P0175 on the 2024 Ram 2500 Gas Model
The 2024 Ram 2500 gas variant is powered by the proven 6.4L HEMI V8 producing 410 hp and 429 lb-ft of torque. This heavy-duty V8 uses multi-port fuel injection and a Variable Valve Timing (VVT) system. Bank 2 on the 6.4L HEMI is the passenger side, containing cylinders 2, 4, 6, and 8. A P0175 code means the ECM has detected a rich fuel mixture on Bank 2 that exceeds the fuel trim correction capability.
On a new or nearly new 2024 model, P0175 is less common and typically points to a component defect or contamination issue rather than wear. The good news is full warranty coverage.
Symptoms
- Check engine light on
- Fuel economy below the expected 12-17 MPG range
- Rough idle
- Rich exhaust smell
- Black soot on the tailpipe
- Possible reduction in towing performance
Causes on the 2024 Ram 2500 6.4L HEMI
1. MAF Sensor Issue — High Likelihood
Even on a new truck, the MAF sensor can be affected. Ram 2500 owners often put their trucks to work immediately — construction sites, farms, unpaved roads. These environments accelerate MAF sensor contamination significantly. A factory-defective sensor is also possible. The 6.4L's enormous airflow demands make MAF accuracy critical — at full throttle, this engine consumes over 600 CFM, and a small percentage error creates a large absolute fuel metering mistake.
2. O2 Sensor Defect — Medium Likelihood
A manufacturing defect in the Bank 2 upstream O2 sensor can cause inaccurate mixture feedback at any mileage. The 6.4L HEMI generates high exhaust temperatures that can stress even a new sensor if there's an internal weakness. Factory testing catches most defective sensors, but some slip through quality control.
3. Fuel Injector Manufacturing Issue — Medium Likelihood
On a new engine, a fuel injector that's slightly out of tolerance can cause over-delivery on Bank 2. The 6.4L's injectors are calibrated for precise fuel delivery, and any injector flowing more than its specification contributes to a rich condition. This is uncommon but possible on any new vehicle.
4. ECM Software Calibration — Low Likelihood
Ram occasionally releases ECM software updates that refine fuel delivery, sensor thresholds, and emission parameters. A 2024 Ram 2500 with P0175 at very low mileage may benefit from a software reflash at the dealership.
What to Do
- Schedule a Ram dealer appointment — this is fully covered under warranty
- Document symptoms and when they occur
- Let the dealer diagnose with wiTECH diagnostic equipment
- Ask about TSBs or software updates for the 6.4L HEMI
Cost Estimates (If Out of Warranty)
- MAF sensor: $100–$250
- O2 sensor: $120–$300
- Fuel injector (each): $80–$200
