Engine warning light has come on which showed a P0420 error code

 

Placed this on a OBD scanner which gave the following results.  Taken from a coldish engine:

 

Oxygen sensor 1 Bank 1 Voltage - 0.16V

Oxygen sensor 1 Bank 1 Short term fuel trim - 3.13%

Oxygen sensor 2 Bank 1 Voltage - 0.48V

Oxygen sensor 2 Bank 1 Short term fuel trim - n/a%

 

The "n/a%" never changes as I rev the engine, where as the other values do fluctuate

Is this normal - or does it appear that one of the sensors has stopped working
