This part cross-references Dorman - OE Solutions 911-112 for the same application.

What It Helps Fix

• Check engine light related to evaporative emissions faults
• Rough idle or drivability issues caused by purge flow problems
• Fuel vapor routing concerns in the EVAP system
• Failed purge solenoid electrical operation
• Emission test failures tied to purge circuit malfunction

Installation Notes and Tips

Verify connector style, port layout, and vehicle fitment before installation. This part uses a female connector, one oval connector shape, two ports, and male blade terminals, so matching the original configuration is important. Confirm the exact application for your Ford Mustang, Ford Explorer, or Mercury vehicle using the year and notes listed in fitment data, especially where harness or sensor notes are specified.

For best results, inspect vacuum lines, electrical terminals, and nearby EVAP components during replacement. Standard Ignition CP403 is intended as an OE-style service replacement for vehicles listed in the fitment table.

Quality Assurance

Standard Ignition states that its canister purge valves are manufactured to meet or exceed original equipment specifications and are tested at the end of the line before release. The use of high-grade materials supports long service life and stable performance in emission control service.
