Which Wire Is This

[SteG40]

I've just finished putting the engine back in but I have this plug spare and I can't work out where it goes and i'm wondering if it has anything to do with it not starting. It goes through the bulkhead with the main loom to the ecu. It has fuel and spark turns over ok but won't fire.




Cheers

Wouldn't be the lambda?

Lambdas got 3 pin and earth point wire?

[lance]

yea lambda is 4 pin that could be co pot?
think isv and knock sensor are on a seperate loom part.

[Jezza-7]

ISV sounds good to me.

[samg40]

My moneys on the knock sensor.

[cheys03]

I would also say definately knock sensor - the cable is the same shielded type as on the sensor itself and it's the only sensor that uses shielded cable.
