Detailed Description

Standard Ignition CP425 is a vapor canister purge solenoid used to control fuel vapor flow from the charcoal canister into the engine intake under the proper operating conditions.

The part number CP425 is a practical OE-style replacement when the original purge valve is no longer sealing or responding correctly.

This part cross-references Dorman OE Solutions 911-017 for the same application. Standard Ignition CP425 is also referenced by several other aftermarket numbers used in the same GM fitments.

What It Helps Fix

  • Check engine light related to evaporative emissions faults

  • Fuel vapor purge flow problems
  • Rough idle caused by purge valve leakage
  • Failed emissions inspection tied to EVAP system codes

Installation Notes and Tips

Verify connector style, port layout, and bracket mounting points before installation. This purge solenoid uses a female oval connector with male pin terminals, so matching the electrical connection and hose routing is important for proper fitment. Confirm vehicle application by year, make, and model before replacing the original unit.
