The 2022 Genesis GV70 delivers luxury compact SUV performance with powerful turbocharged engines. When your GV70 displays a P0304 code indicating a cylinder 4 misfire, understanding your engine configuration helps target accurate diagnosis.
Understanding P0304 in the GV70
The 2022 GV70 offers the 2.5L turbocharged four-cylinder or 3.5L twin-turbocharged V6. For the four-cylinder, cylinder 4 is at the rear of the engine. For the V6, cylinder 4 is on the rear of the left bank. Both use individual coil-on-plug ignition.
Turbo Engine Considerations
Both GV70 engines are turbocharged, creating higher combustion pressures. This accelerates spark plug wear and demands quality ignition components. Direct injection can contribute to carbon buildup on intake valves over time.
Diagnostic Approach
Identify your engine and access cylinder 4 accordingly. Inspect spark plug condition. Check for boost leaks. Verify no vacuum leaks exist.
Resolution Process
Replace spark plugs with Genesis/Hyundai specifications. Test ignition coil output. Address any boost system issues.
