2017 Dodge Charger Check Engine Light

The 2017 Charger added stop/start functionality, dual-stage oil pumps, and updated 8-speed transmissions. A lit MIL can indicate anything from misfire to battery management faults. Follow this roadmap to capture data, prioritize repairs, and confirm the light stays off.

Applies to: 2017 Charger SXT, GT AWD, R/T, Daytona, and SRT 392.
Tools: WiTech-compatible scan tool, oscilloscope for O2 sensor verification, smoke machine, fuel pressure transducer, battery tester.
Safety alert: A flashing MIL signals a severe misfire; reduce load immediately.

Frequent 2017 Charger Codes

Code	System	Meaning	First Checks
P0300/P030x	Ignition/Fuel	Random or cylinder-specific misfire	Inspect plugs/coils, verify injector pulse, analyze Mode $06$ misfire counts.
P2096/P2098	Fuel Trim	Post-catalyst fuel trim too lean	Check for exhaust leaks, monitor upstream/downstream O2 waveforms, evaluate fuel trims.
P0335	Crankshaft Position	CKP circuit performance	Inspect wiring near bellhousing, confirm sensor output with scope, check for metal debris.
P06DD/P06DE	Oil Pump Control	Dual-stage oil pump stuck	Verify correct oil filter, measure mechanical oil pressure, inspect wiring at oil cooler.
P1DF3	Stop/Start	Performance fault in stop/start system	Test main and auxiliary batteries, inspect ground straps, update PCM/TCM software.

Diagnostic Workflow

Verify software levels: Record PCM, TCM, and ABS flash IDs; update if TSBs address misfire, fuel trim, or stop/start issues.
Capture data: Save DTCs, freeze-frame snapshots, Mode $06$ results, and fuel trims before clearing anything.
Resolve misfires: Replace worn plugs, swap coils, confirm injector performance, and review compression data.
Diagnose fuel trim faults: Smoke-test intake/exhaust and inspect manifold studs before condemning sensors.
Check oil pump operation: For P06DD/P06DE, confirm the correct filter cartridge and verify pressure at idle and 3,000 rpm.
Troubleshoot stop/start: Load-test both batteries, inspect grounds, and perform stop/start relearn after repairs.
Complete drive cycle: After repairs, drive 10–15 miles with varied speeds to reset monitors and confirm no pending codes remain.

Driving Guidance

Reduce throttle immediately when the MIL flashes or the engine runs rough.
Stop/start or EVAP-only codes allow limited driving, but complete repairs before inspection deadlines.
Monitor oil pressure, coolant temperature, and transmission temperature during diagnosis.

Preventive Maintenance Checklist

Replace spark plugs at 100,000 miles on the 3.6L and 30,000 miles on the 5.7L; torque coils properly.
Use Mopar-approved 0W-20 or 5W-20 oil and filters to support dual-stage pump operation.
Inspect intake/exhaust manifolds yearly for leaks that skew fuel trims.
Test both batteries twice a year; weak auxiliary batteries commonly trigger P1DF3.
Keep PCM/TCM calibrations current for improved misfire detection and stop/start strategy.

Frequently Asked Questions

Does disabling stop/start clear P1DF3?

No. The PCM still logs the fault. Diagnose battery health, wiring, and software instead of turning the feature off.

Can the wrong oil filter cause P06DD?

Yes. Non-OEM filters can restrict oil flow or block the bypass valve. Always use the specified cartridge and torque the housing to spec.

How long do monitors take to reset?

Plan for 40–60 miles of mixed driving (city, steady cruise, idle) after clearing codes to complete misfire, catalyst, and EVAP monitors.
