disconnect the battery before you unclip the knock sensor, clean it up with some wd40 then leave the actual battery disconnected for at least half hour, i left mine for 1 hour just in case, that will clear the codes on the ecu, then once reconected turn the engine on and just make sure the engine management light (eml) goes out then give it a try, if the sensor is still faulty it will put the eml light back on and you will again be in limp mode (prob need new sensor) but once the codes are clear and you have left the battery disconnected for an hour give it a go and i reckon it will be fine, knock sensors don't usually go wrong anyway, it is usually just a dirty/bad electrical connection

anyway dc the battery and give it a go an hour later and let us know what happens, i think you will find it will of solved the problem

its the battery rather than the ecu you want to disconnect

thanks for the help m8, ive took knocksensor off the block and cleaned that and cleaned conectors at the top left the batt of and nipped it back up and connected it, ill have ago in about 40mins and see what the score is, it keeps goin in to limp home mode never driven it so dont know what its going to go like in a corsa, it sounded like the back cam was knocking so dont even know if motor is any good. lol

right..... after changing the front knock sensor for a new one, i thought id check the back one as well, where it conects to the red plug at the top there was only one wire the other one had snaped... rejointed the wire but didnt have time to block it to the block. (so only had front knock sensor on) drove it home and ecu light DIDNT come one but still running ruff feels like its missing alot ? any ideas can i run with 1 knock sensor or does it have to be 2 ?

Did you get fault 13 sorted (oxygen sensor / lambda sensor)? That would affect running once the engine has warmed up.

As far as i know the V6 needs both knock sensors running, 1 per bank.

It will have to be both I think. That has to be the reason they are both there.

The fault on mine which looks to be caused by the knock sensor never once bought the EML light on.

[D_a-RR-e_N]

its running at the moment (not very well like) with on on the front and no ecu light coming on, but like i say its missing and doesnt feel like theres no power, but its not it limp home mode.....

is there any faults known on the v6 as ign leads earthing out ?

Not that I know. check out v6calibra.com
