DENSO Auto Parts Oxygen Sensor P/N:234-4840
DENSO Auto Parts 234-4166 right oxygen sensor for the 2003-2006 Kia Sorento V6 3.5L and other vehicles reports the oxygen level in the exhaust to the engine computer. It is a direct-fit replacement made and tested to OE standards.
A check engine light, poorer fuel economy or a failed emissions test can mean an oxygen sensor is wearing out. Those signs alone do not prove the sensor is at fault, since an exhaust leak is another common cause.
This sensor fits the 2003-2006 Kia Sorento V6 3.5L and the 2003-2006 Hyundai Santa Fe V6 3.5L.
