P0175 on the 2022 Dodge Charger
The 2022 Dodge Charger offers the 3.6L Pentastar V6 (292 hp), 5.7L HEMI V8 (370 hp), 6.4L HEMI Scat Pack (485 hp), and the supercharged 6.2L Hellcat variants. All have V-configuration engines with a true Bank 2. At 2-4 years old with 20,000-55,000 miles, the 2022 Charger sits at the intersection where sensor contamination begins to cause issues, especially for drivers who enjoy the car's performance capabilities.
P0175 indicates Bank 2 is running richer than the ECM can compensate for. On the Charger, this means excess fuel delivery on the passenger side (HEMI) or rear bank (Pentastar), wasting fuel and potentially damaging the catalytic converter.
Symptoms
- Check engine light on
- Fuel economy worse than usual for your engine type
- Rough idle — especially noticeable on V8 models at low RPM
- Rich exhaust smell under acceleration
- Black soot on the chrome exhaust tips
- HEMI MDS may not engage properly
- Car feels down on power during spirited driving
Causes for the 2022 Charger
1. MAF Sensor Contamination — High Likelihood
The Charger's intake system draws significant air through the front grille and past the MAF sensor. After 20,000+ miles, PCV oil vapor contamination and road debris degrade the MAF element's accuracy. On the HEMI engines, the V8's enormous airflow demands make even small MAF errors significant. The Pentastar V6 is similarly affected. Charger owners who frequently drive hard generate more crankcase blowby, which accelerates MAF contamination.
2. O2 Sensor Degradation — Medium Likelihood
The upstream O2 sensor on Bank 2 endures high exhaust temperatures, especially during performance driving. Hard acceleration and sustained high RPM generate extreme exhaust heat that ages the sensor's ceramic element. A degraded sensor causes the ECM to overcompensate with fuel. At 20,000-55,000 miles, this is more common on Chargers driven aggressively.
3. Fuel Injector Issues — Medium Likelihood
The HEMI engines use multi-port injection with large-flow injectors. At moderate mileage, injector seals and pintles can develop wear, causing slight over-delivery or drip. The Pentastar V6's direct injectors can develop carbon deposits that alter spray patterns. Either condition enriches Bank 2.
4. Fuel Pressure Regulator — Low Likelihood
The fuel pressure regulator maintains consistent rail pressure. If it sticks at a higher-than-specified setting, all Bank 2 injectors receive excess fuel pressure and over-deliver. This is less common on newer vehicles but worth checking if other causes are eliminated.
Diagnostic Steps
- Scan with a Stellantis-compatible scanner
- Compare fuel trims between banks at idle and 2,000 RPM
- Test MAF sensor against specifications for your engine variant
- Monitor O2 sensor response on Bank 2
- Check fuel pressure at rail
- Run injector balance test if needed
Repair Costs
- MAF sensor: $80–$230
- O2 sensor: $100–$290
- Fuel injector (each): $60–$200 (HEMI) / $130–$350 (Pentastar)
- Fuel pressure regulator: $120–$300
DIY Options
The 2022 Charger has good engine bay access, especially on V8 models. MAF sensor is a quick swap. O2 sensors require getting underneath. HEMI injector work is moderate difficulty. The Charger community has extensive DIY documentation. If under warranty, the dealer handles it first.
