2022 Dodge Charger Check Engine Light in Millbury, MA

It means the OBD-II system stored a diagnostic trouble code (DTC) after detecting a fault.

On a 6.4L V8 2022 Dodge Charger, the issue can range from minor (loose gas cap/EVAP leak) to serious (misfire). The code identifies the affected system so our Millbury team can isolate the true cause, not just the symptom. Schedule a quick code check and plan your next step with a written estimate.

• Common examples: P0456 (small EVAP leak), P0304 (misfire, cylinder 4), P0128 (coolant temp below thermostat)
• A steady light signals non-urgent faults; flashing indicates a severe misfire

The five most common causes are O2 sensor faults, EVAP leaks, engine misfires, catalytic converter efficiency issues, and MAF sensor problems.

For the 6.4L V8 HEMI, worn spark plugs or coils can trigger misfire codes; a loose or failing gas cap often sets EVAP codes. New England temperature swings can exacerbate EVAP and cold-start concerns. Our Millbury Service Center confirms the root cause before recommending repairs.

• Watch for rough idle, hesitation, or sulfur smell (possible catalyst issue)
• Drop in MPG may indicate O2/MAF sensor performance concerns
• Start with a factory scan and inspection: book now

A steady light means drive cautiously to service; a flashing light signals a severe misfire—stop driving to avoid catalytic converter damage.

If the light is steady on your 2022 Dodge Charger, reduce load and head to our Millbury facility for diagnosis. A flashing light can overheat and melt the catalyst, leading to expensive repairs. When in doubt, arrange a tow and we’ll perform a factory-level scan.

• Check your gas cap; a loose cap can trigger EVAP codes
• Avoid hard acceleration if the light is on
• Schedule an appointment for a prompt inspection

Parts stores read generic codes; our dealership performs full diagnostics with factory scan tools, OEM data, and isolation testing to find the exact cause.

A code alone doesn’t confirm the failed part—multiple faults can set the same DTC. Our OEM-trained technicians access manufacturer-specific data, run pinpoint tests, and verify the fix on the road. You’ll receive a clear, written estimate before any repair is started.

• Factory scan capability across engine, transmission, ABS, and more
• Smoke/pressure testing for EVAP and vacuum leaks as needed
• Documentation for Massachusetts emissions and service records

No—Massachusetts OBD emissions tests fail vehicles with active DTCs or unset readiness monitors after a reset.

Clearing codes erases readiness data; monitors must complete drive cycles before inspection. If your 2022 Dodge Charger has an EVAP or catalyst issue, it will likely fail until the fault is fixed and monitors are ready. We can pre-check readiness status and advise next steps.

• Drive cycles may take multiple trips to set all monitors
• EVAP readiness often sets last, especially in cooler weather
• Get a readiness check: schedule service

Most diagnostics are completed within one business day with an appointment.

The initial OBD-II scan and freeze-frame review are quick; time varies if further isolation tests are needed (for example, smoke testing an EVAP leak or verifying an intermittent misfire on the 6.4L V8). Plan to leave the vehicle if symptoms are intermittent so our technicians can reproduce the condition.

• Book online: schedule appointment
• Bring any prior repair receipts and note conditions when the light set
• Check current service specials before you arrive

Your visit starts with a factory scan of your 2022 Dodge Charger to retrieve DTCs and freeze-frame data. Next, an OEM-trained technician verifies symptoms and performs targeted inspections—visual checks for wiring and vacuum lines, smoke/pressure testing for EVAP leaks, and pinpoint electrical testing where required. We review applicable service bulletins and confirm the fault path before recommending repairs. You receive a written estimate and our findings so you can make an informed decision. Because the 6.4L V8 can set misfire, EVAP, and sensor-related codes, verification testing protects you from replacing parts unnecessarily. Have a light on today?

Our Central Massachusetts location makes diagnosis straightforward for drivers across Worcester County—including Worcester, Auburn, Grafton, Shrewsbury, Sutton, and Oxford. The difference is depth: a generic OBD-II reader can display codes, while our factory scan tools access manufacturer-specific data streams, readiness monitors, and module reports across the vehicle. Seasonal factors matter here; cold starts and temperature swings can surface EVAP and misfire concerns that require proper verification. Visit us at 2 Latti Farm Road (off Route 20), Millbury, MA 01527. Have questions about your 2022 Dodge Charger? Book online to secure an appointment or stop by our Service Center for guidance.

Misfire codes P0300/P0301–P0308 often indicate ignition or fueling issues; on a 6.4L V8, continuing to drive with a misfire can overheat and damage the catalytic converters. Catalyst efficiency codes P0420/P0430 may stem from prolonged misfires or sensor faults; ignoring them risks higher repair costs and failed emissions. EVAP system codes P0455/P0456 frequently result from a loose or failing gas cap or small leaks—smoke testing confirms the source. Airflow/fuel codes like P0101 (MAF performance) and O2 sensor voltage/performance codes can degrade power and MPG.
