Mark1eboy Posted January 28, 2014 Share Posted January 28, 2014 Hi can anyone help. I've a 2003 focus st170. The engine management light has come on. I've done a self diagnostic and it's coming up with no dtc codes. Can anyone help? Quote Link to comment Share on other sites More sharing options...
Mr Singh Posted January 28, 2014 Share Posted January 28, 2014 have it plugged in to a diagnostic machine and it should give you a code Quote Link to comment Share on other sites More sharing options...
Mark1eboy Posted January 28, 2014 Author Share Posted January 28, 2014 I have and it's coming up as an emissions sensor. Not sure if it EGR valve or the sensor near the cat. But I thought the car would have diagnosed a fault code on its own that way I would know which sensor it was. Quote Link to comment Share on other sites More sharing options...

Mark1eboy Posted January 29, 2014 Author Share Posted January 29, 2014 I think so but apparently there's 2 sensors Quote Link to comment Share on other sites More sharing options...
Mark1eboy Posted January 31, 2014 Author Share Posted January 31, 2014 It is the lambada sensor. How easy is it to sort and what do they cost?? Quote Link to comment Share on other sites More sharing options...
