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.
View 2 RepliesI have a 2010 with 4000. miles on it. Check engine light came on. After reading everything I went and checked my fuel cap and yes it was not on. Now the ce light is still on. What next, do I wait and worry or go to the dealer. ??
View 6 RepliesMy '03 Tacoma Prerunner V6 has 116K miles and recently lit up its Check Engine light, returning a code for a failed up-stream air/fuel sensor. I recently drove across country, using many different fuel formulations ranging from CA gas to midwest ethanol to whatever they put in the gas here in the NY-NJ area (a mystery ingredient that seems to turn motorists irate and confuse their horn as a turn signal.)Anyway- age, or fuel, what killed the sensor? If fuel, will it happen again by time I get back west?
View 2 RepliesJust over 6000 miles....Yesterday morning the light came on. Dealer wouldn't look at it for a week. Went to my mechanic this morning to check the code it was p0181 fuel temp sensor. I read something online about the block heater making it too warm. The other night it was cold so I plugged it in, then yesterday morning it got warm overnight like into the lower 40s. I noticed the grill felt warm too. My mechanic cleared it if it comes back on do I have an issue? Is it ok to drive?
View 14 RepliesCheck engine light came on about 2 weeks ago on my 2013 elantra gls. I went to auto zone to get it checked and they ran a p2096, which is what I had almost a year ago. That was fixed by dealer software update. So, I thought that was what needed to be done, headed to the closest Hyundai and they found p2096 and p2196. They replaced the o2 sensor bank 1, under warranty.
However, the next day the check engine light came on, less than 24 hours. Brought it back to the dealer, they said everything was within the correct "parameters" and said the light shouldn't come back on. On the way to work this morning, the check engine light came on, when the car was in the exact same spot it was yesterday.
I'm thinking the computer doesn't recognize the repair and needs to cycle a few times but I don't know. I'm so tired of going to the dealership because they are obviously missing something if the light is still on.
The check engine light came on in my 05 so took my local shop and they checked the code and said it was the Idle Sensor. They were not able to make the repair. Since then the light went off for a few days then came back on. I now notice the gas motor does not turn off when I stop at a traffic light.
View 14 RepliesMy wifes 2008 prius check engine light just came on. Its the control valve sensor. My question is, does that have any serious impact on safety? I've heard mixed on what this valve does (overheating etc).
View 6 RepliesPicked up a new 2012 Prius C a week ago. Check engine light came on. Called Dealership. They said check fuel cap (I had not even used half a tank of gas yet so I did not put fuel in yet) and sure enough it was so loose it almost was off. I tightened it down until it clicked. The question is now....will the check engine light go off on it's own or will I have to take it in to have it re set.
View 15 RepliesLast 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?
View 15 RepliesI recently had someone run a scan on my 2008 prius, which just had a check engine light pop up on it.
It came back with the following code: P1118 MANF. CONTROL FUEL AIR METERING
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.
View 1 RepliesMy 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.
View 7 RepliesI brought my Prius, 128,000 miles, into the dealer with the check engine light on. Runs fine, and checked the gas cap. Toyota dealer said they need to replace 4 fuel injectors, replace oxygen sensor, and clean the throttle body. Check engine light needs to be off so I can pass emission test.
View 8 RepliesI 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?

View 2 RepliesI plugged in a OBD2 reader and its show misfire on Cylinder 1.
I haven't driven the car for 4 days, and when i started the engine this morning, the engine show knocking when the regular engine kicks in (rough). i will be bringing the car in tomorrow (dealer). my car is a 2011 with 16k miles, strange for this to happen so early in age.
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?
View 6 RepliesMy 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.
View 9 RepliesSo 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.
