My girlfriend has a 2013 Elantra gls. I have read some other threads but can't seem to find a good answer or solution. Today, after starting the car, noticed that the speedometer, odometer, gas gauge, rpms are all not working. They all light up but nothing works. The only thing that is reading is the Temp Gauge. Check engine light came on and got a P0462 (fuel level A sensor circuit low input). I disconnected the battery, checked fuses, flipped I/P switch on and off. Still nothing. Would a fuel sensor cause the gauges to not work? To me, I am thinking the check engine light came on because the gauges aren't working so the car thinks the fuel sensor isn't working too??? This all happened out of no where, no signs of anything.
