    Lambda Sensor

    Since reading various threads on Lambda Sensors (mine is still the original with 98k miles on the car) I think it's time to change it judging by opinion. So I've ordered a new one, but can anyone tell me where it is on the car and if I need any special knowledge to change it?

    Thanks in advance.

    Removal

    It´s on the downpipe. You will need at wrench or 22 mm "open socket" (hmfmfm whatever that could be called ). Maybe need to disconnect the wires so that they wont get tangled up.

    If it does´nt come off try to drive the car so that it is heated up (use gloves) and try then. Perhaps some WD-40 could help to, but that is better used on a cold downpipe

      There are special sockets available for lambda sensors. They can be very tight. And they may ruin the dp threads also
      Probably there is no space to work with wrenches unless you take the air filter housing out first.
