The P0304 code in your 2024 Jeep Cherokee indicates the engine control module has detected persistent misfires in cylinder 4. The compact SUV's available engine options require understanding your specific configuration for targeted diagnosis of this combustion problem.
Understanding P0304 in the 2024 Cherokee
The 2024 Cherokee offers the 2.4L Tigershark four-cylinder as standard with the 3.2L Pentastar V6 available in higher trims. Cylinder 4 location varies—on the inline-four it's the rearmost position, on the V6 it's on the rear bank. Each configuration presents different access and diagnostic considerations.
Engine-Specific Misfire Causes
The 2.4L four-cylinder faces standard ignition wear patterns. The 3.2L V6 provides more power with additional cylinders to manage. Both engines use port fuel injection rather than direct injection, avoiding carbon buildup concerns on intake valves. Standard ignition component wear—spark plugs and coils—represents the most common cause.
Diagnostic Methodology
Identify your engine type—2.4L I4 or 3.2L V6. Retrieve all codes and analyze freeze frame data. Locate cylinder 4 appropriate to your configuration. Test ignition coil output and spark plug condition. Verify fuel injector operation through appropriate testing methods.
Repair Solutions
Install Jeep-specified spark plugs for your engine type. Replace degraded ignition coils. Address fuel injector concerns through cleaning or replacement. The Cherokee's straightforward port injection simplifies fuel system diagnosis.
