Pulled 2 wires out of socket, now SES light
 

i pulled two wires out of a connector when i was doing my intake manifold gasket. The sensor has a vacum line going to the intake manifold off the sensor and a two wire connector going into it. The sensor is on the drivers side mounted on a metal bracket that is attached with the next to the last bolt that holds the intake manifold on. Now it lights up the SES light most of the time and really only goes on during part throttle. I think it is part of the EGR system. Could someone figure out what part this is and how important it is to my car running properly

my car is a 1995 Z28 single cat.

the car seems to run fine, no idle problems, and WOT if just as fast as usual.


thanks in advance

yes it is the egr control solinoid
