First this truck has a Nissan (now GCT) K21 Engine (not a Mazda 3.0) from the factory. Yes there was a problem with crank/cam sensors. A Parts & Service News was published in May 2013 (FT13004). The New Crank Sensor is 23731-6N21A & New Cam Sensor is 23731-6J90C. Its important to replace them as a set with the new ones.
