o2 sensors vs v8 knock sensor

[SEXPAC]

hi there just wondering how many o2 sensors my vs v8 has

it has pacemakers on it

ive replaced one but cant find another 1

and where does the wire to your knock sensor come from

[grnvs]

They only have one o2 sensor on the passenger side exhaust. (VS series III might be different but, i'm not sure).

Your car will only have a knock sensor if it a hsv or has the 185kw hsv enhanced engine. If it is the ordinary 165 or 168kw version it will not have one. The knock sensor is screwed into the engine block tucked up inbetween the sump and exhuast manifold just near the engine mount. They have only one wire attached to them and it should just feed straight back into the engine loom then on to the ecu.
