Detailed Description

This vapor canister is engineered for evaporative emissions service on 2003-2006 Kia Sorento, 2002-2005 Kia Sedona, and 2000-2002 Kia Sportage with Federal Emissions. The carbon filter element helps capture fuel vapors in the EVAP system so they can be stored and routed properly, supporting emissions control operation. For buyers searching for a Kia Sorento vapor canister, Kia Sedona EVAP canister, or Kia Sportage vapor canister replacement, Dorman 911-257 provides an OE-style solution matched to the original canister form and port layout.

Dorman 911-257 is a practical replacement when the original canister housing or internal filter media has deteriorated. The plastic housing and connector material are selected for evaporative system use, and the 3-port configuration supports the factory routing used on the listed Kia models. This part cross-references Standard Ignition CP3123 for the same application.

What It Helps Fix

• Check engine light related to EVAP system faults
• Fuel vapor storage issues caused by a saturated or damaged canister
• Fuel odor from evaporative system leakage
• Emissions test failures tied to evaporative control problems
• Improper purge or venting behavior in the vapor recovery system
