Exhaust Gas Recirculation Sensor A Circuit

on 1998 Chrysler Voyager 3.3L V6 · AWD

What this code means

There is a fault in the EGR position sensor circuit. This prevents the PCM from knowing how far the EGR valve is open, affecting emissions.

Symptoms

  • Check engine light on
  • Rough idle
  • Failed emissions test

Common causes

  • Faulty EGR position sensor
  • Wiring or connector problems
  • Carbon-clogged EGR valve
  • Bad PCM

Diagnostic steps

  1. Read code and freeze frame data
  2. Inspect EGR sensor wiring and connector
  3. Test sensor voltage and ground
  4. Replace EGR sensor or valve as needed

⚠ STILL BEHIND THE PAYWALL
The 1998 Chrysler Voyager repair data is incomplete because no one has sponsored it yet. For $99, we generate the full step-by-step procedures, then fact-check them with a second AI pass and your expert review. Your name on every procedure, permanently.
The same data would cost $169/mo from Mitchell1 or $30/year from ALLDATAdiy — and you'd be renting access, not freeing it. Sponsor once, free forever.
