0AOF info 204 (Engine failed to start); and P3190 (poor engine power). The Tech checked the EFI relay; checked for oil puddled in intake; and checked for a contaminated MAF sensor. "No problems found"!
I got my oil changed today and thought everything (10 am) was fine with my car. I drove it straight home after the oil change. About 4pm I drove it to work and no problems still. Finally tonight on my way home right as I turned on to my street the car at first seem to hesitate. Slow a bit and I pushed the accelerator. Then suddenly as I pulled in my drive way the engine began to shake as though I was about to stall and the check Engine light came on as well as the big red triangle.
This has happened before. The display being lit up like a christmas tree so but this time the engine shook. I turned the car off, check the oil, which is full and the coolant which is full. The engine has not shook yet ( but I wont leave the car on for a long time to see if it happens again) the Red Triangle has turned off and now only the check engine light remains.
I am going to call Firestone, that is where I got the oil change all I know is that they did a routine check up (unauthorized by me) and told me I needed a new water pump drive belt and tires and a air filter..... So I am hoping they didn't touch something by mistake. I told the man that I would much rather have that done by the dealership.
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.
My 2004 Prius currently with 212,200 miles has the check engine light on. Brought it to Advanced Auto Parts where they will diagnose for it for free and the crankshaft sensor was the problem.
View 2 RepliesI put 4 qts Mobil 1 motor oil in, with a new Mobil filter. Drove 400 miles no problem. Parked car a week. Drove car to find CEL on. Can overfull oil cause this? (I heard it can cause lower gas mileage.)
View 11 RepliesMy car has 120.000 miles and regular maintenence done on schedule. Yesterday, after a 1000 mile / 4 day trip, after a break at a service station, the engine srudded violently (for being a prius, it felt like a diesel) while cranking up durin acceleration.
The check Engine light came on.
Using Can-view, I noted these DTC codes: P0101 C3100 P0000
And cleared the memory.
The check Engine switched off.
I go in this week to recheck my nagging check engine light. Flashes after a warm start, then stays on. Been there once already for it, it has come on too after a cold start... Last time they said it was a very vague miss fire code.... It did shake a bit... On the plus I get to drive a nice new Elantra again.... On the down, I never want my car back after driving it ...
View 2 RepliesThis Prius is an '04 with 156k and it will only start with a jump box. I went into the display and found the 12 volt battery reading 12.2 volts after sitting for 4 hours. When driving stop and go around town I will get the red triangle of death and vsc lights but NO check engine light comes on. Using a Scangauge it shows no codes, system ready. I look into pending codes and there is nothing. However when I force clear pending codes the triangle goes away.
It's strange there are no codes associated with this fault. I'm thinking to drive it and not force clear the pending codes and maybe a code will show up eventually but I'm not sure.
Last week, I took my 2006 Prius with 180k miles to Meineke for oil change. They pointed out that my front brakes need work and brake fluid needs to be replaced. I've been told about brakes by another mechanic. Two days later, my check engine light is on.
View 10 RepliesAll most 30 days after I bought my 2009 prius it started having problems with the doors unlocking and also starting. By putting the fog in the slot it would still start. Two months ago it wouldn’t start at all. I thought the battery was dead so I had it jump started. From that point on the car would work put the touch screen didn’t. A month ago the touch screen started working but then the car starting issues began again, all the dashboard lights coming on.
Two days ago I drove the car, turned it off, and when I tried turning it on five minutes later it all the dash lights came on and it wouldn’t let me shift into drive. Last night the same thing happened only after inserting the fob into the slot the dash lights no longer came on, and now the check engine light will come up and that is it. The owner’s manual says: malfunction in the electronic hybrid system control system; in the electronic throttle control system; or the transmission control system. I know what these words mean, but I don't know why this would all of the sudden happen.
Our 2008 Prius has about 111,000 miles on it and the check engine light has been coming on and off for a day or two at a time in the past few weeks. I've seen some things online about this possibly being (1) an electrical connection issue or (2) a inverter coolant pump issue. I've been thinking about taking the car in to a local Toyota specialist to check things out, but I thought I'd check with y'all first.
View 13 RepliesI took my 2009 Prius in to have the check engine light read and they came up with P1121 and recommended I have the coolant flow control valve replaced. I bought my prius used and noted that in the service history, the valve was replaced under warranty in Feb. of 2013, about 40,000 miles ago. I'm going to have the valve replaced, the prius and I are embarking on a 1500 mile journey in a week or so and I'd rather not take the risk of not replacing it.
View 6 RepliesSo for the last few months, I've had my check engine light on my 111,000 mile 2005 Prius going off sporadically. Everyone tells me it's the gas cap, but I've been putting off replacing it because I want to make sure I get something compatible.
View 8 RepliesI have a 2007 Prius that has 112000 miles on it has had no major work done on it just oil changes and air filter now all of the sudden the check engine light is on manual says to take to the dealer asap to trouble shoot this?? Is it serious? Can I still drive?? Do you think it is the in cab air filter never have changed that one?? I really don't have the $$$$$ to take it to the dealer.
View 8 RepliesOur 2008 with 110,000 mi is intermittently displaying CEL. First appeared about 3 wks ago. I took gas cap off and then put it back on and let car sit overnight. Next day and for 10 days no CEL. Then one mornng, at first start, CEL reappeared. Repeated gas cap process that night. CEL disappeared for 6 days. Then CEL came on in middle of day after car had been started and stopped 3 times. Repeated gas cap process that evening with no success. Did the gas cap thing one more time, last night, and today the CEL is off. First time CEL came on was right after a fill-up. Subsequent CEL's have had no relationship to refueling. Car has been nearly flawless for 68 months. Engine coolant pump changed @ 75k. Aux batt changed 24 mo ago.
