P1464 INFINITI, NISSAN: FUEL LEVEL SENSOR
The Fuel Level Sensor (FLS) is an electronic device whose function is to detect the fuel level present in the fuel tank. Subsequently, this information is transmitted to the ECM (Engine Control Module) through an electrical signal, which, based on this, will inform the driver through the corresponding indicators.
The Fuel Level Sensor is composed of two parts, one is a mechanical float and the other is a variable resistor. The output voltage of this sensor changes according to the movement of the mechanical fuel float. If the ECM receives a voltage from this sensor, which exceeds the maximum allowable level, the P1464 OBDII fault code will be set on Infiniti and Nissan vehicles.
P1464 OBD2 diagnostic code is set for one of the following reasons:
The steps to follow to troubleshoot the DTC P1464 OBDII code are as follows:
