hello prius people. I am a self sufficient college student with very limited funds. i bought a 2005 toyota prius about 3 months ago at 65,000 miles and have put 15k on it so its at 80,000 miles now. just recently my cars emergency hazard turned on on my dash. i took it to midas for an oil change and to get all the codes read to me. the codes read as follows: ( P300 BATTERY CONTROL) (B2799 IMMOBILISER MALFUNCTION) (p080 REPLACE HYBRID BATTERY PACK) (c1241 Low Battery Positive) (B2775 INTERIOR VEVITICATION) (B1421 SOLAR SENSOR) i started another thread and was told i need to replace the main battery first and foremost. i found a few used ones online for around 700 without the replacement included. i would really appreciate any feedback or guidelines i could follow when buying a battery. my car maxes out at about 20 mph and im not comfertable driving it unless absolutely neccesary. also does the battery have to be from the same year as my car (I.e a 2007 battery for my 2005 prius would work?) thank you anyone who can help i super appreciate it
warranty my friend, reliability of the seller and ease of returning it for another. any year from '04 to '09 is fine. i think there is even a way to use gen III modules. (2010-2015) have you tested the 12 volt battery?
You can use any battery pack from the 2004 - 2009 generation 2 Prius. You will need to ask yourself how long you plan to own the car. Unless the used one you are buying has been recently replaced with new modules, its not likely to be a long term fix. If you are only looking for a few months or so it might be the right solution for you, make sure you have the warranty for those few months. My understanding is many people dont make it out of warranty before problems strike again if the modules are older.
I agree that you should test then probably replace the 12V battery. Then see what codes are left. Check out Toyota Prius: How to Check the 12v Auxiliary Battery Health - PriusDIY.com For the HV battery I'd go a place like Battery4Prius.com in the SF area and they'll give you a warranty with a refurbished battery. It's about $1100 - but this is one of those expensive problems to fix.
First thing to do before buying a battery: Sorry I can't see where you are from while on my phone. By any slim chance are you in a CA carb state that adopted laws in 2004? Was car originally purchased in a CARB state? Slim chance car was originally purchased in last few months of 2005 but worth a chance looking into it. I know someone who just had 2006 hybrid battery replaced under warranty in CT despite law not taking effect until 2008 Darn...such low miles on your 2005. Hope you can find good, inexpensive replacement.
Actually, in your other thread you were advised to replace the 12 V battery (you know, the small 12 V one in the right rear fender) first and foremost. 2005 toyota prius. Emergency light on dash. codes found please help! | Post #5 | PriusChat Why start another thead asking the same question? Were you hoping to get different answers?
your right im sorry. i did happen to get quite a few more responses with a similar result this time but i shouldnt abuse this site
thank you everyone for your responses i highly appreciate it. First thing tomorrow i will check and replace the 12 v. and then take it from there
CALL TOYOTA! Ask for the date your car was placed in service, that means the day the original owner purchased the car. If it is after Sept 1, 2005 you could get a free battery under warranty. Brad
Some have had decent results using an inexpensive motorcycle or mobility battery. Maybe just as a test, since you may subsequently junk the car. I believe the cost difference may be in how venting is accomplished, a minimal issue in my opinion. Others may wish to correct me. Cranking amps is actually more important on the motorcycle than on this car.
