Prius (2001-03) :: Check Engine Light On Then Goes Off By Itself
Jun 13, 2011
I have a 2003 Prius that I absolutely love! I have just under 82,000 miles and it only had approximately 95 miles on it when I leased it in Feb. 2003. (I'll never lease again!) So, when the lease matured, I didn't want to part with it and the car's been basically problem free. Just the standard oil changes, tire rotation, replacing tires.
On Friday, June 3rd, my check engine light went on, I immediately pulled over, checked the dipstick, but all was well. I drove carefully/slowly home since according to the manual it states, "take to dealer."
On Monday, June 6th, I took it to the dealer and paid $110 for a diagnostic fee and was told: "You have a malfunctioning sensor in the tailpipe which is stuck in the open position and it will cost $1500 to replace, wish I had better news for you." I asked what would happen, would I still be able to drive home, would the engine blow up, etc. All the service manager said was, "Well, it will affect the performance of the car and the gas mileage."
As of Friday, June 10th, miraculously the check engine light went off by itself and has not come back on. AND it has NOT affected my gas mileage, I'm getting anywhere between 48-50 mpg, which is what I usually get!

today my check engine light turned on. I opened the hood ( Not like I know anything about cars, but doesn't hurt to look for obvious stuff I guess) and there was a bubbling sound. I followed the sound to what I think is the inverter pump? It's like a tank smack dab in the middle and has a pretty thick tube coming out. The liquid inside looked to be bubbling or boiling. Is this normal? I've checked the gas cap and tightened it and restarted it so I don't think that's it. It's at about 160,000 miles.

I have a 1st gen prius. Got the triangle and check engine light which is p3006... I checked the battery all cells are above 7.5. I notice the inverter coolant is low which I'm adding some today. Even tho it was low is it supposed to be moving or is my pump out? i did not see the waves or bubbles at all.

I just recently purchased a 2001 Prius with 92,000 miles on it and the check engine like comes on frequently. I have a scangauge and I scan for codes and it comes up P0000. I clear the codes the light goes off and everything seems to be ok. I'm not even sure where to start "looking" for something to be wrong.

I have a 2001 Prius with about 175K miles on it. I was headed to the beach this past Tuesday and had an oil change done right before I left. The trip here from NC to Myrtle Beach was about 200 miles. On the way back today, after I stopped to fill up on gas the 'check engine' light came on for the rest of the trip back home. I went tonight to Autozone and got back all the codes that are P0420, P0300, P0301, P0304, P0440 ....
My question is...Is it possible that all of those codes are somehow the result of my recent oil change? (Oil overflow?, etc.) I've been doing some searching in the archives for those codes and oil/fluid changes appear to be a possibility with all of them.
Just a little background, I've already had the hybrid battery replaced in this car a little more than a year ago. I've had no more warning lights come on since that time until today.

This has been a very good car for us. We've had it since '03 with 30k. Problems have been minimal, till now. The 'check engine' light came on several months ago, and we were unable to afford the repairs. We used it as a 65 miles per day commuter car, mostly at highway speeds. The mileage has dropped off abruptly from the long-term 42 mpg down all the way to 24. There is a nasty vibration on startup. It lasts for maybe 30 seconds and then calms down. We are now at a place where we can do the repairs.

I have a problem with my 2002 prius. I was driving home from work when all of a sudden my Hybrid Warning light came on with the check engine light on. On the screen, it gives me a (PS, Battery, and ! ) and the "!" was the one lighting up. The engine was roughing up sounds like it was gonna stop itself so I pulled over to the side and it turned off by itself without me doing anything except to put it on park. Then, i took out my keys and tried restarting it and all i heard was the "Ready" beep but not the engine and it won't move when i step on the pedal. After waiting for 10 mins., i tried restarting it and it worked i drove away and got home safely with all the warning lights i mentioned earlier still on. (Note: i was driving w/ the A/C on because it was hot outside..around 90s, also it was not overheating nor it was any battery problem because all the electrical were working properly.)

I only drive my car once a month or so to visit family. A few years ago my 12v Battery stopped working in my car. I assume age and just moving my car from one side to the other every morning contributed to this. I got the battery replaced at my local Toyota dealership in Jan 2012.
In early March of this year my 12v battery died again. I jump started my car every morning (with a portable battery pack) until I was ready to drive it a distance a few weeks later. I got about 2 miles and then my check engine light came on as well as my Hybrid System Warning Light.

I have had a 2002 Prius since December of 2012, and it has been running fine since I got it; while it was in a wreck in May 2013 that has rendered both passenger-side doors and windows unusable, I have not seen that incident cause any other problems, and the car still runs perfectly fine. I am supposed to be driving from my current home state for a job soon, but about a week ago while I was driving on the interstate, the check engine light started flashing.
I was changing lanes and putting a good bit of pressure on the gas in order to pass someone that was going below the speed limit, putting my speed at around 80 mph when the check engine light started flashing. I started getting off of the interstate to find a place to stop and inspect things, but the light stopped flashing when I got down to around 45 mph on the exit ramp, and I was able to drive the rest of the way on the interstate without any trouble, even when I got in the 75 mph range again. The span of time between the light starting to flash and turning off again was probably about a minute or so.

My wife's Prius now has the check engine light, the orange triangle, and the car with the exclamation point lit up. It only has 96,000 miles and hasn't been in a wreck that we know of. I've read that it has to do with the HV ECU, but I don't know much more about it. Is there any chance it's just a loose cable or something simple? It doesn't seem like her car should already be having so many extensive problems all at once. We haven't had any in the past, except the car with the exclamation point came on for a few days and then went away on its own.
Codes: P1636, P3106, P3002, P3006. It's a 2002 Prius

Suddenly today, I get a "Check Engine" light while driving. Scangauge II says it's a P1430 error. I found two different suggestions, but where these are located on the car.
P1430-Electric Air Pump secondary Failure
P1430 -Vacuum Sensor for Adsorber and Catalyst System Circuit Malfunction

I was driving my trusty 2002 152K miles, and came into a very long and very slow traffic jam on the side of a mountain. After about two hours of mostly stop and very little go, my CEL light came on. I am also seeing the "general fault" symbol, but it should be noted that my PS symbol has been showing for about a year because my PS died and I just didn't fix it.

I have a 2002 prius with 143,000 miles. On Friday, I went to start my car and put it in gear and the check engine light came on and the "triangle of death" lit up and car died. I turned it off and waited about 30 seconds and tried starting it again. It started and I drove 1/2mile home. Went into the garage and got the Actron/OBDII code reader. Pulled the code P3125 which when I googled it, it was referring to the inverter. I cleared the code and all was well.

My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.

I have a 2001 Prius with 210,000 miles. The inverter and traction battery were replaced last year. I started getting triangle and check engine lights about a month ago and the scan tool read p3191 p3006 p0300. The car would barely start in the mornings and the dash lights would be dim. I replaced the 12v aux battery today and all the symptoms went away. Driving home the triangle/check engine light popped on again and I stopped at Orielly's to use their scan tool. It now only reads P3006. I called a local mechanic who suggested to drive it a bit and clear the codes because the battery needed to equalize. Is this true?

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.

I 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.

While I am driving the car it will start to die and skip. Happens randomly. Today I was driving up a small hill and it went quits on me started lurching with check engine light coming on and off. The car will turn over and start, but only for a few seconds before dying again.
Seems to happen when the car is running for a while. Also the ABS light flashes on then off randomly while driving sometimes although It hasn't been an issue. Will be checking tomorrow to see if it starts.

I have had a check engine light on in my car for a while now. I am pretty sure that it deals with the disconnection of the vacuum servo that controls the intake manifold's flaps that designate which track the air takes through the manifold. It has been running fine like this for a while under the assumption that because the performance of the vehicle hasn't changed, there is no need for immediate repair.
Here is my new problem which I am trying to determine if it has to do with the above issue. Over the past few days my car has been giving me EPC and ASR lights along with switching to back-up power. I have been on expressways driving 80, i have been going around corners doing less than 20, and it has happened everywhere in between. Keep in mind that when it happens i slip my car into neutral, pull over, and reboot. After that everything is fine for a short while. I stopped at Auto Zone to get a diagnostic, and for some reason, which i did not feel like questioning due to the way the autozone employee was mentally equipped, they did not give me codes, but descriptions.
(1) Camshaft Positioning Sensor Fault A Bank 1
(2) Camshaft Positioning Sensor Fault A Bank 2
(3) PCM Processor Fault
(4) Running too lean on Bank 1
(5) Running too lean on bank 2.
These are the descriptions for the 5 fault codes. I am planning on stopping back today and getting the proper codes. But would like to get some opinions in the mean time. I've check fuses and relays pertaining to this issue and all have tested ok. Nothing is leaking from my engine and nothing is visibly damaged, except for the vacuum servo arm which is broken (see above paragraph). I feel like the issue is with the ECM (PCM, PCM, ECU, whatever).
Another interesting thing is that when i operate my car using the cruise control, there are no issues what so ever. Possibly an issue with the throttle or its many components?

I own a 2001 Jeep Cherokee with 104,000+ miles. It runs great and doesn't have any issues. However, i started it up this morning and the check engine light came on. Should this be concerning? I haven't done any real maintenance on it since it runs so well. And i guess that's my other question - what should i do to the Jeep to keep it running for another 100,000+ miles? Spark plugs? Timing belt??

I have 01 passat, it runs fine, except check engine light is on. When I turn AC on the engine beginnings to work funny, RPMs jumping up and down, feel like engine doesn't get enough air (or gets too much). I was told to replace ignition coils. I replaced them all but the problem didn't go away. Even actually one of the coils pups up a little bit all the time.
