Which coolant sensor sends signal to DME?

[Petebee]

We have two coolant sensors on the M42 cars. I believe the coolant sensor towards the front of the head (closer to the fan) sends the temperature signal to the temp gauge. I think the one towards the middle of the head (buried under the intake) sends the temperature signal to the DME.

Can someone confirm that I have this right? I plan to replace the DME sensor but want to make sure I get the correct part.

Thanks!

I think you have at turned around, as my CTS closest to the fan failed and i had CEL, no problems with the gauge. I replaced that CTS and have had no problems since.

Okay cool...what symptoms where you having? I am having overall crappy performance and tough restarts once engine is hot.
