Name that sensor?

Don't know what the sensor is in the picture, but the O2 sensor is attached to the catalytic convertor, if a cat is fitted :)

Hi Justin, Think what you have there is a 'knock sensor'. If you find the lead that should connect to it fair enough but if the cars running ok then forget about it.

I found the plug thats supposed to go into it. I haven't had any difficulty starting it and it looks as though it has been broken for some time. I will get a new one and pop it in as I guess they included it for a purpose :cyclops: thanks again, Justin
