P2383: Exhaust Gas Recirculation Sensor D Circuit Range/Performance
What to do
Soot fouling is this family's ageing mode — ask whether cleaning is an option before a replacement is priced, and expect the answer to depend on which sensor D actually is on this engine.
What this code means
EGR sensor D's reading is alive but implausible — and on EGR sensing, implausible has a characteristic mechanism: soot. These sensors live in exhaust gas by design, deposits build on elements and around position sensors' moving parts, and readings drift or stick long before anything fails electrically. A cleaning is a legitimate repair in this family, and a sensor condemned without the deposits being looked at is the familiar economy of replacing the messenger.
Likely causes
Start here
- Faulty EGR position sensor · moderate
- Sensor drifted out of calibration · moderate
Less common
- Corroded or loose connector · easy

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
