EGR Vacuum Regulator Solenoid Circuit Malfunction

on 2017 Lincoln Continental 3.7L V6 · FWD

What this code means

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.
