Just had a issue with this same problem 2015 ram eco diesel 69,000 miles and went to pass a semi going slow on in traffic, pushed the pedal down and made a noise then stop running and will not start, had to be towed into the dealer after the tear down a price of the magnet is missing parts are on backorder, the dealer got them from a dealer that had them in stock luckily It was under warranty threw emissions update and it is still in the shop they fount a major oil leak around the turbo you would not think this many problem for this meany miles and I don’t toll anything. This is the second sensor that went out the first was a boost sensor.Had a friend loose the Crank Sensor just like I did. His was under warranty and they replaced the pump, injectors and one other thing. Just a way to milk the warranty for more money.
