Explaining 2014 Dodge Charger Check Engine Light Codes
Contents
Hide
Every code stored by the 2014 Charger’s PCM captures critical data about what triggered the MIL. Interpreting that data properly prevents parts cannon repairs and protects the Pentastar or HEMI from avoidable failures. This guide covers how to read codes, prioritize repairs, and keep the light off long term.
- Applies to: 2014 Charger SE, SXT, R/T, AWD, and Pursuit.
- Tools: OBD-II scanner with Chrysler-specific data, graphing capability, smoke machine, digital multimeter.
- Reminder: A flashing MIL means an active misfire. Reduce load immediately and address ignition/fuel faults first.
How to Retrieve Charger DTCs
- Connect the scan tool to the OBD-II port beneath the steering column and select the PCM.
- Read active, pending, and permanent codes along with freeze-frame, fuel trims, and Mode $06$ data.
- Save or export the report; clearing codes before repairs loses valuable diagnostic detail.
- Only clear the MIL after repairs and validation drives are complete.
Top 2014 Charger Codes and First Checks
| Code | Category | Likely Causes | Rapid Checks |
|---|---|---|---|
| P0300/P0301-P0308 | Misfire | Coils, plugs, injector imbalance, vacuum leak, compression loss | Inspect plugs, swap coils, run compression/leak-down, review Mode $06$ misfire counters. |
| P2096/P2098 | Fuel Trim | Exhaust leak, intake leak, post-cat O2 bias | Smoke-test intake/exhaust, compare upstream/downstream O2 waveforms, check fuel trims. |
| P219A/P219B | Air-Fuel Imbalance | Injector flow variance, PCV failure, manifold gasket leak | Perform injector balance test, inspect PCV hoses, evaluate cylinder balance. |
| P0456 | EVAP | Loose cap, cracked vapor line, ESIM leak | Inspect cap seal, apply smoke to EVAP service port, check purge solenoid for leaks. |
| P06DE | Oil Pump Control | Incorrect oil filter, solenoid stuck, wiring fault | Verify Mopar filter installation, test mechanical oil pressure, inspect harness near oil cooler. |
Diagnostic Flow
- Misfire triage: Address ignition and fuel delivery faults first to protect catalysts.
- Align fuel trims: Use smoke testing and O2 analysis to resolve lean or rich banks before replacing sensors.
- Verify oil pump operation: Attach a mechanical gauge when P06DE/P0520 appear and inspect the filter/housing.
- Seal the EVAP system: Command purge closed, apply smoke, and repair leaks found at hoses, ESIM, or filler neck.
- Update software: Confirm PCM flash level; Chrysler updates improve misfire and oil-pressure logic.
- Validate with drive cycle: After repairs, complete a 50-mile mixed drive so all readiness monitors return to COMPLETE.
Preventive Maintenance Tips
- Follow factory spark plug intervals and torque specs to avoid coil boot damage.
- Inspect intake manifold gaskets, PCV assemblies, and purge hoses at each oil change.
- Use OEM-spec oil filter cartridges; incorrect filters commonly trigger P06DE.
- Keep software current and document calibration IDs after dealer flashes.
- Run an annual EVAP smoke test in climates with significant temperature swings.
Frequently Asked Questions
Why do codes return after clearing them?
Clearing codes without repairing the fault resets the MIL temporarily. The PCM runs the same diagnostic and logs the code again if the issue persists.
Do I need dealer tools to read Mode $06$ data?
No. Many aftermarket scan tools display Mode $06$ misfire and catalyst data so you can confirm repairs before monitors fail.
Can a dirty throttle body trigger fuel trim codes?
Yes. Carbon buildup disturbs idle airflow and can skew trims. Clean the throttle body and perform an idle relearn after service.
