A P0302 code on your 2022 Jeep Compass indicates the engine control module has detected misfires in cylinder 2. The second-generation Compass is powered by the 2.4L Tigershark four-cylinder producing 177 horsepower. This naturally aspirated engine with multi-port injection provides reliable, efficient operation.
Tigershark Engine Overview
The 2.4L Tigershark is an inline-4 with dual overhead cams and multi-port fuel injection. Cylinder 2 is positioned second from the timing chain end. Unlike direct-injection engines, port injection sprays fuel onto intake valves, reducing carbon buildup concerns. The straightforward design facilitates diagnosis and repair.
Common Misfire Causes
The Tigershark experiences standard gasoline engine issues: ignition coil failure, spark plug wear, fuel injector clogging, and vacuum leaks. These are well-documented problems with established diagnostic techniques. The simpler port-injection design has fewer potential failure points.
Symptom Recognition
The compact Compass displays pronounced four-cylinder misfire symptoms. Rough idle is very noticeable in the small SUV cabin. Vibration, hesitation during acceleration, and reduced fuel economy accompany the check engine light illumination.
Diagnostic Process
Scan for all codes and freeze frame data. Inspect cylinder 2 spark plug for condition. Test ignition coil functionality. Check fuel injector operation. Verify no vacuum leaks exist. Compression testing confirms cylinder health.
Repair Solutions
Replace spark plugs with quality iridium units at recommended intervals. Replace faulty ignition coils. Service fuel injectors as needed. Given the newer model year, warranty coverage should apply to defect-related repairs.
