    I am replacing an 89892-47080 sensor in my HV battery pack. I ordered what was supposed to be a new 89892-47080, but upon arrival and opening the package, I was sad to see it was an 89892-47020.

    I understand that 89892-47080 replaced the 89892-47020 in or about 2012.

    Of course, I wonder why Toyota would need to replace a functional and working part, that looks the same and performs all the same functions unless the newer part was cheaper to manufacture and/or the newer part corrected a weakness that the original may have had.

    I'm just a little perturbed at the seller sending an older part when I did not haggle on price and passed up on purchasing less expensive used 89892-47080 sensors and much cheaper 89892-47020 sensors.

    But....I do have the 89892-47020 sensor and I wonder what problems I may have if I install it, now, or in the future, that I would not have if a sensor 89892-47080 had been used?

    Sometimes they make updates to the parts. There may of been a defect in the
    manufacturing and or they changed the tolerances.....
    You can alway contact the place you got it from and ask for the newer part number one....

    I was just want to have one of them installed and working until whatever I'm going to do track down another updated part just because or leave everything alone and let it rip.

    I see no indication from you, or from my direct installation experience rebuilding battery packs that there is any difference in these two parts just because the last two numbers are different. Just put it in and your done. There's no difference between these two other than date of manufacture and perhaps some minor tweaks. There's no reason to think this won't work...

    Thanks Everyone;

    Still looking for the Reason Toyota went to the 89892-47080 sensor.

    ASRDogman, I agree, but the issue of a seller sending an older and less expensive part when a newer part design is called for and having represented the item with a picture of an 89892-47080 sensor, in my opinion, is a fraud. This leads to the value of the reason Toyota changed the sensor 89892-47020 to an 89892-47080. Once discovered, a better-reasoned course of action can be taken.

    Tombukt2, I agree with you as well. Be it as it may, as a mechanic, a general contractor, and everything else I have done in my life, I have had an aversion to having to do something twice, when once should have been enough. I'm in a position where I don't have to have the car drivable at the moment.

    PriusCamper, Actually, I am not questioning 'if' it will work, it has been my understanding that it will. My goal, is to find the 'reason' Toyota went to the 89892-47080 sensor
    and made it the replacement for the 89892-47020 sensor. Is the 89892-47020 the exact same as the 89892-47080, I doubt it.



    It is possible that Toyota went with a less expensive chip, but it performs exactly the same, but with the change, it required a new part #.

    If I knew that, then I could make a better-informed decision.

    The fact I purchased a new 89892-47080 sensor but was sent an 89892-47020 sensor, without me agreeing to it, just isn't how I like to do business.

    Thank you all - I truly appreciate everyone taking the time to express your opinions.

    I don't care if I have to do it 20 times this is one of those things that plugs in and at least I have a part to plug in and drive now so later after I get done suing everybody and claiming that I've been shiested out of whatever. And finally get the right part then I can throw it in when time comes which may never come because the one I put in there that I'm bitching about and working flawlessly and the car nobody else cares so there's always that if all of these things are the facts then you should be able to ring the seller up or whatever it is you do these days and haven't fixed that for you I know that most of the people I deal with do just that bring the dude up go through the spiel and tell the dude yeah I want the part numbers it ends in 4450 or whatever it is and I'll be standing by thanks then you've got to send the one back to him and all of this and that but yeah in the interest does not having to do anything again I guess certainly but during that time of interest what are you riding around with no part on the car or?.

    I agree 100%. You did not get what you purchased. Every revision is going to have a slight change or update. Could be small or big, could be super minor or important. Even the Gen 2 HV battery ecus have 5 or more model numbers, but are all interchangeable. BUT, if I purchased the latest revision, then that's what I expect to receive in my package. The latest revision is also going to have the newest manufacturing date.

    If you bought a 2015 prius and the dealer handed you a 2012, would it be ok?

    Buying online is problematic in this regard... My understanding is that as long as hardware with a slight change in number is compatible/interchangeable then they sell it to you. And if you want the exact number that would be a request greater than the basic assurance it will work, which many sellers would consider unreasonable online, but probably not in person in a shop where they can go through the inventory to be more helpful to your request. That doesn't ever happen online.

    As always, if we were talking software and not hardware you'd likely be able to find a list of what updates were done in each iteration and you'd be able to decide which version is best for you, but hardware doesn't play by those rules, so it's hard to know what you're missing out on.
