2010 Dodge Avenger Check Engine Light Flashing
A flashing MIL on a 2010 Avenger usually indicates an active misfire that can damage the catalytic converter. Follow these steps:
- Scan for DTCs, capture freeze-frame data, and note fuel trims.
- Swap ignition coils/plugs to identify faulty components; inspect injector pulse and fuel pressure.
- Check for vacuum leaks and verify compression to rule out mechanical issues.
- Repair the fault, clear the MIL with a scan tool, and complete a drive cycle to confirm the fix.
Additional procedures can be found in the Avenger CEL guide.
