4. Kia Sportage P0452 FAQs

What causes code P0452 to trigger on a Kia Sportage?

On the Kia Sportage (2.5L 4-Cyl (187HP) / 1.6L Turbo Hybrid (227HP) / PHEV (261HP)), P0452 is most frequently caused by Faulty Fuel Tank Pressure (FTP) sensor or Short to ground in sensor signal wire.

Where is the OBD-II port located on my Kia Sportage?

On the Kia Sportage, the 16-pin DLC diagnostic connector is located Under driver steering column. 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 Sportage with code P0452?

Yes. Fuel tank pressure sensor shorted to ground. Given that P0452 carries a Low severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
