What P0175 Means for Your 2022 Dodge Durango
When your 2022 Dodge Durango displays a P0175 code, the powertrain control module (PCM) has detected that bank 2 is running richer than the target air-fuel ratio. The 2022 Durango is available with the 3.6L Pentastar V6 (295 hp) or the 5.7L HEMI V8 (360 hp), and on higher trims, the 6.4L HEMI V8 in the SRT 392. Bank 2 location varies: on the V6, it's the rear bank closest to the firewall; on the V8 engines, it's the passenger side.
Warning Signs of a Rich Condition
- Check engine light illuminated
- Reduced fuel economy — especially impactful on the HEMI V8 models where MPG is already a consideration
- Dark or black exhaust smoke during acceleration
- Rough or unstable idle
- Strong exhaust fuel odor
- Possible spark plug fouling on bank 2 cylinders
Root Causes on the 2022 Durango
1. Dirty or Failed Mass Airflow Sensor
The MAF sensor remains the most common trigger for P0175 across all Durango engine options. On the 2022 model year, the sensor is located between the air filter housing and the throttle body. Dust, dirt, or oil film on the sensing element causes inaccurate airflow readings. The PCM responds by delivering more fuel than needed. A $10 can of MAF sensor cleaner often resolves this. If the sensor has failed electronically, a replacement runs $95–$210.
2. Fuel Injector Leak or Malfunction
The 2022 Durango's fuel injectors operate under precise electronic control. Injectors on bank 2 that are stuck partially open, leaking at the tip, or delivering fuel in poor spray patterns will enrich that bank. On the 3.6L Pentastar, injector O-ring deterioration is a documented issue. On the HEMI, carbon buildup can affect injector seating. Professional cleaning costs $130–$240; replacement runs $60–$120 per injector plus labor.
3. Upstream O2 Sensor on Bank 2
The heated oxygen sensor positioned before the catalytic converter on bank 2 provides real-time air-fuel mixture data. A biased or lazy sensor that reads lean when the mixture is actually correct will cause the PCM to add fuel, creating a rich condition. Sensor replacement on the 2022 Durango costs $140–$290 including parts and labor.
4. Excessive Fuel Pressure
The Durango uses a returnless fuel delivery system with an in-tank fuel pump and integrated pressure regulator. If fuel pressure runs above specification (normally 58 psi ±5), all injectors deliver excess fuel. Diagnosing this requires a fuel pressure gauge. The fuel pump module replacement runs $320–$580 on the 2022 Durango.
Diagnostic Procedure
- Read all stored DTCs — note if P0172 is also present (both banks rich suggests MAF or fuel pressure)
- Check freeze frame data for engine load, RPM, and coolant temperature when the code set
- Observe live fuel trim data — LTFT bank 2 consistently below -10% confirms the issue
- Inspect and clean the MAF sensor
- Verify fuel pressure at the Schrader valve on the fuel rail
- Use a scope or advanced scan tool to analyze O2 sensor response time on bank 2
Safe to Drive?
For daily commuting, you can drive for a short period with P0175. However, the 2022 Durango is often used as a family hauler and tow vehicle. Avoid towing with this code active, as increased load worsens the rich condition. Catalytic converter replacement on the Durango runs $900–$1,400, making timely repair a financially smart choice.
Warranty and DIY Notes
The 2022 Durango carries a 5-year/60,000-mile powertrain warranty. If your vehicle is still within coverage, have the dealer diagnose it first. For DIY owners, MAF sensor cleaning is a 15-minute job. O2 sensor replacement is manageable with basic tools and a sensor socket. Fuel system work beyond that is best handled by a qualified technician.
