Dumb question !
Can a LT4 knock sensor be used in an OBD1 1993 LT1 ?

 

Yes

 

No, the LT4 (OBDII) knock sensors can only be used in the OBDII cars. You also can't use the LT4 knock module in your 93.

 

If there were such a thing as an LT4 knock sensor, the answer would still be absolutely not.

 

and ditto on post #3.

 

What part of the #3 post is incorrect? The LT4 used OBDII knock sensors.

 

Ditto: repeat an action or statement; "The next speaker dittoed her argument"

 

Oops sorry, it's been a long day.

 

Do you mean knock MODULE? I think the sensors are all the same...

 

There are two different knock sensors.... low impedance for OBD-I and high impedance for OBD-II. But to be technically correct, there is no "unique" knock sensor used in the LT4.... its just an OBD-II sensor, used on all other OBD-II LTx's.

Pretty sure he meant knock module, and not the knock sensor.

 

I'd also like to add that the LT4 knock module doesn't only work on OBDII cars. They also work on 94/95 OBDI cars as well. The module is not able to be replaced in 93 cars.
