Decoding the P0440 on Your 2024 Acura Integra
A P0440 code on your 2024 Acura Integra means the PCM has detected an EVAP system malfunction. Your sport compact is fully covered under Acura's warranty, making this a straightforward dealer visit.
The 2024 Integra EVAP System
The Integra with its 1.5L turbo (or 2.0L turbo Type S) uses Honda/Acura's EVAP design:
- PCSV — Purge Control Solenoid Valve for vapor routing
- Bypass Solenoid — Honda-specific vapor management
- Vent Shut Valve — System sealing for leak tests
- Charcoal Canister — Vapor storage
- FTP Sensor — Fuel tank pressure monitoring
- Fuel Filler Cap — Primary system seal
Most Likely Causes
- Gas Cap Issue (35%) — Not fully seated. Cost: $0.
- Factory Assembly Issue (22%) — EVAP connection from production. Cost: $0 under warranty.
- PCSV Defect (15%) — Factory purge valve fault. Cost: $0 under warranty.
- Software Update (12%) — PCM calibration. Cost: $0 under warranty.
- Vent Valve Issue (10%) — Not sealing. Cost: $0 under warranty.
- Bypass Solenoid (6%) — Honda-specific. Cost: $0 under warranty.
Acura Warranty

Check the gas cap first. If the code persists, your Acura dealer handles the rest at no cost.
The Verdict
The P0440 on your 2024 Integra is a warranty repair. Check the gas cap, then let the dealer diagnose using Honda's HDS system. Whether you have the base 1.5T or the Type S 2.0T, the EVAP system and coverage are the same.
