Does anyone know where I can find a wiring diagram or schematic for a 1998 to 2005 Dodge Caravan 3.3 Motor
I'm in hopes someone out there can help me find one. I've got a fault code of P1193 intake air temperature sensor voltage high. With the scan tool connected I'm showing an inlet temp. sensor value of 143 degrees with an outside temperature of roughly 45 degrees I know there's going to be a slight variation but not that much. At the I.A.T. sensor pigtail I've confirmed a good adequate ground but am not showing the 5 volt reference voltage with a known good meter. If I could come up with a diagram I would be able to confirm either a broken or bad wire between the computer and sensor or a bad ECM/PCM. I'm in hopes the years I've listed the manufacturer didn't make any changes. Can anyone HELP ?

Free wiring diagrams there for every make and model. Click on TSB's and Wiring Diagrams, agree to end user license agreement, then next page-click on wiring diagrams and enter vehicle information in the drop down boxes. The diagram you seek will be found under "Engine" system, and subsystem, probably "fuel controls". That one usually shows all of the engine sensors.
Hope it helps.
