2008 Expediton Limited 4x4 59k miles. The rsc squiggle vehicle in message center has been staying on for awhile at random times. It happens at fast and slow speeds on dry roads, straight line, i do not think the system is activating I think its telling me a fault. Its at the Ford dealer and they say its a sensor in the steering wheel causing it, we rarely ever use the tilt function on the steering wheel. They are charging $230 parts and labor to fix it, I said go ahead, anyone else have this problem ? Thanks for all replies !!

 

Just got the Expedition from dealer. they replaced steering wheel rotation sensor and calibrated it. Sensor 9L1Z-3F818-A $36.00 and &176.00 labor. I asked for the old part and its all plastic and looks like one mounting ear was cracked not sure if that was from removal or like that from the factory. It looks to be u shaped and and a disc must travel inside the u. Thw disc must have slots in it, the u looks to have a led light on one side and detector on the other. It must count pulses as light passes through slots and is blocked where there are no slots. I'll give an updated in a week or so to see if problem is fixed.
