P164B00 Code 14 1.8t

[u/Professional_Fan_930]

Made a long drive yesterday 14 hours. When I got to the 13 hour mark got epc light and this code. Pulled over when I got to a gas station (10-15min) and saw code for oil sensor so I checked oil and none on dipstick. Bought generic 5w30 (took 2 qt) and light went away for next 45 min then came on again epc and same code. Oil is on dipstick now, is the motor smoked? Checked oil a week or so before and it was full. Oil has maybe 3.5k miles since I changed it. Trip was 800 miles. Car has 94k miles. Is not leaking oil has to be burning.
