The P0302 diagnostic code on your 2024 Jeep Cherokee indicates cylinder 2 is experiencing misfires detected by the engine control module. Note that Cherokee production was discontinued in 2023, so if you have a 2024 model, it may be leftover inventory or a different market specification. This guide covers the Cherokee's available powertrains.
Cherokee Engine Options
The Cherokee offered the 2.4L Tigershark four-cylinder, 3.2L Pentastar V6, and 2.0L turbocharged four-cylinder. Cylinder 2 location varies: second from front on inline-4 engines, rear bank on the V6. Each engine has specific diagnostic considerations.
2.4L Tigershark Considerations
The naturally aspirated 2.4L uses multi-port injection. Common misfire causes include ignition coil failure, spark plug wear, fuel injector problems, and vacuum leaks. This straightforward engine responds well to standard diagnostics.
3.2L V6 Specifics
The Pentastar V6 provides 271 horsepower with port injection. Ignition and fuel system issues are primary misfire causes. Cylinder 2 is on the rear bank, requiring additional effort to access.
2.0L Turbo
The turbocharged four-cylinder adds boost variables and direct injection carbon potential. Boost pressure irregularities can cause misfires. Higher cylinder pressures stress ignition components.
Diagnostic and Repair Strategy
Identify your engine type. Scan for all codes including boost codes on turbo models. Inspect ignition components. Test fuel delivery. Standard maintenance often resolves misfire conditions.
