Replaced all spark plugs and 6 coil packs this is a v10 6.8 liter engine also replaced 2 speed sensors what else could cause this

Answer 1

Hi there,

If there is a problem with the signal plate inside the tail shaft of the transmission it can cause this. Also, ohm the wiring from the TCM to the sensor and make sure it has continuity. If the wire is broken there won't be signal and the code will continue to show up.
