What does code P2386 mean?

Q: What does code P2386 mean?

EGR Sensor E Circuit High. P2386 indicates that the powertrain control module has detected an abnormally high voltage on the signal circuit for EGR Sensor E, which is typically the EGR cooler outlet temperature sensor on engines with a cooled exhaust gas recirculation system. The computer expects the sensor's signal voltage to stay within a calibrated range, and a sustained high reading tells it the circuit is open, shorted to voltage, or the sensor has failed.
