P2065Fuel Level Sensor 'B' Circuit

P2065 indicates that the powertrain control module (PCM) has detected an abnormal condition on the electrical circuit for fuel level sensor 'B', which is typically the secondary fuel level sender in a dual-tank or saddle-tank system. The PCM monitors the sensor's signal voltage and sets this code when the reading falls outside the expected range or is inconsistent with the other fuel level sensor.
