2016 Dodge Charger Check Engine Light in Millbury, MA

It means the engine computer stored a Diagnostic Trouble Code (DTC) identifying an emissions or powertrain fault.

Your 2016 Dodge Charger uses OBD-II to flag issues ranging from a loose gas cap to misfires or sensor faults. A code like P0456 (small EVAP leak) or P0301 (cylinder 1 misfire) guides our next tests. In Millbury, our dealer tools read live data and freeze frames to confirm the cause, not just the symptom. If the light is on, schedule service for a precise diagnosis.

• OBD-II scan retrieves the stored DTC and freeze-frame data
• Common causes include EVAP leaks, misfires, and O2 sensor faults

A steady light means drive cautiously to service; a flashing light means stop driving—severe misfire can damage the catalytic converters.

On a 2016 Dodge Charger, sustained misfires overheat the converters and can escalate repair costs. If the light is steady, reduce load and avoid hard acceleration en route to our Millbury Service Center. If it flashes, safely pull over and arrange towing to prevent engine or catalyst damage. Book an appointment online to minimize risk and downtime.

• Flashing light = potential catalyst-damaging misfire
• Steady light = non-urgent fault; service soon

The top five causes are O2 sensor faults, EVAP leaks (including a loose gas cap), misfires, catalytic converter efficiency, and MAF/airflow issues.

On a 2016 Dodge Charger, codes frequently include P013x/P015x (O2), P0456/P0442 (EVAP), P030x (misfire), P0420 (converter efficiency), and P0101 (MAF range/performance). New England temperature swings can aggravate EVAP leaks, while worn plugs or coils trigger misfires. Our Millbury team verifies the root cause before any repair.

• Example codes: P0456 (small EVAP leak), P0420 (catalyst efficiency)
• Performance symptoms may include rough idle or reduced MPG
• Schedule service for a confirmed diagnosis

Parts stores read generic codes; our dealer team uses OEM scan tools and service data to pinpoint the root cause with guided tests.

Codes often have multiple possible causes on the 2016 Dodge Charger—only a full diagnostic (live data, bi-directional tests, and isolation steps) confirms the fix. Our factory-certified technicians follow Mopar procedures and provide a written estimate before work begins. That saves time and reduces unnecessary parts replacement.

• OEM scan tool access and proprietary data
• Isolation testing and a written estimate before repair

No—Massachusetts OBD emissions testing will fail vehicles with recently cleared codes or “Not Ready” monitors.

Clearing the light on a 2016 Dodge Charger resets readiness monitors; most require a complete drive cycle before inspection. If the underlying fault remains, the code will return and still fail the test. Fix the cause first, then complete the drive cycle to set monitors to Ready. Our Millbury team can verify readiness before you test.

• Do not clear codes right before inspection
• Complete the readiness drive cycle after repairs
• Schedule service to confirm monitors are Ready

Our Millbury Service Center supports Worcester County drivers—from Worcester and Auburn to Grafton, Shrewsbury, Sutton, and Oxford. New England winters can trigger cold-start faults (e.g., P0128 thermostat) and seasonal temperature swings may reveal EVAP leaks like P0456. Dealer tools allow bi-directional tests, module communication checks, and brand-specific procedures to confirm the root cause before repairs. We use genuine Mopar parts to restore performance and emissions compliance. Get directions to 2 Latti Farm Road (off Route 20) and schedule service online.

Your 2016 Dodge Charger receives a structured, step-by-step process designed to find the exact fault. We start with an initial OBD-II scan and freeze-frame review, then validate the concern with visual checks and smoke/pressure tests as needed. Next, we perform isolation testing—such as coil-on-plug swaps, circuit checks, or sensor waveform analysis—to distinguish a failed part from wiring or software issues. You receive a written estimate before any repair so you can approve the plan confidently. After repairs, we verify fixes, clear codes, and confirm readiness monitors. Ready to proceed? Use our online portal to schedule service at your convenience.

Many 2016 Dodge Charger owners see recurring OBD-II codes that point to familiar systems. P0300–P0308 indicate random or cylinder-specific misfires; ignoring them can overheat and damage catalytic converters. P0420 flags catalyst efficiency below threshold; prolonged driving with misfires can cause this. P0456 or P0442 suggest small-to-medium EVAP leaks—often a loose cap or brittle hose—leading to fuel vapor losses and failed inspections. P0101 signals MAF range/performance issues affecting drivability and MPG, while P0128 points to a thermostat running cool, which can keep monitors from setting.
