code 174 on Suzuki grand vitara v-6 year 2002 120000 miles

Question

vitara run ok . no difference .the engine light stay on.

Answer 1

P0174 Fuel system too lean Bank 2

Vacuum leaks can cause this code condition, worn  sparkplugs can also cause this code condition. What you look for s vacuum leak especially the PCV valve and its PCV hose.

 On the Suzuki Vitara there a vacuum hose that goes to the EVAP canister this hose here tends to rot away and disconnect, this would be a good area to check , if it does leak t will cause just Bank 2 to go lean.
