P0501 would be a right front wheel speed sensor fault. Either a bad sensor or the circuit to it is open. If you have a multimeter, you can test the sensor and harness from the connector on the ABS module and PCM. You would go to pin 39 in the PCM connector 138 and pin 9 in E39 on the ABS connector. There should be continuity, if not then you unplug the speed sensor and short the two pins, if you now see continuity the harness is okay and it's likely a bad sensor.
