The P0302 diagnostic code on your 2024 Mazda CX-90 indicates cylinder 2 is experiencing misfires detected by the engine control module. The new CX-90 offers multiple powertrains: the Skyactiv-G 3.3T turbo inline-6, 3.3T mild hybrid, and plug-in hybrid options. Each configuration has specific diagnostic considerations.
CX-90 Powertrain Innovation
The CX-90 introduces Mazda's new 3.3L turbocharged inline-6 engine. The base turbo produces 280 horsepower. The mild hybrid version adds e-Skyactiv assist for 340 horsepower. The PHEV combines a 2.5L engine with electric motors. Cylinder 2 location varies by configuration.
New Engine Considerations
The 3.3L turbo inline-6 is a new design for Mazda. As a first-year application, check for TSBs and software updates. Component defects rather than wear are more likely causes on new vehicles.
Potential Misfire Causes
Manufacturing variations in ignition coils or fuel injectors can cause misfires. The new inline-6 architecture may have early production refinements. PHEV has additional complexity from hybrid system coordination.
Symptom Recognition
The large SUV displays rough idle, vibration, and hesitation with misfires. Six-cylinder smoothness becomes disrupted. Check engine light accompanies the condition.
Warranty Coverage
Your 2024 CX-90 is fully covered under Mazda's warranty. Document symptoms and have dealer diagnosis using Mazda-specific equipment for proper coverage.
