This today from OASIS: Jun 05 2014 5010 -2013-2014 C-MAX, MKZ Hybrid, and Fusion with 2.0L ATK or 2.5L engine – DTC P0340 or P0344 - Cam Position Sensor Some 2013-2014 C-MAX, MKZ Hybrid, and Fusion vehicles equipped with 2.0L ATK or 2.5L engines may experience a concern with the Camshaft Position Sensor resulting in DTC P0340 and/or P0344. If the Pinpoint Test results in replacing the sensor, verify the build date of the new part is on or after October 3, 2013. Older parts could result in the vehicle returning with the same DTCs. The build date is a 4 digit code located on the side of the sensor when holding it with the electrical connector at the 3:00 position. The first two digits of the build date are the day in the month (e.g., 1-31). The third digit is the month (e.g., 1-9 = Jan-Sept, O=Oct, N=Nov, D=Dec). And the last digit is the year (e.g., 3=2013, 4=2014). For example, Oct 3, 2013 = 03O3, Dec 13, 2013 = 13D3, and Jan 1, 2014 = 0114.
