Code P0461 Acura Description

The Fuel Level Sensor (Fuel Gauge Sending Unit) is incorporated into the fuel pump, installed in the fuel tank, and measures the fuel level of the fuel tank. The Powertrain Control Module (PCM) checks the change in the fuel level sensor output and then compares it to the calculated fuel level value. If the absolute difference between the fuel level sensor output changes and the fuel consumption is a specified value for a specified duration when a certain fuel amount is consumed, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
Repeatedly filling the tank with less than the specified amount may lead to a mismatch in the actual fuel amount versus the calculated amount.
