4. Kia EV6 P0134 FAQs
What causes code P0134 to trigger on a Kia EV6?
On the Kia EV6 (Single RWD (229HP) / Dual AWD (320HP) / GT 577HP / 77.4 kWh battery), P0134 is most frequently caused by Dead upstream Oxygen (O2) / Air-Fuel sensor or Blown O2 sensor heater fuse or broken power wire.
Where is the OBD-II port located on my Kia EV6?
On the Kia EV6, the 16-pin DLC diagnostic connector is located Driver side lower dash bezel interface. 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 EV6 with code P0134?
Yes, for limited driving. Vehicle will run in open-loop fail-safe mode with reduced fuel economy. Given that P0134 carries a High severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
