P0171 Kia

Fix a P0171 code on a Kia

A P0171 Kia code is usually a sign of a bad MAF sensor. BUT, before you run to the auto parts store to buy a new one, check the air duct that runs from the air filter box to the throttle body. This duct is made from a woven fabric that can degrade and separate. Once that happens the fabric restricts airflow and the computer can set the following trouble codes

P0171 – Fuel system lean,bank 1
P0174- Fuel system lean, bank 2

The air duct must be replaced if it’s disintegrating. Do not try to repair it. Get a new one from the dealer.
