Prius (2004-09) :: Check Engine Light Has Been Coming On And Off
Aug 9, 2016
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.

My check engine light has been coming on and off and it seems to show P0420 for catalytic converter. The light stays off for about a week and it'll come on for a day or two and off again.
Wouldn't a failed converter stay failed? Can P0420 be triggered by loose/bad gas caps?

I have a 2004 standard Elantra GT. I had to get an emissions test and the CEL light will not stay off. My garage replaced two valves in the fuel tank and the neck to the tank and have done numerous "smoke tests" but can't find the leak. Now they are saying there is something wrong with the computer. They got it to stay off long enough to pass the test, but the light's on again. I see that there was a recall issued because of the cracked exhaust manifold, I think I had the catalytic converter replaced up at the cottage.

I keep failing my emissions because my check engine light keeps coming on. I was told that the problem was the catalytic converter rear and needed to buy one for both sides. The problem I am having that I don;t know which Catalytic Converter I should buy. I know without it is causing my car to stutter. Which I should get?

I have a 2004 Accent GS. It is an automatic. I have had it for almost a year.
In early November, the check engine light came on when the temperature dropped drastically and it went off when it warmed up a bit about 3 days later. Since then it seems to come on randomly and stay on for a few days then go off (usually around once-twice a month). Then in late December I noticed that the car had trouble starting after I refueled it, the first two times I though it was because I had let the fuel get down too much. Now every time I fuel up it does this. But just the first time turning on the car and no other time after that.
The check engine light had not come on again for almost a month, and then about a week ago it came on again. I double checked all the fluids and the gas cap but that's about as far as my knowledge of cars goes. When the light has come on I have not really noticed any handling differences. However since I need to put the car through an inspection very soon it is now concerning me a bit more. What could be causing the check engine light to go on and off?

2004 Audi A6 2.7 T quattro ... Check engine light comes on and three mechanics all say i need new torque converter even tho i have no symptoms as yet. Will I get symptoms eventually, or could this be an electrical issue. When they turn off the warning light, it takes a day or so to come back on. There has been no reduction of mileage, no gear slipping, no problem accelerating.

My car's an 04 Mitsubishi Lancer ES, 4-cyl, 2.0L. So long story short, my check-engine light has been coming up every now and again for the last couple months with the code P0421, which a shop has confirmed I need a new manifold catalytic converter for (they ruled out any problems with O2 sensors).

My wife's car is a 2002 Prius, 149 k miles. Lately the check engine light has been coming on. I took it to the dealership, and their assessment is that the catalytic converter needs to be replaced. They are recommending about $2,000 + of repairs. While I am contemplating the practicality of investing that much in keeping this car going I'm wondering if it harmful or dangerous to continue operating this vehicle.

I have a 2003 Prius, I had an accident and after it was fixed the check engine light started coming on. It would go off after a couple of days. The first time I took it to Autozone and the codes were P3150 & P3130, but the next day the check engine light went off. A couple of days later the light came back on....went back off....next week it stalled on the highway, but it started back up, now the codes it's reading are P1636 and P3002. It still starts up and will drive, but I'm afraid to drive it.

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).

I 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?

I 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.

I 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.)

My 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.

This 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 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.

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.
