Product Details

The Gates Vapor Canister Purge Solenoid line is focused on restoring proper evaporative emission control operation after a failed purge valve, sticking solenoid, or electrical fault. Gates PV397 is engineered as a direct replacement for the original purge solenoid used across many 2006-2016 GM platforms, including Buick Verano, Chevrolet Express 1500, and Cadillac DTS applications. This part cross-references GM OE number 12592015 for the same application.

When the purge solenoid is functioning correctly, fuel vapors are routed through the EVAP system as commanded by the engine control module. A worn or malfunctioning unit can disrupt that process and trigger drivability or emissions concerns. Gates PV397 is built to return the system to proper operation with the correct connector style, terminal layout, and hose-port configuration.

Common Issues This Part May Resolve

• Check engine light related to EVAP purge performance
• Rough idle caused by a purge valve stuck open
• Hard starting after refueling
• Fuel vapor leakage from a failing purge solenoid
• Emissions test failure tied to EVAP system faults

Installation Notes and Tips

Verify connector shape, terminal count, hose-port layout, and outside diameter measurements before installation. Confirm the vehicle’s EVAP routing and compare the original unit to Gates PV397 before replacing the part. After installation, clear diagnostic trouble codes and recheck for EVAP-related faults.
