sy8ts Posted January 18, 2015 Share Posted January 18, 2015 Bloody hell!!! Jacked the car up today and had a look, somebody has actually snipped the wires!!!!!! Both sides,!, don't know how long it's been like this as it been off the road for a few years and been in storage, Why the hell would anybody do that? It's surely been like that since I bought it, I bought the car tested in 2010 with mot, moved away n stored the car I a secure warehouse, so wasn't done there, Laugh is I just had it tested and it sailed through as the emissions machine was broke that day, I'm a bit concerned now though as this could have been done for god knows what reason , on the plus side, it doesn't use oil, water or anything else and is low miles, just can't understand why 1 somebody would do this & 2nd what effect it's had, Quote Link to comment Share on other sites More sharing options...
Toon Chris Posted January 18, 2015 Share Posted January 18, 2015 Not sure how the ecu reacts with no signal, I presume it uses a standard map, but more to the point I assume it stops the CEL from coming on? In which case if they were snipped its easier to sell the car as no warning lights coming up. Decent Lambdas are about £100 Quote Link to comment Share on other sites More sharing options...
sy8ts Posted January 18, 2015 Author Share Posted January 18, 2015 CEL light is on, that's how I discovered they were snipped. Plugged in my lap top & read code P0037. Is that £100 each? Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 18, 2015 Share Posted January 18, 2015 Which ones have been cut, the front or rear cat sensors? if its the rear cat sensors it wont effect the running, I would suspect the either they when faulty or the cats are going and it threw a CEL, so they cut them hoping that it would cancel the CEL derrr!

Toon Chris Posted January 19, 2015 Share Posted January 19, 2015 And you passed the MOT with CEL lights on? Fronts are a little cheaper but backs are more precise and more costly. Most likely its what Ricky said and they cut them hoping to stop the CEL. That code is a bank 1 sensor 2 heater element so that's the nearside rear I believe. The trouble is that lambda codes can be the symptom of a problem elsewhere so first things first roughly wire them back in and try again. And then try cross-wiring them. If you get the same error but for the other bank then you know the lambda probably is the issue after all. If you need some replacement that Clarke Motorsports are a good choice as they understand that the front and back lambdas are not the same.

Tricky-Ricky Posted January 19, 2015 Share Posted January 19, 2015 Sorry but thats incorrect, the cat monitor lambdas are exactly the same apart from there response time is much slower than the ones used for O2 feedback to the ECU to control fuelling, the cat O2 are not used.

sy8ts Posted January 20, 2015 Author Share Posted January 20, 2015 Its both the rears/post cat, cut flush at the sensor & multi plug, is that Clark motorsport in Kintore/Aberdeen? I can get the light to switch off with my code reader & stays off for a day or too, passed the test as the emissions machine boke down mid test,, Quote Link to comment Share on other sites More sharing options...
