Premium Case File: P0441 in the 2024 Grand Wagoneer
Your 2024 Jeep Grand Wagoneer has logged P0441 — Evaporative Emission Control System Incorrect Purge Flow. An unwelcome code on Jeep's most luxurious offering, but one that's fully covered under warranty. The 2024 Grand Wagoneer offers the 6.4-liter Apache V8 (471 hp) or the available Hurricane twin-turbo 3.0-liter inline-six (510 hp) — both mated to an 8-speed automatic with Quadra-Drive II full-time 4x4. The EVAP system captures fuel vapors from the large rear-mounted tank and routes them to the engine, and P0441 means the PCM detected abnormal purge flow during its diagnostic self-test.
What the Displays Show
- Check engine light on the digital instrument panel
- Full engine performance maintained (V8 or Hurricane I6)
- All luxury and comfort features operational
- Possible subtle fuel odor
- Emissions test failure if applicable
Tracing the Cause
1. PCM Software Calibration
The Grand Wagoneer platform continues to receive software refinements, especially for the newer Hurricane twin-turbo I6 option. A PCM update via wiTECH 2.0 is the most common P0441 resolution on new Grand Wagoneers.
2. Purge Solenoid Valve Defect
Whether equipped with the V8 or the Hurricane I6, a factory-defective purge solenoid triggers P0441 immediately. The Hurricane engine's higher turbo heat puts additional thermal stress on this component.
3. ESIM Module Manufacturing Issue
The ESIM monitors EVAP integrity from its underbody position. A defective unit from the factory produces incorrect system readings during the PCM's self-test routine.
4. EVAP Hose Routing or Connection Error
The Grand Wagoneer's full-size chassis requires the longest EVAP hose routing of any Jeep. Factory connection issues along this extended path are more likely than on smaller vehicles.
5. Fuel Tank Overfilling
The Grand Wagoneer's substantial fuel capacity tempts drivers to top off. Overfilling past the first nozzle click damages the charcoal canister, regardless of vehicle age.
Diagnostic Steps
- Contact your dealer — your 2024 Grand Wagoneer has full factory warranty
- The dealer will use wiTECH 2.0 to scan codes and check for software updates
- PCM calibration will be updated if a newer version is available
- If software is current, component-level testing identifies the issue
- A smoke test reveals any physical EVAP leaks

Can I Drive With P0441?
Yes. Whether you chose the 471-hp V8 or the 510-hp Hurricane I6, every bit of power is intact. P0441 is an emissions monitoring code only — it affects nothing about the driving experience, towing capability, or luxury features of your Grand Wagoneer.
