I need someone with either schematics or an R230 to tell me the wire colors/positions that go to the a/c pressure sensor. A rat chewed through mine and I've recharged the system properly and replaced the switch. I had remnants of wires and I've tried a few combinations, but keep getting low pressure and compressor won't come.on unless I force it!
Pressure sensor is B12 on the Driver-side SAM module drawing. AC schematic also posted.
Awesome, so I know I can test that yellow for 5v. However, since the rat got it at the sensor connector, I'm afraid I do not know which pin is which. I had to disassemble the connector and remove what was left of the wires and solder my own wires into it. I've ohmed it out and know they are are all well connected and no shorts exist, but I simply do not know which is pin 1. Most helpful would be someone with one of these peeling their insulation back and taking a picture where they go into the connector. But now with the schematic I do know the order these 3 go in, and presume the 4th is ground. But which is driver side?

Ok so I see from my own picture (taken months ago, I haven't worked on this car in a while) that the plug matches up with the schematic as pictured. I'll verify I have it correct tomorrow and test that yellow for 5v. Thanks again. Hopefully I just have 1 mixed up, can't imagine what else could have happened when the rat chewed this connector...
Could the SAM have a bad sector with a short of that type?
