nope! mine has the pdc sensors installed (just did them!!) and while the plug is a two pin plug, it doesn not fit! similar size, but there are grooves in the end that do not allow a PDC sensor to fit in! (or a temp level or temp sensor for that matter!
Guess i will stroll out to the Dealership and see if they have any insight!
