AC sensor and connector removal

[Elvis_Presley]

The clutch won't engage on the compressor, and I'm trying to figure out why. The last (I think) thing need to check is the (low pressure I think) sensor behind the intake tube. Can anyone tell me how to remove this connector? Also if I remove this sensor, will there be a valve that prevents the Refrigerant from leaking out (like on the sensor next to the compressor)?

There should be a small tab you press and hold in to release the electrical connector to the sensor.
The tab may be on the back side of the connector to can not see it too well . . but feel for it or use a small mirror and flash light to view it from behind.
Also, I just read on another forum of someone replacing that sensor and it has a Schrader type valve behind it so no refrigerant should be lost when changing it.
I did read to check an o-ring on the new sensor and make sure there is one or replace it with from the old sensor after cleaning and lubing with a very light film of silicone grease or fluid.
Also, it says not to over tighten the sensor. It should just be snugged down since it is the o-ring sealing the connection.
