    The PO521 engine code is on. Engine oil pressure Sensor/Switch Circuit Range Performance. Will just changing the sensor fix the problem? Or is it something more?

    Its possible the sensor is bad, I've heard of them going bad before.

    Also check the wires going to the sensor, make sure nothing in damaged.
