When your 2024 Kia Sorento displays the P0305 code, the diagnostic significance depends on which engine is installed. The 2024 Sorento offers both four-cylinder and V6 options. P0305 is valid on the 3.3L V6 models but anomalous on four-cylinder configurations including the turbo and hybrid variants.
2024 Sorento Engine Options
The 2024 Sorento offers the 2.5L I-4 (191 hp), 2.5L Turbo I-4 (281 hp), 1.6L Turbo Hybrid (227 hp), and 3.3L Lambda II V6 (290 hp). Only the V6 has cylinder 5—four-cylinder variants do not.
If You Have the V6
On the 3.3L V6, cylinder 5 is located on the rear bank (toward the firewall) in the center position. Common causes include spark plug wear, ignition coil failure, intake manifold gasket issues, and fuel injector problems.
If You Have a Four-Cylinder
If your Sorento has the 2.5L, 2.5L Turbo, or hybrid powertrain, P0305 is anomalous since these engines have only cylinders 1-4. In this case, investigate diagnostic system issues rather than engine problems.
Diagnostic Approach
First, verify which engine is installed. On V6 models, proceed with standard cylinder 5 misfire diagnosis. On four-cylinder models, check for ECM issues, battery condition, and scan tool compatibility.
