My truck was in the dealer for a 66A recall on the crankshaft positioning sensor. The recall states the magnetic material attached to the tone wheel if lost the engine loses its ability to synchronize injector pulse and cam timing. The fix was a PCM reprogram to maintain engine operation if signal is lost. There is a prior recall W68 which address the tone ring for replacement on 2014-2016 model code DS W68 states loss of crankshaft position. the fix under this recall is to replace tone wheel and crank shaft positioning sensor. Because they could lose magnetic material on the tone wheel causing loss of signal from the crankshaft positioning sensor to the PCM. my truck loss power and showed throttle positioning sensor fault and engine light came on . i brought my vehicle into the dealer they diagnosed code po336-00 crankshaft positioning sensor performance. on further inspection found tone wheel has chunk of material missing causing code. they replaced tone wheel as instructed by W68 recall so why is my truck not covered under this recall for the exact same problem.
