refrigerant temperature sensor

[kksh]

Hi,

My car's ac is only blowing normal air. I ran a diagnostic and gave me an error 27 refrigerant temperature sensor and it's sensing -30 degress.

I'd like to know where that sensor is located at cos I can't seem to find it. And any has any diagrams of the AC control unit? thanks

I'd check your fuses first.

[kksh]

I have and the fuses are fine. The AC control unit isn't sending out a signal to start the compressor because it's not getting the signal form the refrigerant temperatue sensor.

Fair enough. I have a similar problem with the PBR sensor showing an error and its because a fuse keeps blowing. Unfortunately the picture of where to test the sensor in the R32 Workshop manual is too dark/bad to work out where it is

so can you like give general directions as to where it could be? No idea? Is it along the refrigerant line or inside the dashboard or the engine bay? Will it be possible for you to give me that page of the R32 workshop manual. And what is a PBR sensor and where is that located at?

[lwells]

No idea, sorry I would think its somewhere near the compressor, but really I have NFI.

I have extracted the Air Con section from the workshop manual for you (Right-click, Save as) here

Thanks a bunch. I found the sensor. I used FAST to locate it. It's behind the condenser or whatever you call it behind the glove box. I couldn't get to the sensor without taking it out and having to regas it so I just cut teh wires and put on a resistor. Not sure if it's the right value. Can anyone point out to me what the diagnostic shows when you run it in mode 5? Mine shows 24.5 for the refrigerant sensor now. So it's working but not sure if it should be that value. Thanks

I'm goin to get mine converted and refiled tomorrow.

Mine shows some very weird values in Option 5. Some of the values are like -20C

I don't get any error codes.

Approx. what numbers should read when normal?

Outside Air? Inside Air? Suction Temp? Refrigerant Temp?

nedb: the recommended ranges are the workshop manual section I linked above. Its only about a 600kbyte download so I suggest you grab it
