Good luck
So far so good,fit perfectly but was a real bitch to replace on a 09 Crv. Tried from underneath but couldn’t get to the rear bolt, so I had to go from the top. Poor engineering on Hondas part.

Don't waste your money.
Instead of buying one from the local auto store, thought I'd save money and get this. Bad choice. Installed it and it didn't work. Took it to the auto shop to be tested and they said it didn't work. Cheap imitation of the the real thing.
