A P0302 code on your 2022 Infiniti QX80 indicates that the engine control module has detected cylinder 2 misfires beyond acceptable parameters. This full-size luxury SUV features a powerful V8 requiring proper diagnostic attention.
2022 QX80 Powertrain
The 2022 Infiniti QX80 is powered by a 5.6L V8 engine producing 400 horsepower. This naturally aspirated eight-cylinder provides effortless power for this flagship luxury SUV.
V8 Engine Configuration
The VK-series 5.6L V8 features direct injection and Variable Valve Event and Lift (VVEL) technology. With eight cylinders, individual misfires are somewhat masked but still affect performance and refinement.
Cylinder 2 Location
In the V8 configuration, cylinder 2 is located on one bank. Bank-specific issues including fuel delivery or exhaust flow should be considered along with individual cylinder components.
Flagship Luxury Standards
The QX80 is Infiniti's flagship SUV, expected to provide supremely smooth V8 power. Any misfire disrupts this experience and warrants immediate attention.
High-Mileage Considerations
V8 engines may develop different issues at higher mileage including carbon buildup on intake valves due to direct injection, or wear in ignition components.
