If your 2022 Honda Accord is displaying a P0305 code, this requires careful investigation. The tenth-generation Accord (2018-2022) uses exclusively four-cylinder engines, meaning cylinder 5 does not physically exist in this vehicle.
Understanding P0305 in the 2022 Accord
The P0305 code indicates a misfire on cylinder 5. Since the 2022 Accord uses either the 1.5L turbo or 2.0L turbo four-cylinder—with only cylinders 1-4—this code represents a diagnostic anomaly.
No V6 in This Generation
The tenth-generation Accord discontinued the V6 engine option. All 2022 Accords are four-cylinder, making P0305 impossible under normal operation.
Diagnostic Approach
Verify the code with a quality scanner. Clear and monitor for return. If genuine misfire symptoms exist, expect P0301-P0304 codes for the actual cylinders.
Resolution Steps
Have a qualified technician investigate the diagnostic system. Check sensor operation and ECM function.
