P0462, P0463 FUEL LEVEL SENSOR
Description
INFOID:0000000007462815
The fuel level sensor is mounted in the fuel level sensor unit.
The sensor detects a fuel level in the fuel tank and tr
ansmits a signal to the “unified meter and A/C amp.”. The
“unified meter and A/C amp.” sends the fuel level sens
or signal to the ECM via the CAN communication line.
It consists of two parts, one is mechanical float and the ot
her is variable resistor. Fuel level sensor output volt-
age changes depending on the movement of
the fuel mechanical float.
