Well, My 08 FEH now has 25,000 miles. Recently, the Wrench light has been coming on. Until I got my owners manual out, I thought this was a service engine soon light. I see that it,s a Throttle/Powertrain Fault light. I have a scangauge II and it shows no codes. Does anyone know if this is an OBD II indication or is it a seperate system? Also, anyone else have this indication, and if so, What was the problem. The light comes on only sometimes and always resets on restart.
