Felix. Posted March 11, 2021 Share Posted March 11, 2021 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 Quote Link to comment Share on other sites More sharing options...
