When Code 32 appears, you may experience:

  • Check Engine Light illumination
  • Rough idle or stalling
  • Decreased fuel efficiency
  • Engine pinging or knocking
  • Failed emissions test

Diagnosing Code 32

To diagnose the issue:

  • Inspect EGR valve and passages for carbon buildup
  • Check vacuum lines for leaks or damage
  • Test EGR temperature sensor functionality
  • Verify EGR solenoid operation
