Investigating P0441 on Your 2021 Ford Bronco Sport
A P0441 code on your 2021 Ford Bronco Sport indicates incorrect purge flow in the EVAP system. The Bronco Sport (not to be confused with the body-on-frame Bronco) shares the Ford Escape's C2 platform and offers a 1.5L EcoBoost three-cylinder (Base/Big Bend/Outer Banks) or a 2.0L EcoBoost four-cylinder (Badlands/First Edition). P0441 targets the purge circuit — the purge valve and vacuum lines routing fuel vapors to the engine.
How P0441 Sets
The PCM commands the purge valve open during steady driving and monitors the FTP sensor for expected pressure response. When measured purge flow doesn't match programmed values, P0441 stores. The Bronco Sport uses Ford's capless fueling system.
Primary Suspects
- Purge Valve Failure (35% likelihood) — The leading suspect. After 3–4 years of EcoBoost turbo heat cycling, internal seal degradation can restrict flow. Part: $30–$70. Labor: $55–$110.
- Vacuum Line Issue (20% likelihood) — Turbo heat and potential off-road vibration stress hoses. The 1.5L three-cylinder and 2.0L four-cylinder have different routing but similar vulnerability. Repair: $12–$45. Labor: $30–$80.
- Capless Filler Neck (15% likelihood) — Off-road-oriented Bronco Sports encounter more dirt. Debris in the capless filler affects sealing. Clean the filler opening first. Replacement: $80–$190.
- Canister Vent Solenoid (10% likelihood) — Affects pressure dynamics during purge testing. Part: $40–$90. Labor: $85–$170.
- Charcoal Canister (10% likelihood) — From overfilling. Part: $110–$270. Labor: $90–$175.
- FTP Sensor (5% likelihood) — Inaccurate readings. Part: $40–$95. Labor: $55–$110.
- Wiring/Connector (5% likelihood) — Corrosion from moisture or trail exposure.
Off-Road Considerations
If you use your Bronco Sport on trails (especially Badlands trim), underbody EVAP components are exposed to water, mud, and impacts. Inspect the charcoal canister, vent solenoid, and EVAP lines near the rear for damage, water intrusion, or connector corrosion.
Warranty Status
Ford's 3-year/36,000-mile warranty may still apply for a 2021 model depending on purchase date. The 5-year/60,000-mile powertrain warranty and 8-year/80,000-mile federal emissions warranty provide additional coverage. Check with your dealer before paying for repairs.
FORScan DIY Diagnosis
FORScan with a compatible OBD-II adapter provides full EVAP diagnostic access — purge valve command, FTP monitoring, and system self-tests. This helps identify the cause before a shop visit.
Repair Costs
Purge valve: $85–$180. Vacuum lines: $42–$125. Capless filler: $135–$300. Vent solenoid: $125–$260. Charcoal canister: $200–$445.
