• Q: How to service the catalytic converter on a 2.0L Zetec-E on 2002 Ford Focus?

  A: A service of the catalytic converter for the 2.0L Zetec-E engine starts with vehicle elevation and suspension. You should first remove the rear catalyst monitor sensor by unconnecting its electrical connector and proceeding to unmount the sensor component. The catalytic converter installation starts with disconnecting the components and removing the lower support bracket before lowering the vehicle. Separate the clips retaining the high-pressure line then disconnect the exhaust manifold heat shield. Unplug and detach the electrical connector before taking out the front catalyst monitor sensor. The EGR tube requires removal of its bolt and tube before disconnecting the catalytic converter while getting rid of the nuts. After raising the vehicle support it again ensure that the catalytic converter will stay in position as the support bracket is taken off. Pull out the catalytic converter component along with its front strap while doing away with the gaskets. Begin installation by easing the restraint bolts on the rear support bracket so both faces connect before letting the bracket shift. Insert the new catalytic converter by using new gaskets and nuts and maintaining casual attachment between the converter and flexible pipe using an additional new gasket. Secure the electrical wiring to the rear catalyst monitor sensor before reinstalling it and attaching its connector. Decrease the vehicle height before you firmly tighten all nuts. The EGR tube requires installation of tube and bolt which completes the installation of front catalyst monitor sensor and its electrical connector. The exhaust manifold heat shield requires reinstallation together with tightening the high-pressure line. After lifting and supporting the vehicle again remove the nut to install front bracket while tightening its bolts. Lowly fasten the lower support bracket with new nuts and proceed to tighten all bolts prior to dropping the vehicle to its resting position.
