DTC P0462: Fuel Level Sensor Circuit Low Input
M11310100235USA0000010000
TECHNICAL DESCRIPTION
⦆
The fuel level sensor converts the rest of the fuel to
a voltage and sends it to the combination meter.
⦆
The combination meter sends the data regarding
the rest of the fuel to the ECM.
⦆
The ECM checks whether this data is within a
specified range.
DESCRIPTIONS OF MONITOR METHODS
A short circuit is detected while monitoring the fuel
level sensor output.
