Prius (2010-12) :: Check Engine Light Came On?
Feb 11, 2014
Last Fri the check engine light came on so the first thing I did was check the gas cap. It was loose so I retightened it and went on my way expecting the lght to eventually go out. It was still on several hours and a couple of stops later so I called my dealer and explained to my service rep what was going on. He told me to give it a few days and to call him if it didn't go out by today. He said it takes a few days for the computer to reread the system. So we drove it all weekend and it finally went out this morning (Tues). With just under 145000 miles I'm wondering if I should get them to put it on the scanner anyway. It's$130 to do the scan so it's a bit of a ding in the budget. Do the hybrid batts need to be checked,indicator light or not? Here in Ca I think they have a 150000 mi warrenty?

Started my 2010 gen 3 Prius 3 the other day and got a bunch of what I thought was engine clatter and the check engine light came on.
The next time I started it, no noise. Anyways brought it to dealer and they diagnosed it and ordered a new manifold.
The next day when the part arrived, I brought in the car. Talked to the mechanic, a great guy, and he explained what happened. Apparently, the clatter is actually the springs rattling in the clutch mechanism of the starter motor/electric motor and not the valves like I thought.

I have a 2010 gen 111 with nav system etc, the other day a orange check engine light came on, I took it to our Toyota Dealer and they said that I had mud and gravel up in the car, near the fuel intake area, and that the carbon capture canister/switch was damaged by the dirt and I need to get it replaced. I asked if I could simply not make the repair due to the fact that the electronics system would eventually not be able to read the H Carbon readings and the car would burn more fuel.

My check engine light went off last month and when I had it looked at my dealership they said it was due to the seal where the gas cap locks into I believe. Anyway, a week later my light went off again and now they are saying it is the charcoal cannister which I found out is very expensive. Here are my two questions. First of all, can I get this part replaced and installed at a non-dealership? My second question is since they reset my check engine light, it came back on a few days later for two days and then turned off completely. Should the light have turned off on its own? Should I be concerned that it is no longer on? It just makes me wonder if they diagnosed this issue correctly or not.

I installed an Injen cold air intake and 2 days later, the check engine light went on. I had it reset at the dealer and next day, again. Am I stuck with this or is there a way to keep it off, other than putting back the original air box?

Got a 2010 Prius with about 61000 miles on it. Starting yesterday the check engine light stay on all the time (As soon as I started the car). I tried open and tighten the gas cap but no luck and check engine light still stay on all the time. What could be the problem? Will any ODB scanner able to diagnose the check engine light code or need a specific one?

Just picked up a Toyota certified 2010 Prius III....less than a week later, the check engine light comes on. Took it right back to the dealer...in which they said its the air/fuel sensor. Toyota warranty services was closed, so they need to check tomorrow if its covered by the remaining warranty or not.

My check engine and red triangle light came on. I checked the code and it's a battery issue. The code is P0A7F. I called the dealer and they want me to bring the car in for a check.
I'm afraid it will lead to me replacing the battery. I have about 117,000 miles on the car. They have a service bulletin open on this code but I may have exceeded the 100,000 mile limit.
If I do need to replace the battery are there any improvements I can make in this area?

My 2010 Prius with 72k miles on it. I bought a OBDII scanner and read P0401 Exhaust Gas Recirculation Flow Insufficient Detected. The check engine light comes on for few days, then go away for few weeks and then come back again. It's been doing the exact same thing (Come on for few days and then go away) in last few months. But I do not feel any different in terms of driving.

So my 2012 plugin was parked for about 3 days, and when I turned it on, heard loud knocking and the check engine light came and stayed on.
When switching the car on or off, I'll hear two taps/ticks that were not there before. Loud knocking is not there now.
What can the issue be? It was very cold and snowing.

I was driving my 2010 Prius on the Highway (less than 2 miles) and the engine check light came on.... shortly after the ! (triangle with exclamation light came on and then started flashing). I exited the highway and was going back home. On the way home, I noticed a decrease in acceleration and then a message 'Hybrid...'
I was able to coast into an apartment complex and then got a ride home.
After about a couple of hours, I went back to the Apartment Complex. I reviewed the manual and one of the options was to check the gas cap. I filled the tank up last weekend and haven't driven it since today.

Gen3 Prius. Once it turned 100k miles I took it in for an inverter coolant change per the maintenance schedule. The dealer charged $109 for this and the car had absolutely no issues prior. Got the coolant changed on 7/23 and then drove it short distances in town for two weeks with no issues. Once I drove it on weekend longer road trip got a check engine light P0A93 "inverter A cooling system performance". Shortly there after started getting hybrid overheat alerts and pulled over to let it cool.
I checked the inverter coolant reservoir and it was still above full. After letting things cool, I turned it back on and listened to the water pump. Seemed to be running fine, heard it clearly with my ear up to a long screw driver, touching the pump. Noticed that the hose leading to the pump was vibrating but the return hose out of the inverted was not. Also no turbulence in the reservoir. My guess is that they didn't bleed air out of the system.

My Prius just reached 200000 km this week. I bought it at 180000 km 2 years ago, I don't drive it that much simply because I work from home.
Today, a sunny day, 0 degrees, the check engine just lit-up. I opened the hood and checked fluid levels, all OK. I started it and listened to the engine, running as usual. However, when the motor stopped (hybrid ON), I can hear a high frequency noise. I don't remember hearing this noise, but I don't think I ever opened the hood with the engine Off but powered On.
How can I get the check engine code ? I assume I need a connector, right ?

2012 Prius Gen III 38,000 miles, check engine light came on. Drove car to dealer and they came up with error code 0456. The explained that a rodent (I live in a rural area) chewed on a hose which is causing a leak like a bad fuel cap.
To solve this problem they recommend that the entire gas tank needs to be replaced. Does this seem reasonable? It seems to me they are saying that the chewed hose can not be replaced.

I'm due to leave at 6am sharp on Friday morning for that pre-planned surprise 50th Bday celebration I've been talking about for my wife. This evening I get in the Elantra to pick her up and when I started the car it began to shake VIOLENTLY, like I was in a commercial dough mixer. WTF!?? I saw the check engine light was on so I shut it off immediately. Curiously, I had the car out earlier without incident.
I restarted the car and it ran smoothly this time, but the check engine light remained. Calling the dealer, I was able to get a 9am appointment for tomorrow morning. I don't have an OBD-II scan tool to check the codes, but based on the symptoms, and recent poor gas mileage.

So the check engine light on my '12 with 5K miles came on 2 days ago. Called to make an appointment at the dealer for tomorrow...and today it goes off. Is it relatively safe to fore go the appointment and see what happens? I don't think it was related to the gas cap.

I just bought a used 2011 Elantra GLS and am having some issues that the dealer cant resolve. What is happening is the the Check Engine light comes on and off. It will be on for a day or so, then go off for a day or so, so I am thinking its the gas cap. So I tighten that thing up as good as I can and pulled the negative battery terminal and problem solved. About 2 days later, and about 200 miles later on the same tank of gas, the light pops back on. So I call the dealer and took it there the next day.
On my way to the dealer, the light goes out. They try and pull the code, but the ECU is showing nothing. I asked if the ECU stores codes and I was told that when the light goes out on its own it clears the ECU of the code. Not sure if that is true, but that is what I was told. So I drive the car home. I fill the car with gas, drive about 100 miles and the light comes on. I call the dealer the same day, take it over, and on the way like the car knows it goes off and guess what? Dealer cant do nothing.
Now to make a long story longer, this is what I know. The car is not a CA car. It was sold in GA and was a prior rental. It ended up in CA and was sold as a certified pre owned from a Hyundai Dealer, I actually bought the car from a Mitsubishi Dealer and they dealer traded for this car (thats another long story) the carfax does show that it failed emissions but passed after several attempts. Which I thought was odd on a ULEV vehicle. Since I liked the car so much and the price was good, I bought it since it did pass smog eventually.
Once I get the car home, I do my usual thorough look. I clean everything to my standards. I am cleaning the engine compartment and took the engine cover off. 1st thing I noticed was the Spark Plug Coil Packs all the 10mm bolts that hold them in were loose and 2 of them were completely off!! So I decided thats odd, so I pulled the plugs out and they were the NGK's so just in case I put a brand new set of the NGK laser Iridiums back in and tighten everything up. Then I notice where the PCV valve is on the valve cover, the hose that goes to that to the intake tube does not look stock. The hose looks like fuel line hose that someone put on it and the clamps are not stock. So I am canvasing for OEM replacements of those parts now. Then when I was installing the mud guards, on the drivers side rear tire where the gas filler tube is I notice another non OEM clamp. So someone was messing with this area of the car too.
The car is averaging 26-28mpg's in the city and I have been getting 35-37mpg's highway so I don't think there is anything major wrong here. I believe that either the PCV valve hose is kinked and may be causing a fault, or that since it was a prior rental that people were over filling the gas tank and maybe blew the expansion valve in the gas tank, causing the fault. I have no way to prove this since the light goes on and off and clears the ECU every time I take it in.
