In today's video tutorial, you will find instructions on how to remove and replace the lambda sensor on a Ford Fiesta ST. First, open the bonnet of your car and remove the plastic engine cover; then disconnect the two battery terminals (positive and negative) by unscrewing the nuts with a spanner. Next, unscrew the screws of the intake hose clamp and disconnect the electrical connector of the mass/air sensor; remove the entire intake duct that extends to the rear of the engine.
