Got In My Truck This Morning And Noticed Check Engine light was on. Throwing a Code Of 0455. Anyone know what this code is. Thanks in advance.

Let me google that for you......

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms
You likely won't notice any drivability problems.

Causes
A code p0455 most likely means one or more of the following has happened:

A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
Other leak or damaged piece in EVAP system
Possible Solutions
With a p0455, the most common repair is to:

Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, and/or
Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

Tighten your gas cap. Bet that fixes it

No prob. If the cap is a lil loose or x-threaded or the seal is cracked it will toss a code.
You get gas recently?

I ha this code on my 01 xj and got a new OEM cap and it cleared it right up. Sometimes with our older vehicles its sometimes better to replace or make better when possible
