P0174 KIA -

Question

I have 2004 KIA Sorento and it has P0171 and P0174 codes. What can I do to fix, identify parts, and where to look?

Answer 1

You need to try to diagnose the problem first. The codes mean that the engine mixture is running too lean, its possible that you have an air leak, bad oxygen sensor or clogged injectors.

See "Possible Causes" on the code page:
