I've had this code for awhile now (3-4 years), I've replaced the other sensor that's attached to the exhaust manifold up front. I wanted to know if anyone has bought sensors off ebay, for some reason, the OEM/Denso ones are only ~$45, but on other sites like Amazon or RockAuto, it's double the price, are these fake?

I remember seeing a post on one of my other websites...Toyota...where someone bought the ebay O2 sensors, and had problems with them. I got mine at RockAuto, worked with no problems.

 

when purchasing items from eBay, I always check the seller feedback even if the cost is more I will always buy from the seller with the better feedback.

 

Yeah, they're not the "ebay made in China" sensors, they're actually OEM, with the Toyota box and everything. I'm just not sure if they're fake due to the price. Seems like there are several sellers that sell them.

 

Even "OEM" MAF sensors are cheap.

I have wondered about the inexpensive sensors, also. Supposedly they are Toyota/Lexus/Denso, and that's what the photos in the eBay listings will show. At about $45, the price is good for an oxygen sensor, but I don't know how to tell if they're knockoffs.
