Default 2 Faults on a Focus RS

Hi Guys,

Got a 03 Focus RS and have to issues with it. Firstly, when driving really slow, i.e behind a lorry for a length of time my car throws up a fault code. on my scan gauge it reads P0420 but in the manual it doesn't show up as a fault code. Any ideas? have a sport cat so not sure if it could be anything to do with that

On the flip side, when driving progressively after about 5 minutes of hard driving a warning lights comes on which in the hand book suggests its an automatic transmission light. However the gearbox doesn't feel any different and doesn't give off any extra heat. So was just wondering what it could be, any suggestion on how to check the oil level of the box or anything would be great.

Cheers in advance

Brendan

The code is because of the sports cat.

Do you have a map on the car?
