Hey guys,
So the last couple days, my Disco has been throwing P0462 randomly. It seems to only do it on cold starts. The code translates to something to do with low voltage on the fuel sensor... any ideas what could be causing this?

 

How much fuel is in your tank? Low fuel can cause this code!

 

P0462refers to 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 or PCM. 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.


Causes Possible causes : Fuel level sensor circuit harness or connectors is open or shorted - Fuel level sensor may be faulty The Error code is generally activated on detection of the following conditions: An excessively low voltage is sent from the sensor is sent to ECM, low fuel.

Possible Solutions: check plug connection, check wiring Replaced fuel level sensor.

 

Thanks silver. She's got a full tank at the moment, so it's not low... haha is this plug under the rear carpet where the fuel pump is? I might take a looksey...
