Check Engine Light P0455

Today I show how I read and clear a check engine light on a 98 jeep cherokee. The code is P0455 and is a large evap leak. Most of the time this is just a leaking gas cap caused by not tightening it up all the way or the seals in the cap just drying out. If the code comes right back it may be something more severe in your evap system and all the hoses and the evap canister should be checked.
