How to service and repair the catalytic converter on Ford Focus?

Beginning the repair work on a catalytic converter requires suspending the vehicle at an elevated height. The removal process starts with unstowing the rear catalyst monitor sensor by unplugging its electrical connection before taking out the sensor. Service on the catalytic converter begins with disconnecting the unit followed by removing its support bracket then lowering the vehicle into position. Start by detaching high-pressure line retaining clips and then remove exhaust manifold heat shield. The front catalyst monitor sensor becomes disconnected when you take out its electrical connector and pull off the sensor. Begin by unwiring the EGR tube by taking out its bolt and tube followed by unfastening the catalytic converter and rejecting the installation nuts. After raising the vehicle again enable support to the catalytic converter before taking off the bracket for support. The technician should disconnect and discard the catalytic converter together with its front strap and all gaskets should be disposed. To install the components start by relaxing the rear support bracket bolts before the bracket faces can touch. This will enable bracket movement. Fit a new gasket and install the catalytic converter by applying the nuts but keep them slightly loose. The flexible pipe and new gasket should be used to make a loose attachment between the catalytic converter. Fasten the rear catalyst monitor sensor while also linking its electrical cable. The vehicle should be lowered during installation when tightening the nuts before attaching the front catalyst monitor sensor and its connector. Place back the exhaust manifold heat shield while securing both the high-pressure line. After raising and supporting the vehicle once more you should remove the nut then put in the front bracket before tightening its bolts. The lower support bracket should be fitted loosely before using new nuts to mount it followed by bolt tightening then lowering the vehicle.

Catalytic Converter is used in exhaust and emissions systems of Ford Focus cars by converting toxic exhaust emissions into less toxic ones before they can be released into the environment. Mainly it converts CO, HC and NOx into water, carbon-di-oxide and nitrogen through chemical alteration using means such as platinum, palladium and rhodium. Several generations of Ford Focus vehicles have been fitted with a two-way and even three-way catalytic converter. Earlier, two-way converters were simply aimed at oxidizing CO and HC, subsequent three-way converters also minimized NOx emissions. High flow performance catalytic converters are on the market for the increased flow as to add to the abilities of the engine while still maintaining the needed levels of efficiency for the catalyst. These converters can be of direct-fit or universal type, where the direct-fit converters require that they be bolted in, while the universal converters require some modifications to be made before installation.
