First on all I would like to say i am not a honda guy, I am just helping a friend out. We swaped a d15 for a zc grey plug.(I guess) well on the d15 where is one more sensor then the zc. and we are getting a check engine light and it boggs of the line. I included a pic of the sensor. The new zc motor dosnt have a spot for this sensor. What do we do? What is this sensor called? Thank you I am a noobi.[IMG][/IMG]

 

Its called a Purge Soleniod valve, I think.

 

do I need it? what should i do
