Investigating P0441 on Your 2024 Ram 2500
Your 2024 Ram 2500 heavy-duty truck has flagged P0441 — incorrect purge flow in the EVAP system. This code applies to the 6.4-liter HEMI V8 gas engine (410 hp, 429 lb-ft). If you have the 6.7L Cummins turbo diesel, EVAP codes aren't applicable. On a brand-new heavy-duty truck, P0441 is almost always a warranty-covered issue — either a component defect or software calibration needing an update.
Symptoms You Might Notice
- Steady check engine light
- Normal 6.4L HEMI power and towing performance
- No 4WD or transmission issues
- Possible fuel odor near the bed area
Common Causes on a New Ram 2500
1. ESIM Manufacturing Defect
The ESIM (Evap System Integrity Monitor) near the charcoal canister can have factory defects. Stellantis has issued TSBs for ESIM issues on heavy-duty Ram trucks, and your dealer can check for applicable service campaigns.
2. PCM Software Calibration
Stellantis releases software updates for EVAP monitor parameters, especially on updated model years. A wiTECH 2.0 flash can resolve false P0441 triggers without any parts replacement.
3. Purge Solenoid Valve Defect
A factory-defective purge solenoid that doesn't actuate properly under the 6.4L HEMI's operating conditions. The heavy-duty engine bay runs hot, and marginal valves are exposed early.
4. Assembly-Line EVAP Connection
The 2500's extended EVAP plumbing has many connection points along the frame rail. A single connection not fully seated at the factory can create a small leak that triggers P0441.
What to Expect at the Dealer
- Drop off your Ram 2500
- Technician connects wiTECH 2.0 and pulls diagnostic data

Can I Drive With P0441?
Yes. Your Ram 2500 is fully operational. P0441 doesn't affect the 6.4L HEMI, Aisin transmission, 4WD, or any towing/hauling capability. Continue working while scheduling the dealer visit.
DIY vs Professional
Take it to the Ram dealer. Your 2024 Ram 2500 is covered under Stellantis's 3-year/36,000-mile basic warranty and 5-year/60,000-mile powertrain warranty. EVAP components qualify for federal emissions warranty (8 years/80,000 miles). The repair is free.
