A P0302 code on your 2022 Mazda CX-50 indicates the engine control module has detected misfires in cylinder 2. The CX-50, introduced for 2022, offers the Skyactiv-G 2.5L naturally aspirated or Skyactiv-G 2.5T turbocharged four-cylinder. This adventure-oriented SUV has specific diagnostic considerations.
CX-50 First Year Model
As a 2022 introduction, the CX-50 brought Mazda's proven Skyactiv technology to a more rugged platform. The 2.5L produces 187 horsepower while the turbo delivers up to 256 horsepower. Both inline-4 engines position cylinder 2 second from the timing end.
First-Year Considerations
As a first-year model, check for applicable TSBs and software updates. Component defects rather than wear are more likely causes. Manufacturing refinements may have been implemented during production.
Common Misfire Causes
Direct injection can develop carbon over time. Ignition coil and spark plug issues are primary causes. The high-compression naturally aspirated engine is sensitive to deposits. Turbo models add boost variables.
Symptom Recognition
The compact SUV displays rough idle, vibration, and hesitation with misfires. Four-cylinder engines show pronounced symptoms. Check engine light accompanies the condition.
Diagnostic and Repair Approach
Identify engine type. Check for TSBs. Scan for all codes. Inspect ignition components. Test fuel system. Verify boost on turbo models.
