In a Dodge Ram 1500, if you see Code P0302 on the Powertrain Computer, it means the system noticed over a 2 percent difference in RPM when comparing the firing of at least two cylinders in the correct order. The misfire could be due to issues with the ignition system, fuel system, or internal engine components. Often, worn spark plugs, spark plug wires, or a faulty ignition coil can trigger P0302. To address this, replacing the spark plugs and wires is a good starting point as they are usually the main culprits for this error code.
The error code P0302 on a Dodge Ram 1500 indicates a misfire has been detected in cylinder number 2.
