1999 Ford Expedition Question: where can i find the pcm and where is the ect sensor
Answer #1patrick mannion from Greg Solow's Engine Room, September 21, 2009, 21:31Master
The electronic coolant temperature sensor is in the cylinder head on the driver's side in toward the center of the valley front of the engine. $30 switch .6 hour to replace.
I am sorry I don't know where the PCM is.
