Default Code P0174
My 2001 Montero Sport's check engine light came on and the code reading was P0174, System too lean, Bank No. 2.

What exactly does that mean and how do I correct this?

Any help would be appreciated!!

Thanks.

Lean means the o2 sensor is reading too much oxygen. You could have a vacuum leak, bad o2 sensor,bad maf or clogged injectors..
