Dodge Ram Check Engine Light Flashing 10 Times
A flashing MIL that pulses repeatedly (often around 10 times) signals a severe misfire or fuel control fault. Immediate steps:
- Reduce throttle and avoid heavy load to protect the catalytic converters.
- Scan for misfire codes (P0300–P0308) and note freeze-frame data.
- Swap ignition coils/plugs, check fuel pressure, inspect injectors and vacuum leaks.
- Repair the root cause, then clear the MIL with a scan tool and confirm trims return to normal.
Do not ignore a flashing MIL—it indicates damage is occurring.
Refer to the Ram diagnostic guide for detailed misfire workflows.
