What does code P2387 mean?

Q: What does code P2387 mean?

EGR Sensor E Circuit Low. P2387 indicates that the powertrain control module has detected an abnormally low voltage signal on the EGR sensor E circuit, which is typically the sensor that monitors the position of the exhaust gas recirculation valve. The computer expects a voltage within a specific range and sets this code when the signal falls below the minimum threshold for a calibrated time.
