Sedona EX V6-3.5L (2002)
Oxygen Sensor: Technical Service Bulletins
Engine Controls - Oxygen Sensor Codes
SOURCE: KIA Technician Times Volume 5 Issue 4, 2002
TITLE: Oxygen Sensor Codes
APPLIES TO: Sedona
SERVICE TIP:
To eliminate the possibility of false codes P0139 and P0159 (rear O2 sensor response time), the ECM logic for these codes has been revised. Should
you encounter one or both of these codes on an '02 Sedona with no other problems found, check the production date of the vehicle. If the vehicle was
built before 11/19/01 and the ECM has not been updated for cold start hesitation, reflash the ECM per Technical Service Bulletin Volume 2, Engine
005. The reflash includes the logic change for the O2 sensor related DTCs mentioned above. If the update has already been done, diagnose the codes
using the normal procedure in the Sedona Service Manual.
