Why the 2013 Dodge Charger Check Engine Light Matters
Contents
Hide
The 2013 Charger introduced improved PCM logic, yet the MIL still points to ignition, lubrication, or EVAP faults that can escalate quickly. Treat every code as a roadmap—capture data, correct the root cause, and prove the repair with a complete drive cycle.
- Applies to: 2013 Charger SE, SXT, R/T, R/T Plus, AWD, and Pursuit trims.
- Tools: Enhanced scan tool, Mode $06$ access, mechanical oil-pressure gauge, EVAP smoke machine.
- Immediate reminder: A flashing MIL signals a catalyst-threatening misfire. Reduce throttle and diagnose before further driving.
High-Priority 2013 Charger Codes
| Code | System | Likely Cause | First Response |
|---|---|---|---|
| P0300/P030x | Ignition/Fuel | Coils, plugs, injector imbalance, compression loss | Review Mode $06$ misfire data, inspect plugs/coils, perform compression test. |
| P0520/P06DE | Lubrication | Oil pressure sensor or dual-stage pump fault | Verify oil level, confirm correct Mopar filter, check mechanical pressure hot at idle and 3,000 rpm. |
| P2096/P2098 | Fuel Trim | Vacuum leak, exhaust leak, post-cat O2 fault | Smoke-test intake/exhaust, inspect manifold studs, monitor STFT/LTFT. |
| P0456/P0457 | EVAP | Loose cap, ESIM leak, purge solenoid failure | Replace the fuel cap if worn, seal the system, and inject smoke to locate leaks. |
| P1CEA | Torque Management | AWD clutch pressure adaptation | Check software version, inspect ATF, perform relearn with scan tool if applicable. |
Structured Diagnostic Workflow
- Record baseline data: Save DTCs, freeze-frame snapshots, fuel trims, and Mode $06$ results before clearing anything.
- Resolve misfires: Replace overdue spark plugs, swap coils, and use injector balance tests to confirm fuel delivery.
- Verify oil pressure: If P0520/P06DE are present, attach a mechanical gauge; minimum 20 psi hot idle, 45 psi at 3,000 rpm.
- Fix fuel trim faults: Inspect intake manifold gaskets, PCV hoses, and exhaust flange gaskets; repair leaks before replacing sensors.
- Test EVAP integrity: Command purge closed, seal the system, and smoke-test ESIM, filler neck, and purge solenoid connections.
- Update software if needed: Apply PCM flashes (TSBs 18-046-13, 18-019-14) to refine misfire detection and oil-pressure strategy.
- Complete the drive cycle: Follow Chrysler’s sequence (idle, steady 45 mph, decel, highway cruise) and confirm monitors return to COMPLETE.
Driving Guidance During Diagnosis
- A flashing MIL or severe vibration means stop driving and repair immediately.
- EVAP-only codes allow limited driving, but fix them before inspection deadlines.
- Watch the oil-pressure warning lamp and coolant gauge; shut down if readings drift outside normal range.
Preventive Maintenance
- Use API SN 5W-20 oil and Mopar MO-349 filters to maintain correct pump control.
- Inspect exhaust manifold studs and gaskets at each oil change to prevent lean post-cat codes.
- Clean the throttle body annually and perform an idle relearn after battery disconnects.
- Replace the engine air filter every 15,000 miles to keep MAF data stable.
- Keep PCM software up to date to benefit from refined misfire logic.
Frequently Asked Questions
Will disconnecting the battery clear the light permanently?
No. Battery disconnects erase adaptives briefly, but the PCM will flag the same fault on the next drive if the issue persists.
Is it safe to drive with only P0456?
Yes, but repair the EVAP leak soon so readiness monitors can set before inspection.
No. Stick to the recommended octane. Misfires stem from ignition, fuel, or mechanical faults that must be fixed.
