Common Repair Symptoms

• Incorrect vacuum routing in the EGR or emissions circuit
• Rough idle caused by a faulty vacuum switch
• Emission-system malfunction on temperature-sensitive vacuum controls
• Vacuum leaks at the switch body or hose connections
• Hard-to-diagnose drivability issues tied to thermal vacuum switching

Installation Notes and Tips

• Verify the thread size and hose connector layout before installation.
• Inspect vacuum hoses for cracks, hardening, or loose fitment before replacing the switch.
• Confirm the vehicle’s emissions configuration and model-year application against the fitment list.
• Use the OE reference and part number PVS85 to match the correct replacement.
