The most common cause of the DTC (Diagnostic Trouble Code) PO320 is either a defective CKP (Crankshaft Position) sensor or poor connection. Inspect the Crankshaft Position (CKP) sensor circuits and harness for a possible chafe on ground.Wiggle test the CKP sensor circuits with the engine idling to see if tapping or wiggling on the harness will result in a misfire or stall condition.

Take the numbers from the sticker, the VIN code and proof of ownership to a dealer to get the code. They won't do this over the phone. I hope this helps, Take care

THIS IS A COMMON CODE.. THIS IS A PRESSURE SELENOID LOCATED INSIDE THE TRANSMISSION.... SOMETIMES CALLED A SHIFT SELENOID... THERE IS A FIRST TO SECOND SHIFT SELENOID AND A SECOND TO THIRD AND A THIRD TO OVERDRIVE... THE SHORT CIRCUIT CODE CAN BE TWO THINGS.. FIRST A BAD SPOT IN WIRING HARNESS CAUSING SHORT CONDITION.. DOUBTFULL... OTHER CONDITION IS THE SELENOID ITS SELF COULD BE GOING BAD DRAWING MORE CURRENT THAN NORMAL. THIS WILL REGISTER THIS CODE....YOU HAVE TO REMOVE THE TRANSMISSION PAN TO EXSPOSE THE VALVE BODY.. THERE YOU WILL SEE SEVERAL SHIFT SELENOIDS...WHEN YOU PURCHASE THE REPLACEMENT IT WILL GIVE YOU A GOOD IDEA WHAT TO LOOK FOR....THEY JUST PLUG IN AND 1 OR 2 SCREWS HOLD THEM IN.... LET ME KNOW IF MORE HELP NEEDED

Common fault on FORD

Usually due to a poor connection in the YELLOW PLASTIC CONNECTOR underneath the passenger seat.

Just push it together properly and it should clear the AirBag fault
