When your 2022 Ram 2500 displays diagnostic trouble code P0306, the engine control module has detected misfires in cylinder 6. The 2022 Ram 2500 offers the HEMI V8 and Cummins inline-6 diesel, both with six or more cylinders, making P0306 a valid diagnostic code.
2022 Ram 2500 Engine Options
The 2022 Ram 2500 offers the 6.4-liter HEMI V8 producing 410 horsepower and the legendary 6.7-liter Cummins turbo-diesel inline-6 producing 370 horsepower and 850 lb-ft of torque. Both engines can legitimately trigger P0306.
Engine-Specific Considerations
The HEMI V8 positions cylinder 6 on the passenger bank. The Cummins inline-6 positions cylinder 6 at the rear of the engine. Diesel misfires have different characteristics and causes than gasoline engine misfires.
Gasoline vs Diesel P0306
On the HEMI, typical ignition causes apply. On the Cummins diesel, there are no spark plugs. Instead, injector problems, glow plug issues, low compression, or fuel delivery problems cause misfires.
