Q: What does code P2389 mean?

EGR Sensor E Circuit Intermittent. P2389 indicates that the powertrain control module has detected an intermittent fault in the electrical circuit for the EGR sensor, which is typically a position sensor integrated into the exhaust gas recirculation valve. The computer monitors the sensor signal for expected voltage or resistance ranges and flags this code when the signal momentarily drops out or jumps outside normal limits.
