System too lean was created by Dimitris

Hello everyone
I got a Jimmy 2005, m13 engine, and the engine light is on The diagnostic show me error "system too lean" . Does anyone have an idea what to look for?

Possibly a Vacuum leak assuming the sensors are ok.
The actual code number if you have it may narrow down where the problem lies.

Does this engine has both MAP and MAF sensors?
