ETA Potentiometer Values

I have a friend who successfully resoldered the ETA wiring harness on a 500S. He had to do both ends since the canon plug end was not the 90 degree type. Now, he's still getting a code related to idle speed and he's thinking it's one of the two potentiometers inside the ETA.

Does anyone know what kind of resistance or voltage values you should get from an operable ETA or how to troubleshoot the ETA itself?

1993 400E, 256,000 miles (totaled)
1994 E420, 200,000+ miles
1995 E420, 201,000 miles
