Here's the "skinny"
Once again, you are dead on. I have the ALLDATA sheet the inde printed for me in my hand right now. It is called "Coolant Temperature Sensor: Description and Operation". Under "Purpose and Location" it reads "The coolant temperature sensor (B11/2)........" The second page of this sheet has the temp and ohm chart listing the proper readings. They are exactly as you described. If you remember the A/C TDCs I posted, I had an E0 43 - A/C system coolant temperature sensor (B10/8), open or short circuit ** error. I asked the inde to check this out. (I faxed them a copy of the TDCs, so I know they had B10/8 in black and white). What they tested was, apparently, the ECT sensor (B11/2), not the CTS (B10/8). I looked at the title of the ALLDATA sheet, saw Coolant Temperature Sensor (CTS?) and thought they had tested the right one. Sounds as if both may be bad. My gut tells me that neither of these could be very costly, so I think I should probably just replace them both and have some peice of mind.
I'm going back to the inde tomorrow afternoon to get this straight. You have been a lifesave Jim!
Hope my ignorance hasn't put anyone else on the wrong track with their problem!
