Jimgeriatric Posted December 3, 2015 Share Posted December 3, 2015 Hi all, I last April I had an aftermarket cat fitted to my 2003 Fusion 2, 250 miles ago mil light came on checked code came up with catalitic efficiency low p somthing can't remember however took it to my local garage that fitted it he put it through emissions test it flew through I saw printout then 250 miles plus later light came on again unable to put it on my code reader as I am away on Holliday in Norfol. Has anybody had any experience with this if so what cured problem. Kind regards to all Jim Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted December 3, 2015 Share Posted December 3, 2015 aftermarket parts have issues with OEM sensors. The tolerances and expected behaviours are different and can throw errors. This is most likely the issue you have here. 2 Quote Link to comment Share on other sites More sharing options...
Jimgeriatric Posted December 3, 2015 Author Share Posted December 3, 2015 Hi James, Many thanks for your reply, what you say sounds likely how can I get round this problem as cheaply as possible pensioners are not usually loaded.

jeebowhite Posted December 3, 2015 Share Posted December 3, 2015 Hi Jim, Unfortunately I dont know if cheap is something that can really come into it. I think you may need to get an OEM part, rather than a pattern or aftermarket, you may be able to find a good cat at a breakers yard, but they are hard to come by. 1 Quote Link to comment Share on other sites More sharing options...

Jimgeriatric Posted December 10, 2015 Author Share Posted December 10, 2015 Hi Jason Thinking aloud will taking the lambda sensor bulb out of the exhaust flow stop it doing its job ie cutting down the fuel injector trim causing over fuelling. Hope this makes sense. Regards Jim Quote Link to comment Share on other sites More sharing options...
JMT_1989 Posted December 10, 2015 Share Posted December 10, 2015 The sensor is just there to tell the car if the is an issue with the emissions by fitting the spacer you will be giving the sensor more oxygen so the emissions will register lower so the EML light will not light up Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Jimgeriatric Posted December 10, 2015 Author Share Posted December 10, 2015 Many thanks Jason will do it as soon as I get home from Norfolk. Jim Quote Link to comment Share on other sites More sharing options...
