The P0302 trouble code on your 2022 Kia Sorento indicates that cylinder 2 is experiencing misfires detected by the engine control module. The fourth-generation Sorento launched in 2021 offers multiple powertrains including the 2.5L Smartstream, 2.5L turbocharged, and 1.6L turbo hybrid options. Each engine configuration requires different diagnostic approaches.
Engine Options
The Sorento features inline-4 engines with cylinder 2 positioned second from the timing end. The base 2.5L uses multi-port injection for simplicity. The 2.5L turbo adds direct injection and forced induction. The hybrid pairs a 1.6L turbo GDI with electric motor assistance.
Port Injection 2.5L
The naturally aspirated 2.5L Smartstream avoids direct-injection carbon buildup. Common misfire causes include ignition coil failure, spark plug wear, and fuel injector problems. This engine responds well to standard diagnostic techniques.
Turbo and Hybrid Specifics
The 2.5L turbo and hybrid 1.6L turbo use direct injection susceptible to carbon accumulation over time. Boost system issues can affect combustion. The hybrid's intermittent engine operation creates different wear patterns than conventional vehicles.
Symptom Recognition
The mid-size Sorento displays noticeable four-cylinder misfire symptoms: rough idle, vibration, and hesitation. Hybrid models may mask symptoms during electric-only operation. Check engine light illumination accompanies the condition.
Repair Strategy
Identify your powertrain type. Scan for all codes including hybrid system codes. Inspect ignition components. Test fuel delivery appropriate to injection type. Turbo models require boost evaluation. Warranty coverage should apply to component defects.
