Dorman 911-385 is engineered to match the original purge valve layout so the evaporative emissions system can control fuel vapor flow from the charcoal canister to the engine. This part is a practical OE-style replacement for Chevrolet C1500 and GMC Yukon service, as well as other listed GM trucks, vans, and SUVs from 1996-1997. This part cross-references Standard Ignition CP225 for the same application.

What It Helps Fix

• Check engine light related to EVAP purge performance
• Fuel vapor leakage from a worn or sticking purge valve
• Rough idle or drivability issues caused by incorrect vapor flow
• Failed emissions inspection tied to evaporative system faults
• Hard starting after refueling when purge control is not operating correctly

Installation Notes

Use the existing electrical connector and hose routing as a reference during replacement. Verify the connector shape, port sizes, and mount hole spacing against the original valve before installation. On 1997 Chevrolet P30 applications, confirm the 2-blade terminal requirement noted in the fitment data before ordering.

Quality Assurance

Dorman designs this purge valve as a direct-fit replacement for the original equipment part and builds it to support evaporative emissions system function and regulatory requirements. Interchange references include 2N1035, 1997258, CP207, PV144, and Standard Ignition CP225.
