Here's a long overdue follow up for those who find this thread looking for answers... I called Lucky8 about my issue and they sent me out a replacement compressor right away which fixed my issue. I read in another forum to test the resistance across the temp sensor and found I didn't get a reading across either sensor, my bad one or the new one.

Props to Eric at Lucky 8 for fabulous customer service! If you guys haven't done business with them yet I highly recommend them!

 

Thanks for the follow up post, as I’m getting the same code consistently. Can you test resistance of the switch with the compressor in place, or did you need to pull it out? Maybe you can post a link to the other thread you referenced as well.

Just to clarify, the newest compressor you were sent did measure correctly before you installed it?

 

Morning, any insight on weather the temp sensor can be repaired / replaced on its own?

 

 

I had the same fault code, and measured 0.4 ohms at the temp sensor pins on the connector. That of course is out of range for the sensor and interpreted by the controller as a very high temperature. I ordered a replacement compressor assembly. Looking for a "keep it on the road" temporary fix I tried cutting the voltage input wire to the sensor. That gets you about 20-30 seconds of compressor operation before the controller notices that the temperature value is not changing, stops the compressor, and throws a code. That code does not latch however and you can get another 20-30 seconds by turning the ignition off and back on. Not a good plan in general but may be useful under certain circumstances.

When I removed the failed compressor I decided to inspect the temperature sensor. I cut the remaining wire from the connector, pulled them from the harness, and unscrewed the sensor itself. It is completely sealed in its own metal housing with a rubber boot around the wires. Upon removing the rubber boot and re-measuring the resistance I got a shock (no pun intended): no short. The boot is attached in a way that routes the wires over the metal collar and apparently that had worn through the wire insulation over time. I changed the routing through a newly-created hole in the top of the boot and now have a usable spare.

Seems like a good thing to have given the catastrophic suspension failure that follows when the sensor fails.

 

This suspension failure doesn't seem catastrophic to me. As long as it can be cleared....you just clear it and then pull the EAS fuses to get yourself home.

 

Well, yes, catastrophic may be a bit dramatic. However if you need a working compressor to get home you're out of luck. No combination of fault-clearing or fuse-pulling will get it working in this case.
