Uncovering P0455 on Your 2022 Lincoln Aviator
A P0455 on your 2022 Aviator signals a large EVAP leak. Whether you have the 3.0L twin-turbo V6 or the Grand Touring PHEV, the EVAP system uses Ford's canister vent solenoid. Lincoln's 4yr/50k warranty runs through 2026.
Clues
- Check engine light on
- P0455 stored in PCM
- Possible fuel odor
- Gas cap issue
Suspects Ranked
- Gas Cap Seal (Very High Likelihood): Loose or worn. $0–$25.
- Canister Vent Solenoid (Medium Likelihood): Ford EVAP valve. $130–$280 installed.
- Purge Valve (Medium Likelihood): Sticking. $110–$250 installed.
- EVAP Canister (Low-Medium Likelihood): Saturation. $220–$420 installed.
- Fuel Tank Deformation Valve (Low Likelihood): Ford-specific. $140–$300 installed.
Diagnostic Path
Gas cap first. If P0455 persists, your Lincoln dealer with IDS diagnostics will pinpoint the issue. The Aviator Grand Touring PHEV has the same gas-side EVAP system.
Warranty
Lincoln's 4yr/50k warranty runs through 2026. Federal emissions (8yr/80k) covers EVAP through 2030.
Safe to Drive?
Yes. P0455 doesn't affect the twin-turbo V6, PHEV system, AWD, air suspension, or any features.
