Sounds like you have a Baro sensor on the passenger side. It measures atmospheric pressure, and so has no line on its port but maybe a piece of foam rubber (or some remains of it). Someone correct me if I'm wrong.

What fullsizewagon said- one is a VAC sensor and has a line back to the carb/intake. The other is a BARO (atmospheric pressure) sensor with looks identical, but there is no vacuum line attached.
