Pilot Report: "EEC Inop" switch-light illuminated on overhead panel.

A review of the EEC Monitor unit showed two related failures.
  
  
 
  
  
 
  
  
The "T2" sensor displayed on box is really the "T12" sensor listed in the schematic and wiring manuals. The T12 sensor is located at the 7 O'Clock position in the engine inlet. 
  
  
 
  
  
We measured an open circuit from the EEC. (Note that the wiring to the sensor uses two sets of signal wires in parallel.)
  
  
 
  
  
A new sensor showed around 218 ohms resistance.
