A Catalytic Converter (Cat) is an emissions control device that reduces the level of harmful exhaust gasses that enter the atmosphere. It works by converting exhaust emissions into less harmful ones when the gasses pass through it, triggering a chemical reaction. A vehicle will fail an emissions test on either, or all, of the following factors. CO Failure can mean several things, but is most likely caused by a poorly running vehicle. If a Cat becomes contaminated with unburned fuel, it will become unable to effectively convert the gasses that pass through it. A new Cat at full capacity will almost certainly lead to a MOT pass, but unless the fault is rectified, the customer will return the next year complaining of the same problem. HC Failure is an indicator that the vehicle is over-fuelling. A vehicle will fail on this reading if it has HCs in excess of 200ppm. HCs in excess of 60ppm indicates a vehicle problem that needs rectifying as soon as possible. Lambda Failure means there is a problem with the air:fuel ratio on the vehicle. If the lambda reading is less than 0.97, the vehicle is running too rich. If the lambda reading is greater than 1.03, the vehicle is running too lean.
