The 2024 Dodge Hornet delivers compact crossover performance with choice of turbocharged powertrains. When a P0304 code appears indicating a cylinder 4 misfire, understanding your specific configuration helps target effective diagnosis.
Understanding P0304 in Your Hornet
The Hornet offers a 2.0L turbocharged four-cylinder (GT) or 1.3L turbo plug-in hybrid (R/T). For the 2.0L GT, cylinder 4 is at the rear of the inline-4. For the PHEV, the smaller turbo engine's cylinder 4 is similarly positioned. Both use individual coil-on-plug ignition.
Powertrain-Specific Factors
The 2.0L turbo operates under high combustion pressures demanding quality ignition components. The 1.3L PHEV combines internal combustion with electric assist, adding complexity to diagnosis. Both engines use direct injection which can contribute to carbon buildup.
Diagnostic Steps
Identify your powertrain configuration. Access the cylinder 4 ignition coil. Inspect spark plug condition. On turbo models, check for boost leaks. On PHEV, verify hybrid system isn't masking combustion issues.
Resolution Path
Warranty coverage applies to 2024 models. Have your Dodge dealer diagnose using factory equipment designed for these European-derived powertrains. Component failures should be covered.
