Smart Fortwo 451 lambda probe disassembly instructions

Model: Smart Smart 451 - Years 2007-2015
Part: Oxygen sensor

In this tutorial we will see the instructions that will allow us to remove the lambda probe, or the oxygen sensor, on a Smart Fortwo 451. Our sensor is placed on the catalyst of our muffler, which we find on the back; to access it comfortably it will be necessary to remove the rear bumper. Once disassembled we go to identify our lambda probe and with a wrench we go to unscrew it; after having removed it, disconnect the electrical connector of the sensor and replace it with the new one. We just have to screw first by hand and then tighten with the key and reconnect the electrical connector!

How to replace the gear knob on an Opel Astra? Follow these steps: use a plastic lever to disconnect the leather gaiter frame (if you need to replace it). Grip the knob with both hands and pull it upwards (with a strong and decisive motion) until it comes off the gear stick. For installation: fit the new gaiter and position it on the centre tunnel, take the new knob and push it onto the stick, tightening it until fully threaded. Test the movement of the stick on the centre tunnel to ensure the knob is correctly fitted.
