If your 2022 Kia Sportage is displaying a P0305 code indicating a cylinder 5 misfire, this code requires diagnostic investigation. The 2022 Sportage (final year of the fourth generation) used only a four-cylinder engine: the 2.4L naturally aspirated I-4. With only four cylinders, P0305 is technically anomalous.
2022 Sportage Powertrain
The fourth-generation 2022 Sportage used the 2.4L Theta II I-4 producing 181 horsepower. This was the only engine available. The V6 option from earlier generations had been discontinued. All 2022 Sportages have exactly four cylinders.
Understanding the Anomalous Code
Since the 2022 Sportage has exactly four cylinders numbered 1-4, a P0305 code cannot represent an actual cylinder 5 misfire. This is an erroneous diagnostic code.
Possible Causes
ECM software issues can store invalid codes. Scan tool communication errors may misread data. Low battery voltage affects ECM reliability. Aftermarket diagnostic tools may have compatibility issues with Kia electronics.
Diagnostic Steps
Use a Kia-compatible scan tool to verify codes. Test battery condition. If actual misfire symptoms exist, diagnose cylinders 1-4. Clear the erroneous code and monitor.
