2023 Dodge Charger Check Engine Light in Millbury, MA

It means the OBD-II system detected a fault and stored a diagnostic trouble code (e.g., P0442 for an EVAP small leak).

Your 2023 Dodge Charger’s engine computer monitors systems like fuel, ignition, and emissions; when a fault occurs, it sets a code and turns on the light. Some issues are minor (loose gas cap), while others require immediate attention (misfires or catalyst efficiency). Our Millbury team uses factory scan tools to read codes, review freeze-frame data, and confirm the cause.

• Examples: P0300–P0306 (misfire), P0420 (catalyst), P0457 (loose gas cap)
• Stable light: drive cautiously to diagnosis; flashing: stop to prevent damage
• Book a dealer-level code read and test: schedule service

Common causes include EVAP leaks (P0442/P0457), misfires (P0300–P0306), oxygen sensor faults (P013x/P015x), and catalyst efficiency (P0420).

The 3.6L V6 in the 2023 Dodge Charger can set codes for loose or failing gas caps, aging O2 sensors, coil or plug misfires, or exhaust catalyst issues. Left unaddressed, misfires can overheat the catalytic converter. We serve Millbury and Worcester County with Mopar diagnostics to pinpoint the exact fault before you spend on parts.

• EVAP small leak may be as simple as a cap seal or a cracked hose
• Misfires can stem from spark plugs, coils, or fuel delivery

A flashing light signals a severe misfire—stop driving; a steady light means drive cautiously and schedule diagnosis soon.

On the 2023 Dodge Charger, a flashing light can quickly damage the catalytic converter and should be addressed immediately. If the light is steady and the car runs normally, reduce load (avoid hard acceleration) and get it checked promptly. Our Millbury location provides same-day diagnostics when available.

• Flashing = misfire risk to catalyst; steady = non-urgent but important
• Note drivability symptoms (rough idle, hesitation, odors) for your technician
• Reserve a diagnostic slot now: schedule service

A parts store can read a generic P-code for free, but dealer diagnostics use factory wiTECH tools to access Dodge-specific data and perform pinpoint tests.

Codes are starting points, not answers—each has multiple possible causes. Our certified team in Millbury reviews freeze-frame data, runs system tests, and verifies the actual fault to avoid unnecessary parts. You’ll receive a written estimate before repairs so you can decide next steps with confidence.

• Factory scan access to all modules and proprietary data
• Isolation testing to confirm cause, not just read a code
• Book online and arrive prepared: schedule service

No—resetting clears OBD-II readiness monitors, and most MA inspections fail vehicles with unset monitors.

Clearing codes erases data the inspector needs to verify your 2023 Dodge Charger’s emissions systems are working. Many monitors require a complete drive cycle to reset, and the light may return if the fault persists. Fixing the underlying issue is the reliable path to a pass.

• Unset monitors often trigger an automatic fail at inspection
• Underlying faults can return once monitors complete
• Get a verified diagnosis: schedule service

Yes—a loose or worn cap can set EVAP leak codes like P0457 and turn on the light.

In Central Massachusetts, temperature swings can stress EVAP seals; if the cap isn’t tight (or the seal is cracked), your 2023 Dodge Charger may store small-leak EVAP codes. Tighten until you hear clicks and drive; if the light stays on, the system needs smoke testing to find leaks.

• Tighten the cap; inspect the rubber seal for cracks
• If light persists, EVAP smoke testing isolates the leak path
• Check current service specials and schedule

Our diagnostic process for the 2023 Dodge Charger is methodical and transparent. First, we perform an initial OBD-II scan with factory wiTECH to capture all stored and pending codes plus freeze-frame data. Next, a technician reviews live data and confirms symptoms. Then we conduct isolation testing tailored to the Charger’s 3.6L V6—this may include smoke testing the EVAP system, coil/plug checks for misfires, exhaust backpressure evaluations for catalyst concerns, and intake/vacuum integrity checks. Youll receive a written estimate before any repair, outlining verified causes and recommended fixes. Prefer to plan ahead? View current service specials and reserve your visit online. When youre ready, schedule service for a clear, no-surprise path to a repaired and reset system.

The 2023 Dodge Charger may display several frequently seen powertrain codes. Misfire codes P0300randomand P0301P0306 (cylinders 16) can indicate worn spark plugs, coil issues, or fuel delivery problems; ignoring them can overheat and damage the catalytic converters. EVAP system codes like P0442 (small leak) or P0457 (loose gas cap) often relate to cap seals or hoses. Oxygen sensor and catalyst efficiency codes such as P013x/P015x and P0420 may point to aging sensors or an underperforming catalyst, which can raise emissions and fuel use. Addressing causes early typically reduces repair costs and prevents secondary damage.
