Prius (2001-03) :: Does The Immobilizer Only Check The Key At Engine Start?
Sep 1, 2014
I have a 2001 Prius and my wife has a 2001 Highlander. I only have 1 master key remaining for the Prius, and both cars use the same transponder type. I had a plain (metal, no transponder) copy made for the Prius, and it turns all the locks just fine. I also followed the master key programming steps with the metal non-transponder key in the ignition, but holding the Highlander key in close proximity to the ignition. It worked! If I have the highlander key on the keychain next to the metal spare Prius key, the Prius will start. The Highlander key is now a 'superkey,' it will start the Highlander, and it will also pacify the Prius immobilizer.
But this is not 100%; if it doesn't sit right on the keychain, I sometimes have to hold the Highlander key a little closer to the ignition to get it to recognize. I

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 2000 Jetta VR6 and my Immobilizer (car & key) dash light came on, along the check engine, battery, and a few lights when tried to start my car to move it. I've been doing my research and know the problem is the communication between an RFID chip in my remote key and the key cylinder. My current remote key is old so I wonder if I need a new key. Now I do have a spare remote key (hardly used) and valet key which I could have overnighted to me.

I have an 06 Prius. I bought it with a broken/leaking transmission about 3 months ago. I drove the car home and it sat for a few months, then I drove it into my garage to start working on it a few weeks ago. I just finished up with the trans swap this evening and I went to "start" the car to get the coolant circulating/blead, and the car would not start. I get nothing, I just get a blinking red light in the shape of a car with a key in the center.
I am pretty sure this is the immobilizer symbol. What can I do to reset/fix this? This is my first prius and I have not driven this one more than 50 miles so it could be something silly that I am just not familiar with. This is what I am doing...I get in the car, put the key in the key slot, and I push the brake, then I hit the power button...I get nothing, other than the blinking light on the dash.
I went back out to the car and messed around a little bit. When I put the key in the slot I get what I described above...nothing. But if I don't put the key in the slot, and just push the power button the display comes on but I am not able to shift into any thing other than park or neutral. When I am able to power up with out the key in the slot I get a red car with an explanation point going through it at the top left of the screen.
Then at the display just below the windshield most of the lights stay lit up. What does this point towards? Why would the car not try to go into Drive or Reverse? And what's going on with my key? The only two times I have driven this car i just put the key in the slot and it turned right on and I drove away, now with the key in it will not do anything.

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.

Recently there has been a series of problems popping up with the Prius. Its a 2003 model year.
- About four nights ago the warning icon and check engine light (picture below) popped up upon engine start-up and i noticed a weird idle. It seemed to idle rough. After about 20 seconds of idling the engine would shut off. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.
- The afternoon after that the same warning icon and check engine light popped up along with the rough idle. After about 10 minutes and 6 or 7 attempts to restart the engine the warning lights disappeared and idle seemed to be restored.
- After this incident it seems like the vehicle is getting bad gas mileage. The picture below shows me getting an average of 25mpg. I was driving very conservatively. Driving the same way i usually do, i usually get 45-50mpg. The vehicle seems to be charging the battery more than usual.

This issue has only happened twice to me.
I go out to start the car, it cranks and cranks and cranks. I stop turning the key. I then try again and it hesitates to starts. I give it a little gas and it starts. When it does this, the car begins running very rough and idling rough. When I give it a little gas while it's parked, the check engine light begins flashing at me.
I turned the car off and came back to it the next morning (maybe 10 hours apart). It started right up no problem, no CEL either.

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.

Toyota read the codes wrong and told me that I need a new hybrid battery. That is incorrect info. Codes P0300 P0301 P0302P0303. The codes mean misfire in cylinders 1 , 2 and 3. I have had injector cleaned in the past new spark plugs. If I drive it it gets warmed up and shuts down. It will restart and run maybe 7 more miles the same. The brake light comes on and I have to restart it.

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.

My daughter 03 Prius died on her, the codes it threw are listed as P3108, P3191,P3101. We cleaned MAF and throttle and this did not solve the problem. We replaced the MAF with a remanufactured unit from O'Reilly's and now the car drives normally, but the check engine and red exclamation light are still on.

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.

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.

Recently, my check engine light blinks when I start my car. Once I put the car in drive or reverse, it turns off. The light does not come on when I put the car back in park. What this means?

All most 30 days after I bought my 2009 prius it started having problems with the doors unlocking and also starting. By putting the fog in the slot it would still start. Two months ago it wouldn’t start at all. I thought the battery was dead so I had it jump started. From that point on the car would work put the touch screen didn’t. A month ago the touch screen started working but then the car starting issues began again, all the dashboard lights coming on.
Two days ago I drove the car, turned it off, and when I tried turning it on five minutes later it all the dash lights came on and it wouldn’t let me shift into drive. Last night the same thing happened only after inserting the fob into the slot the dash lights no longer came on, and now the check engine light will come up and that is it. The owner’s manual says: malfunction in the electronic hybrid system control system; in the electronic throttle control system; or the transmission control system. I know what these words mean, but I don't know why this would all of the sudden happen.
