P0464
COMPONENT DESCRIPTION
The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the ECM.
It consists of two parts, one is mechanical float and the other side is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.
ON BOARD DIAGNOSTIC LOGIC
ECM receives two signals from the fuel level sensor. One is between the level sensor and the combination meter, and the other is between the level sensor and the ground. This diagnosis indicates the former to detect open or short circuit malfunction.
DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE
NOTE: If "DTC CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.
TESTING CONDITIONS: Before performing the following procedure, confirm that battery voltage is more than 11V at ignition switch "ON ".
