2001 Other Ford Models Code P1260 Theft Detected - Engine Di

This code is unlikely to cause the engine to stop running once it is started and driving. It can cause a start and stall, but it should not cut the engine off while you are driving down the road.

So, I suspect the engine stalled and then it entered into a theft mode.

So, the way to get this code to clear is we need to disable the theft mode.

Also, we need to make sure there are no other codes. Normally this code is just an informational code that will tell you that there are others.

If not, we need to find out if there were any engine related codes that could explain the cut off.

If there are no other codes and this is the only one, then we need to simply reset the memory by disconnecting the battery and then retest the operation.

Please run through this info attached and let us know what you find.

Thanks
