The 2024 Ram 2500 delivers exceptional heavy-duty performance with its 6.4L HEMI V8 gasoline engine. When a P0304 code appears indicating a cylinder 4 misfire, addressing it promptly ensures your truck maintains the power and reliability needed for demanding work applications.
Understanding P0304 in Your Ram 2500
The 6.4L HEMI in the 2500 is a dedicated heavy-duty engine without the Multi-Displacement System found in half-ton trucks. Cylinder 4 is positioned on the right (passenger) bank of the V8. The powertrain control module monitors each cylinder's contribution through crankshaft position analysis to detect misfires accurately.
New Vehicle Considerations
Misfires on new 2024 models are uncommon and typically indicate manufacturing defects covered under warranty. The heavy-duty 6.4L HEMI is built for reliability, and component failures on new vehicles are exceptions rather than the norm. Software calibration issues are also possible on first-year updates.
Diagnostic Steps
Access the cylinder 4 ignition coil on the right bank of the engine. Inspect for any shipping damage or manufacturing defects. The coil-on-plug design allows isolation testing. Check spark plug installation and condition. Verify all software updates have been applied.
Resolution Path
As a 2024 model, warranty coverage applies to component failures. Have your Ram dealer diagnose using their specialized equipment and access to current technical service bulletins. If diagnosing independently, test ignition coil output and verify spark plug condition.
