Mybootdontopen Posted January 21, 2011 Report Share Posted January 21, 2011 (edited) May have asked this before but car failed its MOT a while ago due to emissions but managed to get a MOT off another garage somehow! Anyway i want it rectifying so putting it in for a check to see how much it will cost to fix. The readings that failed were: Fast Idle Test: CO Max limit: 0.300 Actual value: 0.686 Lambda max limit 1.030 Actual value: 1.048 Second Fast Ilde Test: Lamdba Max Limit: 1.030 Actual Value: 1.033 Means nothing to me but obviously the CO reading is way out, will that and the Lambda setting be related or completely different Should i be expecting a big bill do you think?

wolverine1984 Posted January 21, 2011 Report Share Posted January 21, 2011 might be nothing wrong at all, did the car have a good 'thrashing' before testing as the Cats only work properly when fully warmed up Link to comment Share on other sites More sharing options...
Mybootdontopen Posted January 21, 2011 Author Report Share Posted January 21, 2011 Yeah oil temp was 78 degrees Link to comment Share on other sites More sharing options...
princy Posted January 21, 2011 Report Share Posted January 21, 2011 If your lambda's not working properly for any reason it'll also throw your CO out, take it off and give it a good clean, could be carboned up Link to comment Share on other sites More sharing options...
shadow750 Posted January 21, 2011 Report Share Posted January 21, 2011 (edited) Oil temp makes no odds. Its the temp of the cat that matters its got to be bloody hot before its starts to work. So a good thrash wont do it if its gonna sit there for 20 mins before the test. The lambda can be a blow on the exhaust or the lambda sensor at fault. You can take it out an clean it also a common fault with lambda sensors it a bab earth wire so check the plug termanals are clean. Also loooking at those readings there from the fast pass test. After the first test the tester should do a longer warm up test this also gives a more accurate reading for the type of car on test in other words it alters the values in the gas tester to meet with your celica wich could be higher than that of the fast pass test. Other thing that can cause high co readings are, poor oil, dirty air filter, oil in the cat, Cat may be past its best, (Bad plugs, leads ets cause high HC levels due to unburnt fuel. Hope this helps. Chris I must say the tester needs to input the correct engine type 3sge etc to get it right. Edited January 21, 2011 by shadow750 Link to comment Share on other sites More sharing options...
Mybootdontopen Posted January 21, 2011 Author Report Share Posted January 21, 2011 I wouldnt have a clue where the lambda is or what it is lol My throttle body has a lot of carbon build up in it if that affects anything? Link to comment Share on other sites More sharing options...
Alan Clogwyn Posted January 23, 2011 Report Share Posted January 23, 2011 That is lean according to the lambda reading, so could be a hole in the exhaust sucking in fresh air, but Co being high points to a Cat problem. So could well be both. Link to comment Share on other sites More sharing options...
