A while back I swear I read somewhere on the second gen forum that said the first gen's didn't have a knock sensor, but then how can the ecu throw "cylynder x misfire" codes? How does it know if there is a misfire or not if there is no knock sencor?

thanks guys. this is just a random question I have.

The ecu somehow has a way of knowing but i am not sure how its done. I know its not through the KS. The knock sensor is like a microphone and if it detects a change in the frequency it normally gets from the engine it will trigger a light and retard the timing to compensate.

so does that mean there is one?

i think all cars with fuel injection have to have it.

It may be called something else, but it serves the same purpose.

ok, so if I were to get some sort of piggyback ecu adn it had a hookup for aknock sensor then it would still work?

Depends on the ecu controller

aiit mofo's i found out the definate answer... no we do not have a knock sensor.. its all here.. its basically the same info for a multiple misfire..
