Where is the crank sensor for a 2003 expedition 5.4L. I get the PO320 code, speed input circuit malfunction. Motor just dies when traveling at high speeds. Key must be turned off before restart is successful. Does anyone know where the crank sensor is? I'll try that.

 

Passenger side right behind the crank pulley

That code has about 20 pages worth of tests to run to pinpoint the problem as well
