Need help with diagnosis error msg...

[Quint]

Got that msg when i ran a diagnosis on my car, problem being, i have no idea what a knock sensor is :/

So basically, can anyone give me a heads up on what it is* and/or how to fix it?

Engine is a 1G out of a GA-70 supra.

Cheers

*I'm assumeing it has something to do with fuel detonation

could be because of 3 things:
1) Faulty Sensor (very likely)
2) Broken wire (likely)
3) Faulty ECU (less likely)
Senosor is usually located on the block just under the inlet manifold it looks like big nut (~27mm) with the connector attached to it.
Brand new one is about $120 (give Mr Revhead a email)
Or you could try to get second hand one from wreckers or pickapart (very cheap)... DON'T DROP IT, you will damage it!
