A P0304 code appearing in your 2022 Nissan Rogue requires special consideration because this crossover uses a three-cylinder engine. Since P0304 specifically references cylinder 4 misfire, and the Rogue's engine has only three cylinders, this situation indicates potential diagnostic system issues rather than a traditional misfire problem.
Understanding P0304 in the 2022 Rogue
The 2022 Rogue features Nissan's 1.5L VC-Turbo three-cylinder engine with variable compression technology. This innovative powerplant numbers its cylinders 1, 2, and 3—no fourth cylinder exists. A P0304 code on this vehicle represents an anomaly requiring investigation into diagnostic integrity rather than cylinder 4 troubleshooting.
Code Verification Process
Use different OBD-II scanners to verify the code's presence. A single tool might display erroneous information from communication errors or data interpretation issues. Confirm vehicle identification and ensure no data crossover from previous scan sessions or nearby vehicles exists.
Addressing Actual Symptoms
If your Rogue exhibits misfire symptoms—rough running, hesitation, power loss—focus diagnosis on valid three-cylinder codes. P0301, P0302, and P0303 indicate misfires in cylinders that actually exist. Apply standard VC-Turbo diagnostics including spark plug inspection, ignition coil testing, and fuel injector evaluation.
Next Steps
Clear the questionable code and monitor for return. Investigate any actual drivability concerns using appropriate diagnostics. Dealer evaluation may be warranted if P0304 persistently stores without logical explanation, as ECM software or network issues could cause inappropriate code generation.
