P0455 on Your 2022 Jeep Wrangler
A P0455 on your 2022 Wrangler JL means a large EVAP leak was detected. Whether you have the 3.6L Pentastar, 2.0L turbo, or even the 4xe plug-in hybrid, the gas cap is the first thing to check.
Clues
- Check engine light on
- P0455 stored in PCM
- Fuel odor possible
- Gas cap loose or dirty
Causes by Likelihood
- Gas Cap Seal (Very High Likelihood): Trail dust and debris contamination. $0–$25.
- EVAP Canister Vent Valve (Medium Likelihood): FCA vent valve failure. $150–$300 installed.
- Purge Solenoid (Medium Likelihood): Stuck open. $140–$280 installed.
- Vapor Line (Low-Medium Likelihood): Underbody damage from off-road use. $100–$250.
- Charcoal Canister (Low Likelihood): Water intrusion from fording. $200–$400 installed.
Off-Road Factor
Wranglers see more EVAP issues than typical vehicles due to off-road exposure. Dust, mud, and water can contaminate the gas cap seal and EVAP components. Clean the gas cap area regularly.
Warranty
Your 2022 Wrangler may still be under the 3-year/36,000-mile warranty. Federal emissions warranty (8yr/80k) covers EVAP through 2030.
Safe to Drive?
Yes. P0455 doesn't affect the engine, transmission, 4WD, or any off-road capability.
