A New Trail to Follow: P0441 in Your 2024 Gladiator
Your 2024 Jeep Gladiator has set P0441 — Evaporative Emission Control System Incorrect Purge Flow. An unexpected code on a new truck, but an easy case to close when you're under factory warranty. The 2024 Gladiator continues on the JT platform with the 3.6-liter Pentastar V6 (285 hp), available in both 6-speed manual and 8-speed automatic. The EVAP system uses Stellantis's ESIM (Evap System Integrity Monitor) and a purge/vent solenoid pair to manage fuel vapor recovery across the truck's extended frame. P0441 tells us the PCM detected purge flow outside the expected range during a self-diagnostic test.
What the Dashboard Reveals
- Steady check engine light
- No performance or towing capacity changes
- Possible subtle fuel odor
- All 4x4 modes fully operational
- Emissions test failure if applicable
Tracking the Source
1. PCM Software Calibration Issue
Stellantis continues to release software refinements for the Gladiator platform. A PCM update via wiTECH 2.0 that adjusts EVAP monitor thresholds is the most common resolution on newer Gladiators.
2. Purge Solenoid Valve Manufacturing Defect
Even on a brand-new truck, a solenoid that doesn't meet factory tolerances will trigger P0441 immediately when the PCM runs its first EVAP self-test. This is the most common component failure.
3. ESIM Module Defect
The ESIM monitors EVAP system pressure changes from its underbody position. A factory-defective module produces incorrect readings that appear as purge flow errors in the PCM's diagnostic routine.
4. EVAP Hose Assembly Error
The Gladiator's long-wheelbase frame requires extensive EVAP hose routing. A slightly loose factory connection or a hose routed too close to heat sources can trigger P0441 without any component defect.
5. Charcoal Canister Overloading
Topping off the fuel tank past the first nozzle click floods the canister with liquid fuel. Even on a new truck, this habit can trigger EVAP codes within weeks.
Diagnostic Steps
- Bring it to the dealer — your 2024 Gladiator has full warranty coverage
- The dealer scans with wiTECH 2.0 and checks for available TSBs
- PCM software is updated if a newer calibration exists
- If software is current, component testing identifies the faulty part
- A smoke test reveals any physical EVAP leaks
Repair Cost Breakdown
- All warranty repairs: $0
- PCM software update: $0
- Purge solenoid (reference): $150–$350
- ESIM module (reference): $200–$400
- EVAP hose repair (reference): $100–$300
Can I Drive With P0441?
Yes. P0441 has zero effect on your Gladiator's 3.6L Pentastar engine, towing capacity, payload, or 4x4 system. Continue using your truck normally while you schedule a convenient dealer visit.
DIY vs. Professional Repair
Take it to the dealer — no question. Your 2024 Gladiator is under Jeep's full 3-year/36,000-mile basic warranty and 5-year/60,000-mile powertrain warranty. All EVAP repairs, from software updates to component replacement, are covered at no cost. Don't void your warranty coverage with DIY work on a brand-new truck.
