Aldo Posted July 20, 2009 Share Posted July 20, 2009 Just had my MOT done on a 1.8i ford focus 2002 reg with 80,000 miles. It passed :-) What I am struggling to understand is the following (I have looked for this info everywhere but can't find it) MOT print out is : FAST IDLE TEST PASS ITEM ........................... ACTUAL ....................................LIMIT RPM .....................................M.CHECK ...............................2500 - 3000 CO......................................0.00 % ....................................0.20 MAX HC........................................1 PPM ..................................... 200 MAX LAMBDA .................................1.00 .......................................0.97 - 1.03 NATURAL IDLE TEST ITEM .........................ACTUAL .......................[u]LIMIT RPM.................................M.CHECK...........................450 - 1500 CO..................................0.00 %......................................0.30% Does this mean the car is producing no CO2 or am I just reading it wrong ?

w2575 Posted July 21, 2009 Share Posted July 21, 2009 Looks as if the only reading is from the lamda sensor ! most likely the probe thats placed in your exhaust was not working properly !!!!!! If its a hydrocarbon burning machine it must produce co2 !!!!!! cars rarely fail emissions anyway ! Quote Link to comment Share on other sites More sharing options...
Aldo Posted July 21, 2009 Author Share Posted July 21, 2009 Makes sence now. I just could not understand why readings where so low. Thanks for the explanation :) Quote Link to comment Share on other sites More sharing options...
fordtech Posted July 29, 2009 Share Posted July 29, 2009 The mot doesn't check co2 , only co , which should be as close to 0 as posible due to the catalytic converter fitter to the vehicle! Quote Link to comment Share on other sites More sharing options...
