What You Need to Know About the P0462 Code on Your Dodge Charger

AvatarByCarl Frisch

The P0462 code is an error code that is generated by the Dodge Charger’s on-board diagnostics system when it detects a problem with the vehicle’s fuel level sensor circuit. This code is set when the fuel level sensor circuit’s output voltage is not within the predetermined range. Generally, this issue is caused by a faulty fuel level sensor or its wiring, or the vehicle’s computer may be malfunctioning.

To fix this issue, you should first inspect and test the fuel level sensor for any signs of damage or corrosion. If it appears to be functioning properly, then you should check the wiring and connectors that are connected to it for any signs of damage or loose connections. You should also test the voltage output of the fuel level sensor to ensure that it is within its operating range. If all these tests pass, then you should have your vehicle’s computer scanned for any codes that might be present that are related to this issue. Finally, if all these tests fail, then you may need to replace your fuel level sensor in order to resolve this problem.
