4. Kia K5 P0605 FAQs
What causes code P0605 to trigger on a Kia K5?
On the Kia K5 (2.5L 4-Cyl (191HP) / 2.5L Turbo GT (290HP) / 1.6L Turbo (180HP)), P0605 is most frequently caused by Corrupted ECM firmware or Failed internal ROM chip in ECM.
Where is the OBD-II port located on my Kia K5?
On the Kia K5, the 16-pin DLC diagnostic connector is located Driver lower dash left of center stack. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Kia K5 with code P0605?
No. ECM internal memory checksum failure. Given that P0605 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
