Code P0401/97 F150 problem solved by cleaning the vacuum port in the throttle body/intake manifold. After 20 minutes of driving, the check engine light came on again, this time with code P0420. I did a little research online and found that the EPS4 EGR pressure feedback sensor can also cause this error. Replaced sensor, engine light went out by itself. So far so good, mileage 500 km. Thank you OEM for the exact replacement and fast shipping.
