When your 2024 Jeep Cherokee displays the P0305 code, the diagnostic significance depends on which engine is installed. The 2024 Cherokee offers both four-cylinder and V6 options. P0305 is valid on the 3.2L Pentastar V6 but anomalous on the 2.4L Tigershark four-cylinder.
2024 Cherokee Engine Options
The 2024 Cherokee offers the 2.4L Tigershark I-4 (180 hp) on base models and the 3.2L Pentastar V6 (271 hp) on higher trims. Only the V6 has a cylinder 5—the four-cylinder has cylinders 1-4 only.
V6 Diagnosis
On the 3.2L Pentastar V6, cylinder 5 is on the driver side bank toward the rear. Common causes include spark plug wear, ignition coil failure, intake manifold gasket issues, and fuel injector problems.
Four-Cylinder Models
If your Cherokee has the 2.4L Tigershark, P0305 is anomalous. Investigate diagnostic system errors, battery condition, and scan tool compatibility.
Diagnostic Approach
Verify which engine is installed. On V6 models, proceed with standard cylinder 5 misfire diagnosis. On four-cylinder models, check for ECM errors and clear the code.
