i just fitted this to my 172 its a mk1 with 2 sensors but the emissions light came on straight away, anybody know why and does this mean it wont pass a cat or emissions test

dont know mate but did u notice any difference in the car after fitting it performance wise? i fitted one on my old clio 16v and didnt notice a thing, apart from a lighter wallet

The mk1 only has 1 sensor IIRC something isnt right there!! The mk2 has 2 sensors, this will sound daft, but have you blocked up the other hole???

The mk1 has the sensor before the CAT, but the mk2 has an additional sensor after the CAT i think, cant remember exactly

(FRED on Roamers computer)

This is actually roamer

Ok, so your mk1 172 is one of the ones with 2 lambda sensors..... ok

and you have bought the sports cat, NOT the 172 de-cat pipe yes?

well if that is correct then 1st thing monday ring David, because it should go on without a problem and as far as I know there should be no trouble at all.

 

[JAY172]

keep us posted because im thinking of buying one of those cats as well.

its a late mk1 with 2 sensors i havent had chance to use the car yet but ill let you know later in the week if its made any difference.If the emissions light is on i might as well have just fitted the de cat though

But the mk1 172 only has one lambda sensor?!



Is this a pukka UK car or a euro import???

What age is the car?

 

[rt172]

Early mk1s only had one lambda, later ones (without the gear change light) had 2 sensors.

recheck the oxygen sensor connectors there might be a bad connection since they were plugged on and off.if the light come on straight away then its most likely a connection fault.the ecu wont have had enough time to self test the cat yet.

 

[Kevins172]

the car is march 2001 , the connections are both okay

 

[JAY172]

have you had the emissions checked to make sure there still ok and the cat is working.

 

[Kevins172]

not yet i only fitted it on saturday im going to ring k-tec tomorrow

 

[JAY172]

let me know what they say,cheers

Mk1 only has one sensor (at least I never seen a mk1 with two) I have one of the latest mk1´s and of course I have the Rsport sportscat also used on Cliocup racers. Stock there are two single cats and the sensor is located before the cats. The cat I have now is a single stainless one looks just like a muffler. The lights which came on could be a wrongly mounted sensor. Did you tighten the thing and maybe use a new one and see if the sensor is still ok.



Good luck...

Does it make a difference?

Is there more power for those that have fitted it?
