Code p0462 is low voltage on fuel level sensor possible causes are fuel was low more more likely is you filled up while car was running this is a common problem sometimes setting this code. you can check the seal around the gas cap and make sure there are no cuts and its sealing good. i hope this helps
Relates to fuel level sensor in fuel tank.if im not mistaken this is an indication of voltage output from sensor abnormally low.hows your gas gauge been woking lately?
