Tracking P0455 on Your 2022 Mitsubishi Outlander
A P0455 on your 2022 Outlander (all-new 4th generation on the Nissan Rogue platform) indicates a large EVAP leak. The 2.5L I4 uses a Mitsubishi/Nissan EVAP system. Mitsubishi's 5-year/60,000-mile warranty runs through 2027.
Clues
- Check engine light on
- P0455 stored in ECU
- Possible fuel smell
- Gas cap not clicking
Suspects Ranked
- Gas Cap Seal (Very High Likelihood): Loose or worn. $0–$20.
- Purge Control Solenoid (Medium Likelihood): Mitsubishi EVAP valve. $100–$240 installed.
- Vent Control Valve (Medium Likelihood): Sticking. $110–$250 installed.
- Charcoal Canister (Low-Medium Likelihood): Saturation. $220–$400 installed.

Diagnosis
Gas cap first. Drive 2–3 days. If P0455 returns, your Mitsubishi dealer with MUT-III diagnostics or a smoke test will find the leak.
