Hey guys I took these photos today from my A/C Condensor and could not figure out what this sensor (or is it a solenoid) does? Can someone kindly tell me what this electrical connector/sensor/solenoid actually does? Does it restrict pressure by any chance? Because I am reading a pretty high pressure on the high side of my system, I'd appreciate your input!!

 

i think its a solenoid, im not sure...umm let me look around or you can use this site for their diagrams they have. Its pretty helpful, it helped me look up a couple of parts.

This is what I got from that site:

80440-SK3-901 SWITCH, AIR CONDITIONING (DUAL) (SAGINOMIYA)

What does that mean? The reason why i need to know this is because I am actually activating my compressor via a manual switch mounted in the cabin along with the condensor fan (my factory A/C wiring is messed up) so what I need to know is if I should attach this solenoid to the switch as well? I wonder if this is the reason why I have such a high pressure on the high side??

 

wait could it be that this is a pressure switch that sends a signal to the ECU to turn off the compressor whenever the pressure is too high??

 

bump for help

 

i think its a high/low switch, shutting off the compressor if the system pressure is too high OR too low. you should have your system properly charged ASAP since overcharging is probably just as bad as undercharging and deceases cooling effeciency

 

Gotcha so where does the high pressure switch sit at? The one that turns the system off whenever pressure is too HIGH?

 

i edited my fist post, i think the switch is both a high/low switch so it will shut off the system is too high OR too low.

 

i don't think that switch has anything to do with hi pressure, since that is handled by the compressor burst disk.

but it is a low pressure switch to prevent compressor damage

 

well atleast you got the part number, ima try askign around to see what anyone knows about this, cuz im stumped right now

 

verbage in both the Honda Part# and aftermarket auto parts site lead me to believe it is a binary switch

from honda
80440-SK3-901 SWITCH, AIR CONDITIONING (DUAL) (SAGINOMIYA)

from autopartswarehouse.com
4-SEASONS SYSTEM MOUNTED BINARY PRESSURE SWITCH -- 28/454 off, 30/300 on;

 

Ok thanks man that solves my problem if its just sitting there monitoring the ref pressure I am good - its not causing a blockage. Thanks!
