    After market product. Pretty good value. It works.
  

*by K***R on Reviewed in the United States on October 24, 2019*

This is after market. Pretty good value for the money. We put this on a 2002 Toyota Tacoma 4x4. The sensor seems to be working.  Our check engine  light went off and has not come back on. We no longer have the miss and jump when shifting or driving. The picture shows you are getting a gasket with this item. We did not. I contacted seller and they responded that it was already attached to the product. Ours was not. We had to use the old one which was still good.
