Default Re: Door open sensor problem?

No. I've been here since 2009 and cant say I[ve heard of this one before.
But verifying the door switches is simple but not quite "EASY".

Tear the trim from the trunk.
Get to the CLP/SSM module on the passenger side.
Check the voltages at the pins I point to - voltage should change from 'high" (5 to 13 volts) with door open to "low" (about 0 to .1 volt) with door closed.
If you see corrosion and water intrusion on the connectors, replace the CLP/SSM and the last 2-3 feet of wiring harness, do not try to clean or "fix" the old wiring harness or pins. CLP/SSMs are available from "Parts Cars" for $75-150. Do not buy one on eBay, there are many parts cars around, we/I can direct you to one if this goes that far.

Perhaps verify that fuse is OK.
The service manual (which you can download from this forum) has the diagrams and connector pin layout in the wiring chapter.
