rad fans stay on

[Maxo]

Yes the sensor is the correct one. It has been installed for some time now but the fan issues are relatively new.
Does our compressor have a pressure sensor that would cause the ecu to run the fan more often when system is low on refrigerant?

.

nope...

the system has a protection device that prevents the compressor from running enough to prevent sucking air into the system in the event the lo side pressure decreases when the refrigerant leaks out. It can even short cycle the compressor or prevent the compressor clutch from engaging when the refrigeration gas is "all gone"

my vote is for the speed sensor malfunctioning...my fans kicked on the moment I started the car until the moment I shut the car off and my speedometer didn't work. Once I cleaned the sensor, the speedo worked again and the fans operate normally. So I would say pull the sensor and clean it, then plug back in...

where exactly is that sensor?
and my spedo hasnt been working because i havnt been able to get the old one off, stupid plastic housing is preventing me from pulling it off without breaking it

It's on the front diff near the dipstick tube.

Aren't you using a WRX transmission? There is no need to swap speed sensors.

the damn sensor doesnt work, and it has a plastic housin which is RETARDED and when i try to wrench it off it flexes and the wrench pops off

if it doesn't work anyway drill a little whole in the housing so you can stick something through it to break it loose, like putting a screw driver through an oil filter.

hi, i am having the opposite happen with my car i feel my car gets to the point where my fans should kick on but they dont would this be a bad sensor or is a bad sensor when they stay on all the time?

my fans kick on when my defroster are on, but when the defroster are off when idling they dont kick on, when are they suppost to kick in on there own...?

When the ECU tells them to based on a few factors.
