EGR Vacuum Regulator Solenoid Circuit Malfunction

2008-2012 Ford Escape 3.0L V6 Duratec

Moderate SeverityPowertrain

Description

The EGR Vacuum Regulator (EVR) solenoid circuit has a malfunction. This solenoid controls vacuum to the EGR valve. When it fails, EGR valve operation is impaired.

Symptoms

  • Check Engine Light
  • EGR valve stuck open or closed
  • Rough idle (if stuck open)
  • Knocking/pinging (if stuck closed)
  • Failed emissions

Common Causes

  • Faulty EVR solenoid
  • Wiring issue to EVR solenoid
  • Clogged vacuum lines to EGR valve
  • PCM driver failure

Diagnostic Steps

  1. Test EVR solenoid resistance (typically 26-40 ohms)
  2. Check wiring and connector
  3. Inspect vacuum lines
  4. Command solenoid with scan tool and verify operation

Repair Notes

Replace EVR solenoid if faulty. Repair vacuum lines. Check wiring.
