What is the difference between sensor 89892-47020 and 89892-47080

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?

 

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.
