Re: what sensor is this. *pic*
looks like an evap sensor/system possibly, hard to tell completely from the pic included. does small rubber hose attach to the nipple on it?

that is defiantly the evap purge solenoid. I used a junkyard SOHC to put on my b16 cause mine was broke. Didn't notice a difference with or without lol

Basically, there's a valve in the fuel tank that releases fuel vapors into the charcoal canister. When the pressure gets high enough, it opens the evap purge valve and allows the fuel vapor to flow from the charcoal canister into the intake manifold to burn. The catalytic converter then cleans the exhaust, thus reducing emissions.
It's for emissions purposes because it's generally considered bad for the environment to vent fuel vapors into the air.
On a USDM OBD2 ECU, it will usually throw a P1456 or P1457 code if it's missing or functioning incorrectly. You may also notice an increased risk of overflowing the tank on fillups.
