Citroen, lambda probe replacement in Israel.
You need to replace the lambda probe (oxygen sensor) in the presence of such signs: car acceleration problems, increased fuel consumption, and the control unit memory failure messages coming from the Check Engine indicator. To replace the device, with the battery off, disconnect the probe from the wiring, remove the sensor wire from the retainers and remove the sensor. After that, install a new probe.
