P2385 — EGR Sensor E Circuit
A circuit fault is detected on the fifth exhaust-gas recirculation sensor (E). The ECU loses this EGR feedback channel and falls back to a substitute value; emissions and EGR rate accuracy on this stage are reduced until repair.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
