I have am 01 Hyundai elantra that is giving a code of PO501 "A Range" the speed odometer quits working and mileage stops to when it does that. We can b driving it and it will go bk to idle from 55mpg like as if has died. But tale ur foot off the pedal and press it again immediately it just goes on like nothing has happened. But it's also giving a few other codes like O2 sensor and manifold absolute pressure.y question is where is this sensor located being as it has 2 others of which we change both of them and it us worse than ever with throwing this fit.
