What does code P25D8 mean?

Q: What does code P25D8 mean?

Fuel Level Sensor C Performance. P25D8 indicates that the powertrain control module (PCM) has detected a performance fault in the fuel level sensor circuit designated as Sensor C, meaning the signal from that sensor does not correlate with expected fuel volume changes or is outside the normal operating range. The PCM monitors the sensor's voltage or resistance over time and flags this code when the readings are erratic, stuck, or implausible given other fuel system data.
