thanks for replying,i do have a scanner and reset the light but comes back on about a minute after running,the car is fantastic and does not miss a beat so i am thinking nothing serious but MOT is due soon and is a failure with that light on.

hi there i am new to this club and need help with my 2002 xj8,the check engine light is on (yellow) so i put it in for a diagnostics check and came back as faulty o2 sensors.as the engine is running absolutely sweet as a nut with no heavy MPG the mechanic said the sensors can not be faulty.can anybody offer any advice?
