What does code P2268 mean?

Q: What does code P2268 mean?

Water in Fuel Sensor Circuit Intermittent. P2268 means the engine control module (ECM) has detected an intermittent electrical fault in the water-in-fuel sensor circuit, typically a signal that cuts in and out rather than failing completely. The ECM monitors the sensor's voltage or resistance and flags this code when the reading momentarily drops out or spikes outside the expected range for a fraction of a second.
