I beleive the AC Pressure sensor is the low pressure sensor. Removing it will take the low pressure sensing out of the service. If the compressor is coming on for a breif moment, then you do have a freon pressure problem, could be a sensor but could also be a restriction in the system or as Dr. Hagerty suggest, loss of refrigerant. Need to install guages and provide readings. Some mom and pop shops will charge less than 100 buck to diagnois your problem. If they fix it it will be included in the repair cost.
