When your 2022 Kia Sorento displays the P0305 code, the diagnostic approach depends on your engine configuration. The fourth-generation 2022 Sorento offers multiple powertrains including four-cylinder and V6 options. P0305 is valid on the V6 but anomalous on four-cylinder configurations.
2022 Sorento Powertrain Options
The 2022 Sorento offers the 2.5L I-4 (191 hp), 2.5L Turbo I-4 (281 hp), 1.6L Turbo Hybrid (227 hp), 1.6L Turbo PHEV (261 hp), and 3.3L Lambda II V6 (290 hp). Only the V6 configuration has a cylinder 5.
V6 Diagnosis
If your 2022 Sorento has the 3.3L V6, cylinder 5 is on the rear bank in the center position. Common causes include spark plug wear, ignition coil failure, intake gasket issues, and fuel injector problems. Standard misfire diagnostic procedures apply.
Four-Cylinder Models
If you have the 2.5L, 2.5T, hybrid, or PHEV, P0305 is anomalous—these engines have only cylinders 1-4. Investigate ECM software issues, battery condition, and scan tool compatibility instead.
Diagnostic Steps
Confirm your engine configuration first. For V6 models, inspect cylinder 5 components. For four-cylinder models, check for diagnostic system errors and clear the erroneous code.
