2025 Chevrolet Traverse Review: Prices, Specs, and Photos

Chevy Traverse P0480: Meaning, Causes & Diagnosis | Drivetrain Resource

This 2018 Chevy Traverse has a check engine light indicating code P0455, which means a large EVAP leak. I initially checked for obvious leaks but found none, so I used a smoke machine to detect emissions leaks. I didn't see any leaks up front, but I found a big leak in the rear of the vehicle right by the gas cap, suggesting a possible issue with the charcoal canister or an emission line. I'll need to raise the vehicle to investigate further, as something may have struck it on the road. At least
