bradwebb Posted March 27, 2010 Share Posted March 27, 2010 Hi Guys, New to the forum Basically, my dads 2001 1.6 Zetec Focus engine management light came on 4 years ago. He took it to a garage which diagnosed the fault as catalytic converter and replaced it. 4 weeks after the light came back on, but my dad stupidly ignored it Every year since, my dad has paid £300-400 for a new catalytic converter for the annual mot (light still stays on) He has just paid for his 4th which is a joke Any ideas what could be the problem Quote Link to comment Share on other sites More sharing options...
mintalkin Posted March 27, 2010 Share Posted March 27, 2010 sounds like you could have a faulty oxygen sensor, try and get the codes from the ecu. Quote Link to comment Share on other sites More sharing options...
bottletree Posted March 27, 2010 Share Posted March 27, 2010 Could also be something as simple as static on a sensor. Which means there is no problem at all.£400 a year to replace the cat. Surely if its a part fault then the warranty should cover it? Quote Link to comment Share on other sites More sharing options...
