What does code P0A38 mean?

Q: What does code P0A38 mean?

Generator Temperature Sensor Circuit Low. P0A38 indicates that the generator temperature sensor circuit is reporting a voltage below the normal range, which the powertrain control module interprets as an excessively low signal. The computer has detected that the sensor's output is lower than expected for the current operating conditions, often indicating a short to ground or a failed sensor.
