Prius (2010-12) :: Engine Off And Key Not Detecting Error?
Mar 28, 2012
I have a 2010 prius. I put in a new stereo system and as part of the process had to disconnect and reconnect the battery. The car drives and the stereo works. However, when I turn the car off and step out of the car with the key fob and shut the door there is one beep in the car and three outside the car and the display reads "key not detected" and it won't let me lock the car with the key fob. It appears to think the car is still running when I leave but it is definitely off. The "key not detected" error message then stays on and will not go off until I go back into the car.
Does the car or key fob need to go through a reset? Is it something I can do myself or do I need to bring it into Toyota? I've tried searching for a fix online and checked the manual and even contacted Toyota and haven't found anything that has worked.

I've been searching a way to read my check engine code WITHOUT a scanner (scan gauge etc...). I have a 2008 Prius and given that there is a lot of things that we CAN program just by presets, it would be surprising if there wasn't a way to read the error codes by some keypresses. Heck, in reality there should be a page on the MFD that just shows the error in english.

My check engine light came on the other day, and I went to Autozone to have the code read. Of course, that indicated the camshaft position sensor was detecting a fault. I read through all the posts relating to the fault, headed up to my local Hyundai dealer, and picked up the oil flow control valve for about $50 plus tax. While I was there, I figured I might as well have them do an oil change, since it was way past due. No point in putting in a new part with dirty oil..right? They did the oil change, washed the car and I was ready to roll. My plan was to replace the part myself, but magically, the check engine light has not come back on since.

I have a Toyota Prius (2010), and the car has run for about 2800000 kilometers. One day when a was driving my Prius the engine light suddenly get on. So I went to a car car mechanic, he checked the car and told me there was an error code (error code: P0401, exhaust problem (exhaust recirculation flow).
So I bought a liquid that I put in the gas tank, the liquid would clean the exhaust pipe, but the engine light was still on. The engine light is usually on at least 2 weeks, then disappear for about 2 days and come back in two weeks…The car is driving normally without any problems.

My 2010 Prius, package IV is only 2 1/2 years old, but I'm at 46K miles.
My factory NAV system has worked fine, but last week when I tried using it, the display said "Map read error", or "Can't read map" (something like that). I ejected the map disc (ver 8.1), cleaned it, reinserted, and got the same error.
My friend also has a '10 Prius, so he let me try his disc. He's got ver 9.1. When I loaded it, the map came up on the display, but the system locked up when I tried to do anything. I had to restart the car, but when I tried again, the same lockup happened with his disc.
Is there anything special I need to do when loading a new DVD map version? Is there any chance it's NOT the actual head unit that's now bad? Is there any chance my dealer would cover this even though I'm over 36K miles, but not over 3 years?

I had to change my fog light fuse tonight, no reason found for that. However, I somehow triggered an error code, P01C1. I managed to reset it, but what this code means?

I leave my car for 2 weeks without driving, and when I start the power, I have check engine light on and I drive to the dealer right away. Mechanic performs diagnostic test for engine misfire no engine miss found. The error code is P0302/P3191. The mechanic told me that I always run the car in very low on fuel, and it causes the 2nd cylinder misfile or not running when the fuel is very low. They suggest me always pump the gas when the fuel indicator has 2 bars left.
My question is that: How come the car cannot run in low fuel, low fuel doesn't mean no fuel, and it can damage the engine/cylinder?

I have a trouble with my 2008 prius; red triangle engine light is coming and when i try to push the gas pedal it feels like it's freeze, the car does not accelerate so I have to stop.
After i turn it off and start again it drives ok, but a triangle is still there and there is error code POA90 ( two different scanners show same code with two descriptions; the first is "MOTOR PERFORMANCE"; the second describe it as "14-volt power module system voltage high").
Specially it happens when i drive up the hill and push the gas pedal harder. What it can be? I took the car to the Toyota dealer; they looked for 8 hours and find nothing; i can't do it again as the car do not have a warranty and the dealer charge for hours.

Bought my 2010 Prius with some issues, most of which are now fixed.
The remaining issue is the mentioned A/C error code: B1498 A/C Communication malfunction (A/C inverter local)
What part this is, and the OEM part number? Where is it located in the car?
Previous owner claimed it was some error with the A/C Control unit.

Three intermittent problems with 2012 Prius Two.
1. Backup camera usually doesn't work but sometimes does.
2. Car 3 times has not gone into start when we press brake and power button. All the error lights go on. We keep trying, and eventually, it goes on and the problem does not often recur. The most recent time this was after stopping for a few minutes after hours of driving, so the battery should have been fully charged and everything warm. fter the second problem, the dealer checked it out, said the 12 v battery was fine and couldn't replicate a problem.
3. Just yesterday, with lights and window washers on, only the Ready light, the Gear indicator, and the headlight lamp were on. Everything else on the display was dark. No speed, no gas tank indicator, etc. Turning the headlights off and on fixed the problem for about 5 seconds, and then it recurred. This morning, with no rain and therefore no wipers, there was no problem, with or without the headlights.

I have recently purchased this 2012 Gen 3 Prius JDM imported from Japan. It is with LED parking lights and HID low beam. At day there is no issue with lights Off, even no issue on parking lights On but as soon as the headlights are turned On i get the fault indicator and some warning in Japanese language on inner screen. Apparently, all lights, on the other hand, are working fine.
When i took the car to repair shop, they installed the diagnostic computer and it showed B2430 and B2431, LED headlight RH and LH, whereas my model is with HID headlights, not LED headlights. At day its ok, i get normal info on inner info screen but at night this error triangle and error message keeps showing instead of normal info and is a cause of fear for me as well because i dont know how serious it may become.

So I bought a 2010 Prius IV from a nearby dealership today. I had test driven it twice before buying, but when I was taking it home I got the error "Check Hybrid System," and the car slowed to a stop. I had to call the dealership to come tow it back and it's being serviced right now. I'm mostly venting, but also more than a little concerned. I checked the orange clip/wire in the back and it was connected properly. What this could be and how big of an issue it really is?

I have noticed that some albums/songs are not being detected by the Entune player that are on the USB drive. I verified that the albums/songs are on the drive. I noticed that it reads MP3 files fine but not MPEG-4 files. One would think the player will recognize the common file types.

So got this P0A93 code when I was driving on the highway about 65mph, scared to me death when big yellow warning light came on so I returned home and turn the car back on after 30 mins the code and all the warning lights were gone I checked under the hood felt the pump everything was good. I just got done 90k maintance on the car from dealer. So my question is that could be computer error or it could be water pump malfunction? On warranty manual the warranty for inverter with converter covers under 100k so dealer should be able to cover the water pump if it's broken? I driven the car today again at normal temperature and full blast AC on, then again no engine check light on and warning light no message.

Check engine light came on. Just over 100,000 miles. Car running fine, no new noises or rough running or lack of power. Wife took to get oil changed next day. Dealer diagnosed as a sticking valve. Personally I would have cleared it and seen if it reoccurred but dealer already special ordered valve. Searching on the p0012 code I see nothing like this.

My car is a Prius Plus 2012.
One day, I decided to go to a mechanic to clean the EGR pipe. Only the pipe, not the whole EGR. It was an extremely simple operation a mechanical one, not electrical etc. Starting from that day, when I go with the car, from time to time, check engine lights up. For a fraction of a second to up to 2 seconds then it disappear.
The car behave itself without a problem. But still the on-off check engine is really annoying.
So a went to the dealer. Put the car on tester.
Result: no code error !
I went to another garage , put another tester on the car, no error..
How can I actually see what the error is if nothing is stocked in the ECU of the car?

Last night I was driving home in my 2002 Prius, and the 'triangle of death' as you call it, went on. I got off the #405 and parked for 10 minutes while I read the manual which said get to a dealer as soon as possible. I started it back up and the engine seemed to be fine but the 'triangle of death' was still there, so I decided to continue to drive but stayed in the right lane.
I must have gone another 20 miles when I suddenly lost engine power, the headlights and dashboard were fine, and hazard lights worked fine. I was able to get to a safe place and towed the car home. Along with the 'triangle of death', the check engine light (little red icon) was on but I didn't get the 'Main Engine' error message.

So I changed my spark plugs, due to an error code saying p0301 which means cylinder one misfiring. I reset the engine light disconnecting the negative battery terminal. Once it reset it ran rough for a few miles. I put about 50 miles on it and it seems better.
