2005 Focus EMG on but not DTC code, help!!

FUNKYDADDIO

Hi Guys, My 2005 focus engine management light has come on but when I do the self test it registers none under DTC so no fault found. Is there a fuse I can take out to reset and see it if fixes it? Had read about an EEC/ECC fuse on older models which would do this but cant find it in mine. Also no noticeable performace change when driving although I had a flexi fitted on my exhaust last week. Any help greatly appreciated, thanks..

The self test is not designed for reading all engine codes.. It shows a very small handful of codes if your lucky.

You need a proper OBDII code reader to read the codes.

These can be bought for £10 upwards and worth buying.
