Yeah, the same thing happened to me as I looked at my car today. The cable rides right under the camshaft water pump pully and rubs it till it breaks. Bad design by whoever designed it. I chacked with my local ford dealer and you cannot buy the cable by itself you have to buy the whole irmc box and they will never just offer the cable because there is no way to exchange it in the irmc box. that sucks! The box cost 131.00, so I told him to just keep it for now and I went home and removed the secondaries. I still get the CEL but my car runs alot better now.
Good luck
