Code P0462 2006 Infiniti G35 Description

The P0462 diagnostic trouble code (DTC) indicates that there is a low input signal from the fuel level sensor circuit in a 2006 Infiniti G35. The fuel level sensor is responsible for measuring the amount of fuel in the tank and sending this information to the vehicle's engine control module (ECM). When the ECM receives a low input signal from the sensor, it may not accurately display the fuel level on the dashboard or could cause the fuel gauge to fluctuate erratically. This can lead to inaccurate readings, which may result in running out of fuel unexpectedly or not knowing when to refuel.
