P0175 on the 2023 Dodge Charger: Final ICE Generation
The 2023 Dodge Charger represents the last model year of the internal combustion engine Charger before the transition to the electric Charger Daytona. Available with the 3.6L Pentastar V6, 5.7L HEMI V8, 6.4L HEMI Scat Pack, and the supercharged Hellcat variants, the 2023 Charger carries the final evolution of these legendary powertrains. P0175 on any of these engines means Bank 2 is running too rich for the ECM to correct.
With the ICE Charger ending production, maintaining these engines well is especially important for preserving value. Addressing P0175 promptly keeps the engine running at its best.
Symptoms
- Check engine light on
- Fuel economy below expected levels
- Rough idle on the V8 models
- Rich exhaust smell
- Black residue on exhaust tips
- MDS cylinder deactivation issues on HEMI models
- Reduced performance feel
Causes on the 2023 Charger
1. MAF Sensor Contamination — High Likelihood
Even at relatively low mileage, the MAF sensor can accumulate contamination from PCV oil vapors and road debris. Charger owners who enjoy the car's performance capabilities generate more crankcase blowby from high-RPM driving, which accelerates MAF contamination. The HEMI's massive airflow demands make accuracy especially critical.
2. O2 Sensor Issue — Medium Likelihood
On a newer 2023 model, O2 sensor failure is less likely from wear but possible from a factory defect. Performance driving generates extreme exhaust temperatures that can reveal marginal sensor quality. Testing with a Stellantis scanner identifies response time issues.
3. Fuel Injector Issue — Medium Likelihood
The HEMI's multi-port injectors and the Pentastar's direct injectors are both precision components. Even at low mileage, a manufacturing defect in a single injector can cause over-delivery on Bank 2. Carbon buildup on Pentastar DI injectors begins early and can alter spray patterns.
4. Software or EVAP Issue — Low Likelihood
A Stellantis ECM software update or EVAP purge valve issue could cause P0175 on a newer model. Both are inexpensive fixes that the dealer can check during warranty diagnosis.
Diagnostic Steps
- Take it to the Dodge dealer — warranty coverage applies
- Scan with wiTECH or equivalent Stellantis scanner
- Compare fuel trims between banks
- Test MAF and O2 sensors against specifications
- Check for TSBs and software updates
Repair Costs
- MAF sensor: $80–$230
- O2 sensor: $100–$290
- Fuel injector (each): $60–$350
- EVAP purge valve: $60–$150
Covered under the 3-year/36,000-mile warranty.
Preserve the Last ICE Charger
As the final internal combustion Charger, the 2023 model is poised to become a collector's item. Keeping the engine in top condition by addressing codes like P0175 promptly protects both performance and long-term value. Use the dealer warranty for repairs and keep detailed service records.
