2016年3月31日 · Just as another datapoint, my '10 Tacoma with the 2.7L 4cyl & 80k miles showed a check engine light & trac control light, & threw the 0441 & 0455 codes, but upon filling the tank, I noticed that the gas cap was a little loose.

When your Toyota's P0441 is triggered, it usually indicates a bad vacuum switch or a leak in the EVAP system that is preventing fuel vapors from reaching the canister. The P0441 code can also indicate a faulty or "stuck" PCV, a short circuit in the feed circuit, or a faulty purge solenoid.

2022年8月31日 · The P0441 code means that the control module has detected a leak in the Evaporative Emission (EVAP). A loose fuel tank filler gas cap is the most common cause that triggers the P0441 code. 5 hours after the ignition switch is turned off, the leak detection pump creates negative pressure (vacuum) in the Evaporative Emission (EVAP) system.

2024年8月5日 · The P0441 engine codes in Toyota cars can be caused by a loose gas cap, a stuck purge valve, an impermeable charcoal canister, a leak in the EVAP hoses, or an ECM that is not working.

I just checked my gas cap seal and it looks good as do the evap hoses.

2023年11月14日 · P0441 means "Evaporative Emission Control System - Incorrect Purge Flow". That typically means the ECM has detected a leak in the EVAP system. That typically happens with a loose fuel tank filler cap. It sounds like yours only fails the test intermittently, so it isn't consistent enough to set an active code and turn the check engine light on.
