Detailed Product Overview

The Standard Ignition CP480 purge solenoid helps control fuel vapor flow from the charcoal canister into the engine intake under the proper operating conditions. This supports stable evaporative emissions system operation and OE-style fitment for vehicles such as the 2005 Buick LaCrosse, 2004-2005 Buick Rendezvous, 2004-2005 Cadillac CTS, 2004-2005 Cadillac SRX, and 2005 Cadillac STS. The CP480 part number is also a useful reference when comparing replacement options for these applications.

This part cross-references Bosch 0280142399 and Dorman - OE Solutions 911-672 for the same application.

What It Helps Address

• Check engine light related to evaporative emissions faults
• Fuel vapor purge flow irregularities
• Hard starting after refueling caused by purge control issues
• Rough idle from a purge solenoid that is not operating correctly
• Emissions test failures tied to purge system performance

Installation Notes and Tips

Verify connector style, hose size, and port layout before installation. The CP480 uses a female 2-connector rectangular interface with male blade terminals, so matching the electrical connection and hose routing is important. Confirm vehicle application by year, make, and model before ordering, especially for Buick LaCrosse, Buick Rendezvous, Cadillac CTS, Cadillac SRX, and Cadillac STS coverage.
