P0462: Fuel Level Sensor 'A' Circuit Low Input
17 vehicles · 8 makes · $120-$1,100 repair
Most Reported On
P0462 is an OBD-II diagnostic trouble code meaning “Fuel Level Sensor 'A' Circuit Low Input.” P0462 indicates the powertrain control module detected a fuel-level sensor signal voltage that is lower than the normal operating range — often interpreted as an empty or near-empty reading that may not reflect the actual fuel amount. The fuel level sender reports tank level via a variable resistance, and an abnormally low signal can stem from a short to ground or a failed sender. This usually shows up as a stuck-low or inaccurate fuel gauge rather than a driving problem. It is low-urgency but should be corrected so the gauge and EVAP monitors work properly. This code is most commonly reported on 2007-2014 GMC Sierra 3500HD, 2005-2009 Nissan Armada, and 2011-2017 Nissan Juke, plus 14 other vehicles, with repair costs ranging from $120 to $1,100.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
