HI there,

The codes P0171 and P0174 are for a lean fuel mixture. This can be the result of a faulty fuel pump or mass air flow sensor.

P1111 is for a fault in the intake air temp sensor circuit. This is usually part of the mass air flow sensor and will cause the other codes.

As long as the car is running ok, you can drive it
