What does code P1464 mean?

Q: What does code P1464 mean?

Fuel Level Sensor Circuit Ground Signal. P1464 on Nissan vehicles means the engine control module (ECM) has detected an abnormal ground signal on the fuel level sensor circuit, so it cannot reliably determine how much fuel is in the tank. The ECM monitors the return path from the fuel level sending unit and flags this code when the voltage on that ground circuit stays outside the expected range.
