A P0302 code on your 2022 Nissan Pathfinder indicates that the powertrain control module has detected misfires in cylinder 2. The fifth-generation Pathfinder introduced for 2022 continues with the proven 3.5L VQ35DD V6 engine producing 284 horsepower. This direct-injection V6 pairs with a new 9-speed automatic transmission for improved efficiency.
Redesigned Platform Considerations
While the 2022 Pathfinder rides on a new platform, the VQ35DD engine remains familiar. Cylinder 2 is positioned on the rear bank of the 60-degree V6. The direct injection system and variable valve timing are unchanged, meaning diagnostic approaches remain consistent with previous VQ35DD applications.
Common Misfire Sources
Even on newer vehicles, component failures can occur. Ignition coil defects, spark plug issues, and fuel injector malfunctions are possible. Direct injection carbon buildup typically develops over time but manufacturing variations can accelerate deposits. Software calibration issues are also possible on first-year redesigns.
Symptom Identification
The smooth V6 becomes noticeably rough when cylinder 2 misfires. Idle quality suffers, hesitation occurs during acceleration, and the check engine light illuminates. The new 9-speed transmission may exhibit unusual shift behavior trying to compensate for reduced engine output.
Diagnostic Steps
Comprehensive scanning should check for TSBs or software updates affecting the 2022 model. Inspect ignition components on cylinder 2 for defects. Monitor fuel system operation and injector performance. Check for vacuum leaks or intake system issues. Given the new model year, dealer diagnosis may be beneficial for warranty and technical information access.
Repair and Warranty
Most repairs on a 2022 vehicle should be warranty-covered. Ignition component replacement, fuel system service, and software updates are typically performed at no cost under the bumper-to-bumper or powertrain warranty. Document symptoms thoroughly for the service advisor.
