P0462 Fuel Level Sensor A Circuit Low
Fuel-level sensor A below lower plausibility — short to ground. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
Is it safe to drive with P0462?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
