I searched and didnt find an answer on as to what size wrench is required to remove this sensor. It is the one that is behind the intake manifold. I found a post that talks about where it is but cant find information on as to what size wrench is needed. On OZhonda someone mentions a 17mm but my 17mm ratchet wrench doesnt fit (too small) . This is a 2000 s2k. Can someone verify what size wrench this takes?

For future reference : you need a 19mm ratchet wrench to remove it.
