p1131 code on 01 f150

We just had our truck in the shop two months ago to get the air intake manifold gasket replaced. Just last week we went over a bumpy railroad track and the service engine light came back on, oh shoot. When I went down to the autostore and used their scanning tool it came back with p1131 lack of h02s11, switches-sensor indicates lean.

The last code when we had this air intake gasket fixed was like p1171 & p1174 i believe.

What can I check for, please avoid too much jargon...
Thanks alot
