1999 Ford E-Series Van V8 Two Wheel Drive Automatic 88,000 miles
Autotap scan tool indicates IAT to be 217F to 247F.
New MAF/IAT installed, same.
Wiring checks out okay from MAF/IAT module to computer connector.
Voltage output from IAT is about 2.5 volts.
No codes, just that MIL will NEVER run to completion.
Computer detects open IAT when I open the circuit.
IAT signal lead reads about 3.3 volts with circuit open.
have the same problem?
