Where is the eec relay located on a 2002 Lincoln navigate
What do you think a EEC relay is ?
Electronic
Engine
Control
It is the relay that sends power to the PCM (computer). Try swapping the relay with another one in the fuse box and go from there.
But on your vehicle it's not called that , it's PCM power relay . It's located in the under hood fuse / relay box .
right side big square ,second row down. PCM power relay .
Rear suspension will deflate but why won't it inflate?
That could work , You mite be able to test the sensor in question with ohm meter . Test the front one an see what the resistance is ,then check the back one. I don't know what it should be with out looking it up in the service info . You could also check to see if the sensor is getting power from the control module , an see if there is a return input to the module .
There are a few DTC'S this able to set !

2002 Lincoln navigator won't start the anti theft
Disconnect the battery cable and leave disconnected for 5 to 10 minutes. Reconnect cable and see if this resets the security system. If light is not flashing, then it should have reset. If when trying to start and the theft light comes on again, have your key checked to see if it has lost its code. If you have a second key, try using it. If this does not work, you may have to have the system flashed at the dealership.

I had a similar problem on my 2002 nav and it was a broken vacuum line on the top of the engine under plastic cover that has the engine size on it
