Fuel Level Sensor A Circuit Low Input

The fls converts the mechanical fuel level into an electrical signal for the powertrain control module pcm.

Fuel level sensor a circuit low input.

P0462 is a diagnostic trouble code dtc for fuel level sensor circuit low input. Obd ii fault code p0462 is defined as fuel level sensor circuit low input and is set when the pcm powertrain control module or bcm body control module on some applications detects a signal from the fuel level sender unit that indicates a fuel level that exceeds the fuel tank s capacity. The fuel level sensor fls is usually found mounted in the fuel tank usually in the top of the fuel tank fuel pump module. The sensor detects a fuel level in the fuel tank and transmits a signal to the engine control module ecm.

This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. This code is a generic trouble code meaning it applies to all vehicles equipped with obd ii especially those made from 1996 up to the present. Error code p0462 is defined as fuel level sensor circuit low input which means the fuel level sensor is no longer taking correct readings. The fuel level sensor consists of two parts one is mechanical float and the other side is variable resistor.

Our certified mobile mechanics can come to your home or office to perform the check engine light is on diagnostic inspection. When the powertrain control module pcm gets an input signal from the fuel gauge or fuel level sensor that is higher than the actual level of fuel in the gas tank it will store a p0463 code and the check engine light will turn on. The fuel level sensor output voltage changes depending on the movement of the fuel mechanical float. The sensor detects a fuel level in the fuel tank and transmits a signal to the powertrain control module pcm.

Typically the pcm will then inform other controllers utilizing the vehicle s data communication bus.
