Detailed Product Information

This ported vacuum switch is designed for vehicles that rely on temperature-sensitive vacuum signal control for EGR and related emission functions. Standard Ignition PVS133 is engineered to maintain consistent routing behavior under heat exposure, with component materials selected for durability in underhood conditions. It is a direct-fit style replacement for select 1980 Buick LeSabre, Riviera, 1980 Oldsmobile 98, Custom Cruiser, Delta 88, Toronado, and 1980 Pontiac Bonneville and Catalina, plus 1985-1986 Chevrolet Chevette and Pontiac T1000 models.

This part cross-references Bosch 13025 for the same application.

Common Symptoms It Can Address

• Incorrect vacuum switching in the EGR circuit
• Emission system fault codes related to vacuum control
• Rough idle or drivability issues tied to vacuum routing
• Vacuum leaks at a worn switch body or connector
• Delayed or inconsistent thermal vacuum response

Installation Notes and Tips

Verify the vehicle’s port count, connector style, and color match before installation. This PVS133 uses 3 hose connectors and push-on connections, so the vacuum hoses should seat fully and route exactly as removed from the original switch. Confirm the application against the vehicle’s emission layout, especially on 1980 Buick, Oldsmobile, and Pontiac models and 1985-1986 Chevrolet Chevette and Pontiac T1000 vehicles.

Quality Assurance
